Dlsmith609 that’s cause a road draft tube on a semi is being vented at the crank case although I will admit Internationals desighn puts a whole in my argument. But there’s reason why Ford went away from that international’s original desighn. It wasn’t emmisons there weren’t any back then

Instead of venting direct to atmosphere, you could put an inline oil catch before putting it into the turbo if you still need to pass emissions standards. You could have that drain to the oil pan
I don't know that you'd want that stuff going into the pan. I have a catch can on my 94 Jeep Cherokee and it's picked up some REALLY nasty crap out of the vapor, almost looks like coffee with creamer and stings your nose like acetone 🤢
I personally prefer the catch can idea, and routing it to the grill to be cooled and condense the vapor, but after seeing what my can has picked up, I'd rather dump that crap in the trash
Just rebuilt my 7.3 and after having to degrease the intercooler 10 times to get all the oil out never again! CCV will forever VTA just like HD engines. I drive a semi and all of em VTA on the years before the greenie wackos were able to cause the current issues. Hats off to your sir for not letting life hold ya down. Keep up the good work!
The channel Gillians Garage put a video up 2 months ago, International made a filter assembly to replace the ccv cover, with a replaceable filter. Only $90 on eBay. It’s a good option for people that don’t like the smell or need to keep it emissions compliant!
One thing I'd like to add; use a metal pipe when the road draft pipe reaches the underside of the truck so that wind doesn't bend those hose and close off the tube.
Good for you sharing the truth and nothing more on this subject. Lots of wrong information out there about it. I have done it on 4 trucks, and not one problem with any of the trucks. Nice truck btw.
I did the cover mod 6 or 8 years ago. The only down side I saw was the smell and oil vapor at idle. 6 months ago I go a single fitting like comes with the Moroso pan evac for race cars. It has a 45° cut and a booster bleed hole for inside the exhaust. Picked up a anti blow back valve from NAPA that's for the old exhaust air injection systems. Welded it in just behind the muffler. Works great. No more smell or vapor and the Wife is much happier!
Seen Bill's video and he has to follow EPA laws when he works on Power Strokes... But he's wrong, I grew up in the Trucking business and all 44 of my Dad's tractors, International Tran Stars, Peterbilt 359, 379 all of these diesel engines had vent tubes hanging strait down the side of the motor!
One of the earliest kind of emission devices for road vehicles was to vent cc gasses back to intake. Think PCV valve on gassers. My 64' 289 gasser vented to atmosphere on valve cover where you fill oil with no issues before pcv's where even thought of, other than a big gimmey oily mess in that area lol. Industrial diesels don't have emissions and why they don't have to vent back to intake. That's all that ccv is on our diesels, a PCV in a sense. You're spot on with correct ccv by-pass hose run. If you have a dip, it WILL eventually fill up that dip and cause a blockage (think p-trap under your sink) or partial block from reduced inner hose diameter= back pressure in crankcase = seals/gaskets will start to leak. 7.3L Navistar International owner here. Well done video Sir.
I love what you say. I always thought Bill was not firing on all cylinders when he brought up that topic. One I will do what I have to to get that engine sewage out and away from ever reaching my combustion chamber or going back into my crankcase. Engineers smarter than most of us went through great pain to come up with an air-fuel ratio that will be the cleanest burning and get the most HP out of the least amount of fuel. Then some i----t puts a bunch of sewage in it. Sorry, this does not compute.
PS I run a 1" line to the inlet and exit of my rather large and well-baffled catch can. A DIY Can that is impressive the amount of engine sewage it will capture in a 5k service.
He’s right about the T444e ccv. As soon as I watched this video I researched the T444e engine and you see clear as day how the tube is routed **with Turbo.** Very well done!
Hey man! Thanks for the knowledge sharing and thank you for the video. Also thank you for staying neutral. Some people come aggressive with all kinds of profanity and even a bit radical. You stayed neutral and straight to the point. Cheers
I've got a 6.0 Powerstroke. It's been Atmosphere vented for over 100 thousand miles now. Zero problems with seals leaking etc. I did it because I started noticing my boots getting dirty and soaked. One day a boot blew off. that was in the year 2012. After delete it has never been a problem since. Still have the truck and have only been using it for heavy hauling. I put a 1" diameter wash machine drain hose on it for the vent tube. I ran it past the cab and dump the gases at the rear wheels. I do notice a tiny bit of mist every once in a while. But hardly any oil mess from it. I never heard of it being demonized out of some theory that it was bad. I assumed everyone knew it was just EPA smog stuff forced on the manufacturers. The only way a straight dump tube would cause a problem would be restriction of it or by it. That would just be a stupid person doing a simple mod wrong. But it would be even more idiotic that a mechanic wouldn't see that the dump was done wrong. Unless they had limited exposure to diesel engines in general. They would probably have been limited to just small trucks with diesel engines being forced to have EPA smog systems. Not familiar with all truck diesel engines. I put over 3 million miles on heavy trucks during my driving career. None of the trucks had CCV systems. Up to 2015 when I retired the last truck I drove, was a direct to atmosphere dumped system. What the hell has happened to people being able to do a little looking into things before following one persons theory. Easy pickings
Anyone considering this mod due to oily and messy CAC boots. This mod is really not necessary for this reason. Buy a good quality set of silicone CAC boots, clean all the fittings really well before installing the boots, tighten clamps nice and tight and you will have NO MORE oil residue on your intercooler pipes/ CAC boots. It’s all in buying high quality boots to solve this issue
People really don't understand Boyle's gas law. If the container is no longer sealed then pressure will equal atmospheric pressure (14.5 PSI). So crank case pressure will equal ambient PSI. I mean I did a CCV catch can on my LS3 and its been running great for 7 years and Its full bolt ons with a vortec.
I have had the ccv on mine for a while, but instead of it venting to the atmosphere I ran it through a catch can filter then back into the turbo, kills 2 birds with one stone, gets rid of the oil from goin into the turbo and intercooler but also keeps that vacuum in the system like the facory.
The only time I see people running crankcase VTA are because they have crankcase pressure problems. I see zero benefit of doing this mod so I’m leaving it as is.
the argument about not running the CCV line to the turbo causing excessive crank pressures makes no sense. That would hold up if there was no vent at all, but rather you are preventing the turbo from causing a vaccuum in the crank case. if anything that's worse because when oil is at lower than atmospheric pressure, it lowers the boiling point and evaporation points.
You guys sound like a bunch of high school auto-shop students. Oh wait.... schoold don't do that anymore. That must be the problem. CCV systems (in most cars called PCV, Posistive crankcase ventilation) have been around snince the 70's and were origionally put in place as emissions devices. Prior to that, all engines were vented into the atmosphere right there at the valve cover. For years, you could even buy these cute little filters people would put in that spot to keep what little oil vapor there was from getting on the engine. Most cars now just rout the CCV/PCV into a vacume line that sucks it straight into the intake. Vent the damn thing wherever you want. It won't really make a difference. Stupid thing to even argue about.
I brought my truck to a shop to get the ccv mod done . The dummies didn’t flip it around and it was kinked . About half way home I noticed my truck smoking . When I got home I saw raw oil in the exhaust and oil coming out of my bell housing . It pressured up and blew oil through the seals . I routed it properly and not an issue since . The shop that did it will be replacing all seals if they start leaking within 50 thousand k . definitely a good mod but like you say …do it correctly and there is no issue
The idea that the overpressure needs to be SUCKED out is absurd. When vented, overpressure relieves itSELF. Sorry but, Bill can be such a moron sometimes. But hey, he's confident. ;-)
I’ve done this for years , first time I did it in (2015) I had a small kink in the hose , didn’t care that much but yes leaks start to happen whatever fixed it not freaked out about it , then put a 3/4” tube properly routed it and no kinks , no leaks no issues no problems 1997 7.3 powerstroke 632,343km on it. 2021 daily driven , do the mod
Nobody is talking about the fact that the crankcase gases are already spent. Meaning the oxygen has already been burned in the combustion process. The more oxygen you can get in the engine the more power you can make so why would you want oxygen depleted air going back into your intake?
Great video. I agree with everything except allowing your condensation oil to run back into the engine. This is sticky soot-filled and fuel-diluted oil which is absolutely bad for your engine.
Thanks for the logical explanation!! Everyone in this community seems to be stuck arguing on the grounds of "what worked for me is best". Can't wait to see how well the millermatic works because I've been looking into buying one for my metal projects.
Can you drill and tap a hole in the exhaust somewhere… nvm instantly answered. Thanks for listening lol. Venturi effect what if it is closer to the end of the exhaust setup like a carb jet. Would there be an issue with running such a long hose? It might be able to actually produce a slight vacuum on the crank case which would be good right.
No reason to do this on an OBS with no intercooler, people should really differentiate between OBS 7.3 and newer 7.3 when discussing mods for this engine.
I'm curious as to why there hasn't yet been the argument of routing the ccv to the spider bypassing the turbo and intercooler pipes, any scientific explanations?
thank you for putting into video form all i have been preaching for years. . oil on a turbine asks particulate to cling causing slight imbalance and buildup leading to junk in the housing bouncing around and eating the turbine. not to mention the boots and intercooler as stated. i have seen several of your videos now and can direct people to your instruction visually rather than try to explain thank you.
I would like to just state the fact it is better to have negative Crank case pressure (CCP) which frees up horsepower. Boosted engines have higher CCP which then puts pressure on the wrong side of piston rings hence robbing horsepower and run the chance of blowing out oil seals. As said earlier by ssomeone else hi rev or boosted racing engines use vacuum pumps to solve this problem which is the best solution for this problem but COSTLY. I tried on my 7.3 the CCV from doghouse to under truck and at 28 to 30 psi of boost I blow out the o ring on my dipstick tube. Mind you NO leak before mod and I had already replaced the dipstick tube o rings. Pain in my butt but I replace o rings AGAIN and I went with a catch can in my CCV and routed it back to intake tube and the same tune. Problem solved for about 50k miles and my truck has 250k on it. I am not saying venting CCV under truck is bad but it isn't the best solution. Mind you the old 7.3's in big trucks or school busses didn't run the boost levels that these hot rod 7.3's with tunes, injectors, HPOPs.
@@miker0257 I made my own catch can1.5" pvc, drain & copper drain line on bottom of can, mounted on the firewall. Turned CCV doghouse around plumbed it between that and intake.
it dosent matter to much on these engines do what you want .the reason why high hp engines have thie routed into the intake is because of crank case pressure if your turning 9000 rpm you want a vaccume to pull gasses out. but the 7.3 only 3500 or so the gases that pass by the rings are enough to push the vapors out you dont need a vaccume if you want to re burn the gas and oil vapors run a hose up to your air cleaner box befor the air filter then the fiklter will catch most of the oil vapor and the rest will be sucked up in your intake
If you care about the enviroment, and your engine, put a system that uses the seperator for the oil to crankcase, like FleetGaurd and others use on industrial engines.
Also I've seen, Bless their Heart, disconnect the CCV and put a plug in it! Total dumb arses :) But I'm going to do want you said, to run the tube up over the brake master then strait down! Cool info for Power Stroke owners to know! Thanks!
I'm amazed why people do these foolish mod,s the reason you have oil going into your turbo is because you have a dirty air filter. Look at how the CCV port is pointing in the intake tube !!!!! it's pointing towards the air filter pushing air the other way, if it was pointing towards the turbo yes it would suck the oil vapors into the motor. I have been working on motors over 50 years DON'T WRECK YOUR MOTOR DOING THIS FOOLISH MOD!!!
I own both 12 valve Cummins and an OBS 7.3 Powerstroke. I was very surprised to see the CCV on a 6.7 Cummins in a 2019 medium duty KW venting to the atmosphere unlike the same engine used in an Automotive application like the Ram pickup.
Thank you so much, I’ve been driving around mosquito fogging oil smoke at every stop, it was really bad. I went ahead and did what you did this morning after watching your video. I also cleaned my air filter while I was there and I think that was my problem.
Oil catch can Do the ccv mod like so Buy a cylinder catch can You can run a line from the crank case To the catch can. Then run another line to the intake to pull the vapor. The oil catches in the can and falls to the bottom. The catch can itself is vented to the atmosphere and had a little filter on the top to keep the dust out.
I would trust what Bill says being he's work on literally THOUSANDS of these engines. He's the man when it comes to powerstrokes. Why even question what he said is a mystery to me. Tractors and all those other machines your talking about run totally different than these motors. To each their own though.
I question him because it’s one mechanic vs an entire company of engineers that designed an engine a specific way. As well as a very long track record of reliable t444e engines in international trucks. Like we both said, to each their own. I have nothing against someone keeping their ccv stock.
I just dont get why people like to say they did this mod if it does nothing for the vehicle. The pros of doing it are all hypothetical. People just don't want to admit that the only reason is because old medium duty trucks vented to air and its cool to be like them for some reason.
Alright chief if your in ca. these motors are still required to go thru smog even tho they have no production smog equipment. Visual check is a fail if you are routed to atmosphere. That’s why you go to a catch can and back to the intake
One way if someone is no ok with it venting outside. A catch can will help catch the oil in vapor. But I agree with you on just venting it under the truck.
So when the piston is on its down stroke it is fighting that crankcase pressure as it is trying to go down! You have a very good idea with the vent. Do you add any kind of PCV valve on the hose to prevent it from sucking air back into the valve cover?
I don’t know exactly how these engines are valences but I’d imagine that as one piston is on its down stroke another is on it’s up stroke. Balancing that effect out. Also, in general diesels will have enough gas going past the rings that there will always be positive crank case pressure.
I'd run a catch can then back into the intake, I did see someone of facebook bought a kit from International that is a CCV mod. You replaced the doghouse with this funny looking thing that has a filter in it for catching the oil. I would actually get that kit if I really thought it might save my engine. My 01 7.3L has over 313,000 miles and runs fine and my 03 7.3L has 151,000 miles and is darn near brand new still when it comes to the engine.

I'll leave my 99 CC vent the way it came from ford. A little oil don't bother me. Good video very informative point of view........The guy in the comment that called Bill a fool; Bill has helped me and millions of other's in so many different ways how take care and fix our trucks and save boatloads of money in the process. Also to be honest the negative remarks were very uncalled for.
Very compelling case. Previous owner of my excursion did the ccv mod to vent to atmosphere. I switched back to vent into turbo. Now I’m second guessing myself.
So, I went the route of using the commercial International CCV Pre filter so it acts as a catch can prior to venting to the atmosphere. I did this after having issues with just venting to the atmosphere. I actually overengineered this simple mod and did it the way it was from the factory on the commercial trucks. I used line diameter, length, general placement, etc. Unfortunately, I fought oil leaks like crazy. I had to do my oil pan gasket three times due to crankcase pressure before finally going back to stock. I have not had a problem since. I wish it worked for me. I now deal with the oil in my intake piping but it was not worth it for me. I am very mechanically capable and have built many cars and motorcycles over the years. It is certainly NOT an installation issue. My guess is that there is enough variation in the 7.3 build specs that some trucks are not able to utilize this modification. I have a 2000, F350. Possibly the year matters as internals are different in the early model trucks. I dunno...
Haha bill has a lot of really good information out there. I have watched a tone of his videos but a lot of people agree that there’s a few things that are just a little ehh.
@@klikliks_service Bill says a lot of stupid shit, with as many videos as he has out there he is bound to have a few bonehead ones. the one where he said they had a 'wiring harness issue' that made the truck unfixable??? its a couple of wires man anyone can fix a harness.
@@xxxmikeyjock Bill is very unprofessional. I don't care how bad a customer makes you mad you don't make a video picking the truck apart and trashing the customer. That's grade school crap.
It is just a mod like all the others you can choose to do or not to do. I like hearing all the sides b4 i do anything to my truck. I personally have not done this mod because of the off chance of messing something up. For now my turbo is fairly clean. Great Vid, keep up the good work. Now, do one on the 10k mod, that will get people chatting away :)
Been a Porsche and diesel mechanic for decades. Draft tubes don’t help your engine, are horrible for the environment, and everybody’s health. You sir, should do some more research. There’s absolutely no benefit to a CCV delete, because the oil isn’t damaging your turbo or piping. It’s actually fuel for a diesel! The only reason International doesn’t install them is simple, it’s cheaper for them not to. The downside is your crankcase is now open to the atmosphere and will allow moisture to get in. International doesn’t care about that either because it won’t matter until most people (not me) are ready for a new truck anyways. Have you looked into why the PCV system was invented? Not emissions, the US Army needed diesel tank engines that didn’t flood the crankcase during deep fording operations in WWII. Figure it out.
Best thing to do with these trucks is put a double locking turqe converter in it no problem after that have deep pockets when you have it done I've done everything to mine next step is a turner or a chip but ill bet it'll smoke most of these trucks let's just say I have 8 grand in mine 01 4x4 off road powerstroke diesel quad cab an it has 89500 miles on it an at 86500 when I bought it the thing had a broke piston in the 8th cyclender my buddies 95 broke the 8th piston too so you've really got to watch out for that one sign is it will smoke like hell the whole time it runs an you'll hear it too so beware buyers .................
Good veedio, I’v ben running my vent tuub to the interior cab of me truk fore the past 4 yeers and haven’t nowticed as any prawblems. In fact I thienk the fumes are even making me more smarter !!!!
Just asking , to stop the issue with vent to the ground, with the breather venting to the back , how about running the hose up and looping it over the top of the master cyl.and around and hook the hose back to the intake fitting. Would that distance in the hose going up hill be enough for the oil to run back in the breather ? My 01 7.3 with 186k doesn't seem to have that much oil in the intake . I have tried the 6637 , but since it came with a AIS filter that is much quiter ,I like it . Thanks for all your advise on the old 7.3s .
Ok. You didn’t exactly state your position..... are you for or against the mod? I’m sure most got what you meant but some of us may not. Are you saying IH knew what they were doing so don’t mess with it ? Or do you mean that the original design was changed by Ford so it’s a good idea to do the mod?
I used high temp silicone hose I've got it aimed at the rear drive shaft front universals keeps done nice and lubed. I was going to put a catch can. But I did not. What are your thoughts on a catch can?
You could also use a sediment bowl in the suction line to capture the oil in the line. Better yet install a vacuum pump to the crankcase vent line with a sediment bowl. The vacuum in your crankcase should give you a bit more power. The only maintenance is draining the sediment bowl or filter trap assembly.
My international is vintage back into the turbo just like the Ford with the t444e and I have a medium duty international and everything on the engine is set up just like it is on my Ford
Well I know on big diesel engines(at least the older cats and 60 series Detroit's are vented to the atmosphere)so I nothing wrong with doing it with a little ole 7.3
I have a 96 with a intercooler kit and I put a oil catch can on my ccv, should I take the oil catch can off and run it to atmosphere or just keep my catch can on and run it out under my truck?
I think the catch can is a nice idea. I thought about doing a catch can on mine running back to the intake. That would keep the suction on the system but solve the oil mess. Since you already have it install I wouldn’t remove it unless it was undersized.
Young man I really like the fact that your still working on trucks and hitting the woods not letting that chair get in your way. Hope you stick a nice one bud!

Having oil mist going underneath your truck will prevent rust for those people like me that live were snow falls and they use salt on the roads.

One I will do what I have to to get that engine sewage out and away from ever reaching my combustion chamber or going back into my crankcase. Engineers smarter than most of us went through great pain to come up with an air-fuel ratio that will be the cleanest burning and get the most HP out of the least amount of fuel. Then some i----t puts a bunch of sewage in it. Sorry, this does not compute.
PS I run a 1" line to the inlet and exit of my rather large and well-baffled catch can. A DIY Can that is impressive the amount of engine sewage it will capture in a 5k service.
Just run a sealed catch can I really don’t understand why people don’t understand
He’s right about the T444e ccv. As soon as I watched this video I researched the T444e engine and you see clear as day how the tube is routed **with Turbo.** Very well done!
I have triple 4 in school buses and they are not vented.
Hey man! Thanks for the knowledge sharing and thank you for the video. Also thank you for staying neutral. Some people come aggressive with all kinds of profanity and even a bit radical. You stayed neutral and straight to the point. Cheers
My buddy runs a 1-in inlet 1-in outlet catch can on his vent. To prevent any messes. Mine is still factory setting so I can't give no advice
I've got a 6.0 Powerstroke. It's been Atmosphere vented for over 100 thousand miles now. Zero problems with seals leaking etc. I did it because I started noticing my boots getting dirty and soaked. One day a boot blew off. that was in the year 2012. After delete it has never been a problem since. Still have the truck and have only been using it for heavy hauling.
I put a 1" diameter wash machine drain hose on it for the vent tube. I ran it past the cab and dump the gases at the rear wheels. I do notice a tiny bit of mist every once in a while. But hardly any oil mess from it.
I never heard of it being demonized out of some theory that it was bad. I assumed everyone knew it was just EPA smog stuff forced on the manufacturers.
The only way a straight dump tube would cause a problem would be restriction of it or by it. That would just be a stupid person doing a simple mod wrong. But it would be even more idiotic that a mechanic wouldn't see that the dump was done wrong. Unless they had limited exposure to diesel engines in general. They would probably have been limited to just small trucks with diesel engines being forced to have EPA smog systems. Not familiar with all truck diesel engines.
I put over 3 million miles on heavy trucks during my driving career. None of the trucks had CCV systems. Up to 2015 when I retired the last truck I drove, was a direct to atmosphere dumped system. What the hell has happened to people being able to do a little looking into things before following one persons theory. Easy pickings
You’re amazing bro. Love all your videos
I appreciate that!
Anyone considering this mod due to oily and messy CAC boots. This mod is really not necessary for this reason. Buy a good quality set of silicone CAC boots, clean all the fittings really well before installing the boots, tighten clamps nice and tight and you will have NO MORE oil residue on your intercooler pipes/ CAC boots. It’s all in buying high quality boots to solve this issue
High quality boots definitely make a big difference
@@LivingOnWheels excellent videos!! I have learned so much about my 99 7.3 thanks to your extensive knowledge and precise explanations!!
People really don't understand Boyle's gas law. If the container is no longer sealed then pressure will equal atmospheric pressure (14.5 PSI). So crank case pressure will equal ambient PSI. I mean I did a CCV catch can on my LS3 and its been running great for 7 years and Its full bolt ons with a vortec.
I have had the ccv on mine for a while, but instead of it venting to the atmosphere I ran it through a catch can filter then back into the turbo, kills 2 birds with one stone, gets rid of the oil from goin into the turbo and intercooler but also keeps that vacuum in the system like the facory.
Ive thought about doing the same. Just haven’t gotten around to routing it up.
@@therealaustinbrown2712 At some point I will probably be adding a catch can to my rig.
@@LivingOnWheels yeah its not a bad idea, but atleast yours doesn't leak oil so not i big deal for now.
@@therealaustinbrown2712 That's my mindset as well.
Im in the process of doing this too. Which catch can did you go with and where exactly did you mount yours?
The only time I see people running crankcase VTA are because they have crankcase pressure problems. I see zero benefit of doing this mod so I’m leaving it as is.
the argument about not running the CCV line to the turbo causing excessive crank pressures makes no sense. That would hold up if there was no vent at all, but rather you are preventing the turbo from causing a vaccuum in the crank case. if anything that's worse because when oil is at lower than atmospheric pressure, it lowers the boiling point and evaporation points.
You guys sound like a bunch of high school auto-shop students. Oh wait.... schoold don't do that anymore. That must be the problem. CCV systems (in most cars called PCV, Posistive crankcase ventilation) have been around snince the 70's and were origionally put in place as emissions devices. Prior to that, all engines were vented into the atmosphere right there at the valve cover. For years, you could even buy these cute little filters people would put in that spot to keep what little oil vapor there was from getting on the engine. Most cars now just rout the CCV/PCV into a vacume line that sucks it straight into the intake. Vent the damn thing wherever you want. It won't really make a difference. Stupid thing to even argue about.
I brought my truck to a shop to get the ccv mod done . The dummies didn’t flip it around and it was kinked . About half way home I noticed my truck smoking . When I got home I saw raw oil in the exhaust and oil coming out of my bell housing . It pressured up and blew oil through the seals . I routed it properly and not an issue since . The shop that did it will be replacing all seals if they start leaking within 50 thousand k . definitely a good mod but like you say …do it correctly and there is no issue
The idea that the overpressure needs to be SUCKED out is absurd. When vented, overpressure relieves itSELF. Sorry but, Bill can be such a moron sometimes. But hey, he's confident. ;-)
Old hotrodders have been venting crankcase vents to the outside world for DECADES!
I’ve done this for years , first time I did it in (2015) I had a small kink in the hose , didn’t care that much but yes leaks start to happen whatever fixed it not freaked out about it , then put a 3/4” tube properly routed it and no kinks , no leaks no issues no problems 1997 7.3 powerstroke 632,343km on it. 2021 daily driven , do the mod
Semis have the same thing. We call it a blow by. Now i gotta go check where mine is lol. Thanks for the info
Sold! Solid Argument and I double checked what you said also the 90 is the weak link! Appreciate your videos!
Nobody is talking about the fact that the crankcase gases are already spent. Meaning the oxygen has already been burned in the combustion process. The more oxygen you can get in the engine the more power you can make so why would you want oxygen depleted air going back into your intake?
Great video. I agree with everything except allowing your condensation oil to run back into the engine. This is sticky soot-filled and fuel-diluted oil which is absolutely bad for your engine.
Thanks for the logical explanation!! Everyone in this community seems to be stuck arguing on the grounds of "what worked for me is best". Can't wait to see how well the millermatic works because I've been looking into buying one for my metal projects.
I try to be logical. As for the welder, I love it so far
Can you drill and tap a hole in the exhaust somewhere… nvm instantly answered. Thanks for listening lol.
Venturi effect what if it is closer to the end of the exhaust setup like a carb jet. Would there be an issue with running such a long hose? It might be able to actually produce a slight vacuum on the crank case which would be good right.
On a international 4700 with the dt444 it is vented to side of the block, my dt466 is the same way no problems. It doesn't leak oil out the pipe.
I wish diesel tech Ron could comment on this...
Me too. 🙏
No reason to do this on an OBS with no intercooler, people should really differentiate between OBS 7.3 and newer 7.3 when discussing mods for this engine.
Stupid question,can u do a pressure test of some sorts before and after mid? That would give all proof u need?
Thumbs up on this one LOW. Best Wishes & Blessings Keith Noneya
Thankyou
I'm curious as to why there hasn't yet been the argument of routing the ccv to the spider bypassing the turbo and intercooler pipes, any scientific explanations?
I’d would say because that is the pressure side of the system which would mean you’d actually be pressurizing your crank case from the turbo boost.
@@LivingOnWheels thought it'd be that way just couldn't assume, just a late night thought while driving listening to my ccv mod 7.3 lol
thank you for putting into video form all i have been preaching for years. . oil on a turbine asks particulate to cling causing slight imbalance and buildup leading to junk in the housing bouncing around and eating the turbine. not to mention the boots and intercooler as stated. i have seen several of your videos now and can direct people to your instruction visually rather than try to explain thank you.
I would like to just state the fact it is better to have negative Crank case pressure (CCP) which frees up horsepower. Boosted engines have higher CCP which then puts pressure on the wrong side of piston rings hence robbing horsepower and run the chance of blowing out oil seals. As said earlier by ssomeone else hi rev or boosted racing engines use vacuum pumps to solve this problem which is the best solution for this problem but COSTLY.
I tried on my 7.3 the CCV from doghouse to under truck and at 28 to 30 psi of boost I blow out the o ring on my dipstick tube. Mind you NO leak before mod and I had already replaced the dipstick tube o rings. Pain in my butt but I replace o rings AGAIN and I went with a catch can in my CCV and routed it back to intake tube and the same tune. Problem solved for about 50k miles and my truck has 250k on it.
I am not saying venting CCV under truck is bad but it isn't the best solution. Mind you the old 7.3's in big trucks or school busses didn't run the boost levels that these hot rod 7.3's with tunes, injectors, HPOPs.
Which catch can did you go with and what location did you install it in?
@@miker0257 I made my own catch can1.5" pvc, drain & copper drain line on bottom of can, mounted on the firewall. Turned CCV doghouse around plumbed it between that and intake.
@@kuzz7919 do you happen to have any videos of it installed on yours?
@@miker0257 I might have posted photos on FTE forum. It has been 8 or 10 yrs ago I am not sure
@@kuzz7919 no worries, I'll see if I could locate some
Thanks man. Good Info
it dosent matter to much on these engines do what you want .the reason why high hp engines have thie routed into the intake is because of crank case pressure if your turning 9000 rpm you want a vaccume to pull gasses out. but the 7.3 only 3500 or so the gases that pass by the rings are enough to push the vapors out you dont need a vaccume if you want to re burn the gas and oil vapors run a hose up to your air cleaner box befor the air filter then the fiklter will catch most of the oil vapor and the rest will be sucked up in your intake
If you care about the enviroment, and your engine, put a system that uses the seperator for the oil to crankcase, like FleetGaurd and others use on industrial engines.
I feel bad for people at drive through windows because the haze goes right up into their window 🤣
Have you put a catch can on it yet
I wonder why nobody has just ran it to connect with there exhaust pipe, yea it more work, but atleast it will mix with the exhaust
Also I've seen, Bless their Heart, disconnect the CCV and put a plug in it! Total dumb arses :) But I'm going to do want you said, to run the tube up over the brake master then strait down! Cool info for Power Stroke owners to know! Thanks!
I'm amazed why people do these foolish mod,s the reason you have oil going into your turbo is because you have a dirty air filter. Look at how the CCV port is pointing in the intake tube !!!!! it's pointing towards the air filter pushing air the other way, if it was pointing towards the turbo yes it would suck the oil vapors into the motor. I have been working on motors over 50 years DON'T WRECK YOUR MOTOR DOING THIS FOOLISH MOD!!!
You obviously have a lot of experience. Care to explain how this mod will wreck your motor?
Does anyone install oil catch cans on 2000 7.3’s
There definitely been plenty of people that have done it
@@LivingOnWheels would you recommend the catch can for the 7.3?
Messing with the ccv is just unnecessary tinkering. The oil vapors going into the turbo reduces heat so I'll keep mine stock.
That’s a theory I’ve never heard before. Like I said though. To each their own.
how does hot oil soaked vapor cool the incoming air? lol I mean seriously logical thinking should come natural.
@@LivingOnWheels his comment is theory for sure, his own.
Oil coats the turbo internals, burns off, and the cycle continues. Lubes it and cools turbo temps. Did I break it down for you enough, genius?
awe schucks, so ya might hurt some feelings. oh well. keep doing what ya do
I own both 12 valve Cummins and an OBS 7.3 Powerstroke. I was very surprised to see the CCV on a 6.7 Cummins in a 2019 medium duty KW venting to the atmosphere unlike the same engine used in an Automotive application like the Ram pickup.
my dad did this to his 7.3 and it meakes it stink twice as much at idle. I kept the ccv system in my 7.3 if it works dont fix it imo.
Thanks for the big brain you have! Great video
Thank you so much, I’ve been driving around mosquito fogging oil smoke at every stop, it was really bad. I went ahead and did what you did this morning after watching your video. I also cleaned my air filter while I was there and I think that was my problem.
Thanks for the vid mine has ccv to atmosphere
Oil catch can
Do the ccv mod like so
Buy a cylinder catch can
You can run a line from the crank case
To the catch can.
Then run another line to the intake to pull the vapor.
The oil catches in the can and falls to the bottom.
The catch can itself is vented to the atmosphere and had a little filter on the top to keep the dust out.
Would definitely be a good setup
I would trust what Bill says being he's work on literally THOUSANDS of these engines. He's the man when it comes to powerstrokes. Why even question what he said is a mystery to me. Tractors and all those other machines your talking about run totally different than these motors. To each their own though.
I question him because it’s one mechanic vs an entire company of engineers that designed an engine a specific way. As well as a very long track record of reliable t444e engines in international trucks. Like we both said, to each their own. I have nothing against someone keeping their ccv stock.
A lot of Race cars vent their crank case into the exhaust.
with a check valve to prevent ex pressure from entering the crank case
I just dont get why people like to say they did this mod if it does nothing for the vehicle. The pros of doing it are all hypothetical. People just don't want to admit that the only reason is because old medium duty trucks vented to air and its cool to be like them for some reason.
International actually makes a filter kit for this. Filters it and sends it back to intake with no oil. Not sure of part #
Yup. Not sure on part number either but I have seen it.
Alright chief if your in ca. these motors are still required to go thru smog even tho they have no production smog equipment. Visual check is a fail if you are routed to atmosphere. That’s why you go to a catch can and back to the intake
Yes, a catch can would be a nice option for the California people.
One way if someone is no ok with it venting outside. A catch can will help catch the oil in vapor. But I agree with you on just venting it under the truck.
So when the piston is on its down stroke it is fighting that crankcase pressure as it is trying to go down! You have a very good idea with the vent. Do you add any kind of PCV valve on the hose to prevent it from sucking air back into the valve cover?
I don’t know exactly how these engines are valences but I’d imagine that as one piston is on its down stroke another is on it’s up stroke. Balancing that effect out. Also, in general diesels will have enough gas going past the rings that there will always be positive crank case pressure.
I'd run a catch can then back into the intake, I did see someone of facebook bought a kit from International that is a CCV mod. You replaced the doghouse with this funny looking thing that has a filter in it for catching the oil. I would actually get that kit if I really thought it might save my engine. My 01 7.3L has over 313,000 miles and runs fine and my 03 7.3L has 151,000 miles and is darn near brand new still when it comes to the engine. Nice looking grill

Great video, appreciate the information! Checking my 7.🌳 in the morning to see where my CCV in point'n! Happy New Year, my friend!
thanks for your video , and honesty
Love the intro nice rig!!!!
Agree with you totally!
I'll leave my 99 CC vent the way it came from ford. A little oil don't bother me. Good video very informative point of view........The guy in the comment that called Bill a fool; Bill has helped me and millions of other's in so many different ways how take care and fix our trucks and save boatloads of money in the process. Also to be honest the negative remarks were very uncalled for.
Good information buddy
Very compelling case. Previous owner of my excursion did the ccv mod to vent to atmosphere. I switched back to vent into turbo. Now I’m second guessing myself.
It’s not really going to harm anything either way. More just personal preference.
So, I went the route of using the commercial International CCV Pre filter so it acts as a catch can prior to venting to the atmosphere. I did this after having issues with just venting to the atmosphere. I actually overengineered this simple mod and did it the way it was from the factory on the commercial trucks. I used line diameter, length, general placement, etc. Unfortunately, I fought oil leaks like crazy. I had to do my oil pan gasket three times due to crankcase pressure before finally going back to stock. I have not had a problem since. I wish it worked for me. I now deal with the oil in my intake piping but it was not worth it for me. I am very mechanically capable and have built many cars and motorcycles over the years. It is certainly NOT an installation issue. My guess is that there is enough variation in the 7.3 build specs that some trucks are not able to utilize this modification. I have a 2000, F350. Possibly the year matters as internals are different in the early model trucks. I dunno...
Wow, taking a stab at Bill huh, I see where your coming from though.
Haha bill has a lot of really good information out there. I have watched a tone of his videos but a lot of people agree that there’s a few things that are just a little ehh.
Bill is a sales man. That's all I take him for.
@@klikliks_service Bill says a lot of stupid shit, with as many videos as he has out there he is bound to have a few bonehead ones. the one where he said they had a 'wiring harness issue' that made the truck unfixable??? its a couple of wires man anyone can fix a harness.
@@xxxmikeyjock Bill is very unprofessional. I don't care how bad a customer makes you mad you don't make a video picking the truck apart and trashing the customer. That's grade school crap.
It is just a mod like all the others you can choose to do or not to do. I like hearing all the sides b4 i do anything to my truck. I personally have not done this mod because of the off chance of messing something up. For now my turbo is fairly clean. Great Vid, keep up the good work. Now, do one on the 10k mod, that will get people chatting away :)
Exactly. Everyone’s gotta decide what they want to do. Maybe I’ll do the 10k mod haha
HOW DARE YOU! 😝
CCV3550-FRD-02 however, if you increase the power some suggest using CCV4500.
Been a Porsche and diesel mechanic for decades. Draft tubes don’t help your engine, are horrible for the environment, and everybody’s health. You sir, should do some more research. There’s absolutely no benefit to a CCV delete, because the oil isn’t damaging your turbo or piping. It’s actually fuel for a diesel! The only reason International doesn’t install them is simple, it’s cheaper for them not to. The downside is your crankcase is now open to the atmosphere and will allow moisture to get in. International doesn’t care about that either because it won’t matter until most people (not me) are ready for a new truck anyways. Have you looked into why the PCV system was invented? Not emissions, the US Army needed diesel tank engines that didn’t flood the crankcase during deep fording operations in WWII. Figure it out.
Best thing to do with these trucks is put a double locking turqe converter in it no problem after that have deep pockets when you have it done I've done everything to mine next step is a turner or a chip but ill bet it'll smoke most of these trucks let's just say I have 8 grand in mine 01 4x4 off road powerstroke diesel quad cab an it has 89500 miles on it an at 86500 when I bought it the thing had a broke piston in the 8th cyclender my buddies 95 broke the 8th piston too so you've really got to watch out for that one sign is it will smoke like hell the whole time it runs an you'll hear it too so beware buyers .................
Good veedio, I’v ben running my vent tuub to the interior cab of me truk fore the past 4 yeers and haven’t nowticed as any prawblems. In fact I thienk the fumes are even making me more smarter !!!!
Just asking , to stop the issue with vent to the ground, with the breather venting to the back , how about running the hose up and looping it over the top of the master cyl.and around and hook the hose back to the intake fitting. Would that distance in the hose going up hill be enough for the oil to run back in the breather ? My 01 7.3 with 186k doesn't seem to have that much oil in the intake .
I have tried the 6637 , but since it came with a AIS filter that is much quiter ,I like it . Thanks for all your advise on the old 7.3s .
Ok. You didn’t exactly state your position..... are you for or against the mod? I’m sure most got what you meant but some of us may not. Are you saying IH knew what they were doing so don’t mess with it ? Or do you mean that the original design was changed by Ford so it’s a good idea to do the mod?
I used high temp silicone hose I've got it aimed at the rear drive shaft front universals keeps done nice and lubed. I was going to put a catch can. But I did not. What are your thoughts on a catch can?
Good luck on the hunt! Love that venison
You could also use a sediment bowl in the suction line to capture the oil in the line. Better yet install a vacuum pump to the crankcase vent line with a sediment bowl. The vacuum in your crankcase should give you a bit more power. The only maintenance is draining the sediment bowl or filter trap assembly.
Uhjh a catch can lol?
My international is vintage back into the turbo just like the Ford with the t444e and I have a medium duty international and everything on the engine is set up just like it is on my Ford
He is correct!! Cummins ISX and Caterpillar and many other engines are vented to the atmosphere! ISX has a new reusable replacement Crank case filter
Well I know on big diesel engines(at least the older cats and 60 series Detroit's are vented to the atmosphere)so I nothing wrong with doing it with a little ole 7.3
I have a 96 with a intercooler kit and I put a oil catch can on my ccv, should I take the oil catch can off and run it to atmosphere or just keep my catch can on and run it out under my truck?
I think the catch can is a nice idea. I thought about doing a catch can on mine running back to the intake. That would keep the suction on the system but solve the oil mess. Since you already have it install I wouldn’t remove it unless it was undersized.
@@LivingOnWheelsthanks man I appreciate it!
I installed mine and took it off because I was having to much what cloudy smoke coming out.
