Do you feel having an oil catch cans off of the PCV valve in conjunction with the CRC cleaner and new PCV valve every 20K would be adequate to keep carbon in check on GDI's? I have a Hyundai with a 2.4L. Thank you.
Too much effort ,, get the big chunks off and then use BG carbon remover or go to a restaurant supply store and get the professional carbon remover for pots/pans (same as BG but a quarter of the price) .. turns that crap to liquid in MINUTES....
i have a 2015 ford expedition 3.5 eco boost and it is having a issue where when you accelerate up to around 2500 to 3500 rpms to pass someone or enter a freeway it starts missing and the check engine light flashes. would you say this is a carbon issue as well...it has happened cold start as well but not until it climbs a hill
Man keep this up. Regardless if I ever do any of these manual repairs myself, just great education for use when talking with mechanics and shops. The more you know!
Did this on my 14 focus st. Before that it had a few misfires and what not. The carbon build up was pretty bad with 82k. I used crc and let it soak for about an hr on each valve while it was fully submerged. Then scrub with a hard thin brush. Then I would use a small vacuum attachment on my shop vac and suck it up. Repeat until it was smooth. Then installed catch cans 😁. She definitely idles better and has less misfires. Worth the troubles. I'd tape off the other valves that are already clean to keep them from getting debris inside from the dirty ones. great vid and info. Wish I found this sooner.
I just did this on my Focus ST! I blasted it with walnuts tho. 180k miles!! The valves were WICKED!! What a brain fart of a design... Car ran so much better afterwards. Totally worth the effort.
Thanks for making this video, I just had the misfire issue for the first time at 107k and I was at a loss on how to clean the valves. The method you showed us worked great.
Have a Mazda CX-5 with GDI. I’ve utilized the BG kit at approximately 80,000 miles. Engine oil is also important for reducing carbon build up. I use Pennzoil Platinum Full synthetic engine oil as well.
Perfect timing for this video. I'm wrapping up the timing chain job on my 3.5 ecoboost today. Your videos are incredible. Thank you Thank you Thank you!
How many miles on your 3.5? I am looking at maybe buying a used Ford Explorer Platinum with twin turbo 3.5L and 50k miles, and I'm a little concerned about durability. Not sure if it's worth buying one of these Ecoboost engines. Thanks
@@ChevySS1968 only 80k miles but that doesn't tell the whole story. I have used this truck a lot for hauling and haven't had a single issue other than this major one. If I can get another 5 or 6 years of use from the truck with no other issues I'll be happy.

@@easton._.141 A Lot of Shops can do that, about an hour or two for the blasting and whatever time it takes for dis and re-assembly. Periodic engine treatment will help keep down on buildup but on the other hand you done reeeeal good on getting that many miles without issue. I do not know if Ford has a top engine cleaner, personally I use GM product and swear by it. Way better than the CRC crap in my opinion.
Nice , appreciate the heck out of you and your videos. I have a 96 4 valve cobra with the same design issue . Different design but same issue . I cleaned mine with 1/2” round wire brush. To get around the valve I bent the end of it around itself , And then a slight 20deg bend. I use carb clean to break it up . Then I use brake clean to sterilize it . Blowing with a air gun covered with a rag so it doesn’t go everywhere.
Thanks for sharing. Just goes to show why GDI coupled with a standard PCV system is a major design flaw in modern engines that are built this way. Any engine that uses GDI should come from the factory with an oil catch can or include redundant port injectors to keep the valves clean.
No strict need for a catch can but you do need a good air/oil separator in the PCV system, to get the oil mist out of the blowby and send it back to the sump. A catch can is just another secondary air/oil separator, retrofitted because the OEM one is inadequate (or absent).

Just called two dealers to see what they would charge to clean my valves. Both want to charge me between $135-$300 for doing the same thing I’ve already been doing with CRC’s GDI cleaner; I asked what the service consisted of… they told me they spray/ fog the intake. That’s what I’ve been doing on a regular basis… so, I’ll be doing this process myself. They’ll probably want $2000 to do it.

Junk engine! Requires major maintenance after only 80K. So glad my 99 Taurus has a 3.0 Vulcan - 22 years old, runs perfectly, never been apart. Thanks for another great vid, always learn something here.
uhhh that's inherent with every GDI engine from every manufacturer, Mazda, VW, Honda, Subaru. Newer engines from Ford and Toyota have both port and direct injection system so this is no longer a problem.
Your 3.0 vulcan also only makes 140hp, and 160ftlbs of torque. One of fords ecoboost engines, the 1.0 3 cylinder engine makes the same power and torque as your 3.0 v6 while getting over 50mpg.
Ford senior master tech her just a tip try using the Motorcraft carb cleaner (PM3) just poor it in the intake port and cover the valve let it sit for 30 mins and blow it out it will look new - great video
Should this be done as a preventative maintenance procedure? I am about to install a catch can on my 70000k mile EcoBoost, so as long as I am pulling the intake manifold off, maybe I should take on a cleaning on as well?
I am using wynn's direct injection valve cleaner as we speak, together with some brushes. I taped off one of the cyllinders cause that one is open i will now let it dwell for the night and see what it does, the ports toward the valve cleaned up very well so i have high hopes.
My catch can on my 2013 F-150 3.5 Ecoboost catches about 1/2 a Dixie-cup of syrupy, coffee consistency fluid between each oil change. Not sure how much build-up that saves on the valves, but at least I can attest to it catching some of the blow-by.
i have a carbon vac machine but with the intake desigs of todays cars the machine is not sufficent in cleaning the carbon off the valves. Renoving the intake on todays down draft intakes is the best way to get a good scrub on the intake valves. Also allows you to clean all the oil buildup from the pcv system in the intake by removal. Sea foam works good for me.
@@andrewrich6198 It can. It is a GDI engine. In 2017+ they switched to use both GDI and port injection, so the fuel should help keep the valves cleaner.
I have a 16 escape 1.6l that I have torn apart right now because it has all the symptoms of a bad pcv valve, to find out it doesn't have a pcv valve. It instead has an air oil separator. Have you ever had to replace one? And I figured while I had the intake off I would clean the valves because they were worse than the ones in video
I’ve got a Chevy v8 in my g8, I’m here just to see how your carbon cleaning goes lol I got injured, went a bit too long on an oil change and my pcv sucked in and coated up my intake lol baked on crap. It’s incredible since it’s not a direct injected engine.
If I were doing all this work to clean the intake valves every couple thousand miles, I'd probably just fabricate in some secondary fuel injectors to wash the valves down 1-2 times per drive cycle. Having to do this more than once (or at all) is insane.
Not sure about fuel but I have been reading about people fabricating Methanol injection just for the cleaning. Using the existing windshield washer bottle an winter windshield wash. They are saying the Methanol content is high enough. Food for thought 🤔
how about running couple cans of seafoam, would that help? I'm having random misfires on 2015 Sport w/139k miles, no permanent code. Check engine flashed once but nothing.
Do you know if anything has changed with the coking issue on modern Ecoboost engines that don't have dual injection? I've read some people say there are built in oil catch cans with EGR to handle it, and some say a valve reversion process. I can't believe after all this time only a handful of Ford engines address this with dual injection.
It’s ok as preventive Maintenance to use crc valve cleaner on my 2021 2.3 Ford explorer it has 11,500 miles, bought it with 5,000 miles and from there installed the oil catch can, using 5w-30 pennzoil ultra platinum.
I have a question. The problem with it is this. When I drive slowly from 0 - 100 there are no issues. But when I need to overtake and push the gas pedal, the wrench warning comes up, the vehicle jerks and slows down. Why do you think that is?
I've often wondered - we can cut thick steel with a high-pressure water jet. Why couldn't we use a lower pressure on a small hand squirter maybe not unlike what dentists use, to blast the carbon off? We could have a suction tube in there to suck up the water and debris. Or maybe just use the air tube.
I knew this could be done, everyone says you need to get it walnut blasted. I figured a little bit of time with brake clean and brushes and you could do this in your own driveway. I wonder if applying glyptal to the intake valves would be a viable solution for keeping oil deposits from ever sticking in the first place. I know people who have used that stuff inside crank cases to aid in return oil flow back to the sump, it creates a smooth non-stick surface inside the block.
I'm trying to do this on my 2016 Ford Fusion w/1.5L Turbo but It doesn't appear I have enough room toward the radiator fans to get the cooler and intake off. Is there a trick to getting the cooler out without taking the radiator and fans out?
Can carbon buildup on the valves cause pre-ignition/detonation? I’ve got 95k miles and an occasional misfire even after plug replacement. Also have some crazy pre-ignition/detonation between 2800 and 3200 rpm but at low throttle.
Does this apply to the 3.5L v6 ecoboost? I’ve been thinking about doing mine and installing a catch can. 120k on the clock, runs great but figured it’s probably pretty built up.
Look on line , you can order a small Borescope to plug into your phone. Can have a look yourself. they are surprisingly cheap. My F150 3.5 has 150k miles an after scoping it was time. Just a warning the back Cylinders at the fire wall require some stretching an creativity.. But I believe after 2015ish 2nd injectors were put in to correct the issue.
That job sure takes a deep cut into any gas $$$ saved. I have a 2021 Kia Forte 2.0 with GDI but i dont hear must about any Kia issues at least yet and my engine has been out for at least 3-4 years
Excellent thorough repair and video! Would you mind doing a tool box tour? Would be interesting to see what tools you mostly use to work on Ford vehicles.
Hello, my taurus 2000 radiator petcock starts slow leak and the petcock was Dorman Radiator Drain Cocks Part # 61127 installed a few years ago w/o issues. i replaced a new Part # 61127 but Still see the same issues. Do you have any suggestion?
Would pistachio shells work as well as walnut shells for cleaning? They seem as tough or tougher, plus theyre easy to make your own supply whilst snacking🙄
Order BG 44k immediately! I did. Great 1st start. Just add to fuel every few mos. Be sure to run a good < full synthetic > engine oil & change @5k mis max. Otherwise Ecoboost is phenomenal. My 3rd Ecoboost vehicle. Never issues! Im very religious bout oil changes & fuel quality! Pennzoil Platinum is awesome. Motul is best if ur wallets are deeper. - Ohio
I heard that some regular hard throttle can keep it from building up too bad. It's the easy city driving or mild highway use that causes a lot of build up. I'm nearing 100k on my F-150 and it's OK. Nearing 80k on the Escape that the wife putts around town in and I think it's going to look more like this video. It vibrates at 8dle a bit. But no code yet.
@@PsalmFourteenOne if I go too much past half throttle it will "stutter". Its at 55k and been doing that since around 20k. I'm afraid to take it in to have it checked. Just waiting for the right situation to trade it.
@@WarrenRCG Now you're afraid to have it checked, but at 20k it was covered under warranty. Depending on what year and model car you have, you may have gotten close to a new motor put in.
@@WarrenRCG A 4 cylinder ecoboost in a car? Our escape just vibrates at idle sometimes. Seems ok other than that. My F-150 still runs like a raped ape. I accelerate hard in it sometimes and drive it on the mountains so it probably heat cycles enough to cook that carbon off. It's a 2015. Our escape is a 2014. The new ones added port injection along with the GDI so they shouldn't have as much of the build up now.
Not trying to start a debate, but does a well designed catch prevent this? I have a '15 F150 with 2.7 (DI only) EcoBoost. Had 75,xxx miles with a catch can since around 20,xxx miles.
My wife’s 2013 escape 2.0 ecoboost idles rough but has no misfire count. 138,000 miles. Gets good MPG and runs fine other than a rough idle. Replaced motor mounts. Could this be a carbon issue? Uses no coolant
Its pretty much a buyer be aware issue. Be aware most Ford salesmen aren't going to tell you about GDI valve coking, and the dealer isn't going to do shit for induction service. If it doesn't throw a code, they ain't doing shit.
Thanks for the video. I've seen an older video where you used the walnut blasting method. Now you are back to manually cleaning. Is there any particular reason for that?
Here's a question for you. As a dealer tech (not ford) do you think this repair/maintenance should be a warranty based repair or CP? I've had many debates with my warranty admin regarding this and neither the dealer nor the manufacturer has an answer. Just wanted your opinion
CP. Carbon deposits are not defects in materials or workmanship. Warranty doesn't cover defects in the engineers' designs. That's why the manufacturers get sued and then offer "customer satisfaction" recalls...
Dang, I cant use my pressure washer ? LOL.......... anyway, thanks for this video. I used two cans of CRC and nothing really happened. But after I took off the intake and cleaned the valves like you have shown here, the #2 cylinder misfire went away.
So you do approve the use of BG induction cleaning say once a year 10-15k as a preventative maintenance measure ?? Obviously if there is build up already it’s best to do a manual cleaning correct ?
Hi I have a question, when you blow air through where the spark plugs are supposed to be in, to get any other deposits out, are you still leaving the valves closed or open?
So if it can happen at any mileage what use is this maintenance cleaning you talked about? I was going to ask if I ran or had my mechanic run the cleaning every forty thousand would that be good? Sounds like every twenty thousand I might just make it under the finish line.
I’m picking up my 2022 Bronco-2.7L on Tuesday. If I run Sunoco 93 Octane and Mobil 1 only, with that take care of the carbon buildup, or should I install a catch can? Never had a direct injected engine before.
For a Final Step: Scrub the valves manually with this-

I taped off one of the cyllinders cause that one is open i will now let it dwell for the night and see what it does, the ports toward the valve cleaned up very well so i have high hopes.
My catch can on my 2013 F-150 3.5 Ecoboost catches about 1/2 a Dixie-cup of syrupy, coffee consistency fluid between each oil change. Not sure how much build-up that saves on the valves, but at least I can attest to it catching some of the blow-by.
i have a carbon vac machine but with the intake desigs of todays cars the machine is not sufficent in cleaning the carbon off the valves. Renoving the intake on todays down draft intakes is the best way to get a good scrub on the intake valves. Also allows you to clean all the oil buildup from the pcv system in the intake by removal. Sea foam works good for me.
Would a catch can prevent the carbon buildup? If yes, what would you suggest for a 2.0L Lincoln Corsair?
Great info. Will a catch can help this issue any?
Yes it will
What’s a catch can..I’ve built Shelby 350s,500s,& Gt 40 engines the past 20+years and never heard of this term...thanks
@@FordTechMakuloco Is there a catch can you recommend for the 2016 3.5 ecoboost? My f150 has 42000 on it. Probably to late now 😂
@@FordTechMakuloco Would a 2016 F150 3.5L eco boost have this issue?
@@andrewrich6198 It can. It is a GDI engine. In 2017+ they switched to use both GDI and port injection, so the fuel should help keep the valves cleaner.
I have a 16 escape 1.6l that I have torn apart right now because it has all the symptoms of a bad pcv valve, to find out it doesn't have a pcv valve. It instead has an air oil separator. Have you ever had to replace one? And I figured while I had the intake off I would clean the valves because they were worse than the ones in video
PLEASE, I'm interested in what the injectors tip look like. Thanks
Future video coming.
Ditto!
do you by chance have a video of doing the same procedure but on the piston itself by removing the spark plug and adding something to it
Do you have a guide cleaning the values for 2017 ford Fiesta st?
I’ve got a Chevy v8 in my g8, I’m here just to see how your carbon cleaning goes lol I got injured, went a bit too long on an oil change and my pcv sucked in and coated up my intake lol baked on crap. It’s incredible since it’s not a direct injected engine.
If I were doing all this work to clean the intake valves every couple thousand miles, I'd probably just fabricate in some secondary fuel injectors to wash the valves down 1-2 times per drive cycle.
Having to do this more than once (or at all) is insane.
Not sure about fuel but I have been reading about people fabricating Methanol injection just for the cleaning. Using the existing windshield washer bottle an winter windshield wash. They are saying the Methanol content is high enough. Food for thought 🤔
@@thatguy3481 Thankfully I'll never run into this issue cause I have a port-injected 5.0, but that is an interesting idea. Thanks.
how about running couple cans of seafoam, would that help?
I'm having random misfires on 2015 Sport w/139k miles, no permanent code. Check engine flashed once but nothing.
Ever try using a tube brush with a drill for after you got the chunks off?
Do you know if anything has changed with the coking issue on modern Ecoboost engines that don't have dual injection? I've read some people say there are built in oil catch cans with EGR to handle it, and some say a valve reversion process.
I can't believe after all this time only a handful of Ford engines address this with dual injection.
thoughts on using a oil seperator or catch can to prevent this problem? would that help to prevent this build up?
Your opinion on catch cans for prevention? PCV side, Turbo side or both?
Thank uou
It’s ok as preventive Maintenance to use crc valve cleaner on my 2021 2.3 Ford explorer it has 11,500 miles, bought it with 5,000 miles and from there installed the oil catch can, using 5w-30 pennzoil ultra platinum.
An oil catch can kit can greatly reduce those service intervals,
Yup
He already has a great video showing how to install one😊
@@FordTechMakuloco will you put one on your new 2021? Or it is not needed?
@@FordTechMakuloco I wonder how many people just dump their catch cans down the drain?
Makes me happy my 12 Eco blew up and I got a 20 5.0.
I have a question. The problem with it is this.
When I drive slowly from 0 - 100 there are no issues. But when I need to overtake and push the gas pedal, the wrench warning comes up, the vehicle jerks and slows down.
Why do you think that is?
I've often wondered - we can cut thick steel with a high-pressure water jet. Why couldn't we use a lower pressure on a small hand squirter maybe not unlike what dentists use, to blast the carbon off? We could have a suction tube in there to suck up the water and debris. Or maybe just use the air tube.
What about walnut shells. Works better ??what do u think
It works well but it makes a huge mess
Yes but requires adapter and special tools, this is something any diyer can do.
I knew this could be done, everyone says you need to get it walnut blasted. I figured a little bit of time with brake clean and brushes and you could do this in your own driveway.
I wonder if applying glyptal to the intake valves would be a viable solution for keeping oil deposits from ever sticking in the first place. I know people who have used that stuff inside crank cases to aid in return oil flow back to the sump, it creates a smooth non-stick surface inside the block.
Good idea for a build you'd have to ultra clean each one and somehow bake it before use though, doesn't work to well unless.
91 and full synthetic +150k on my 2.0 awd 2013 Escape and no problems so far... changed plugs once about to again soon. Ngk or Denso's on all my stuff
I'm trying to do this on my 2016 Ford Fusion w/1.5L Turbo but It doesn't appear I have enough room toward the radiator fans to get the cooler and intake off. Is there a trick to getting the cooler out without taking the radiator and fans out?
Can carbon buildup on the valves cause pre-ignition/detonation? I’ve got 95k miles and an occasional misfire even after plug replacement. Also have some crazy pre-ignition/detonation between 2800 and 3200 rpm but at low throttle.
Does this apply to the 3.5L v6 ecoboost? I’ve been thinking about doing mine and installing a catch can. 120k on the clock, runs great but figured it’s probably pretty built up.
Look on line , you can order a small Borescope to plug into your phone. Can have a look yourself. they are surprisingly cheap. My F150 3.5 has 150k miles an after scoping it was time.
Just a warning the back Cylinders at the fire wall require some stretching an creativity..
But I believe after 2015ish 2nd injectors were put in to correct the issue.
Depends on the year of the vehicle. Port injection was added in 2017 models in addition to the direct injection on the 3.5 ecoboost.
@@thatguy3481 2018 2nd injectors put in for f150
Thanks for the info 👍
That job sure takes a deep cut into any gas $$$ saved. I have a 2021 Kia Forte 2.0 with GDI but i dont hear must about any Kia issues at least yet and my engine has been out for at least 3-4 years
How bout the 2.3 in the new rangers. Any big problems that you have seen. Thanks
Do you know if Ford Explorers 3.5 ecoboost have Port Fuel?
Could you make a video on how to remove the intake manifold?
Another great, educational video. THANK YOU!!!!!
Excellent thorough repair and video! Would you mind doing a tool box tour? Would be interesting to see what tools you mostly use to work on Ford vehicles.
I plan on doing the manual cleaning method. I know BG makes great chemicals, but I don't want to run that stuff through my cats.
Have you found this issue to be present on the Ranger’s 2.3, the same long block as the Mustang GT and Focus RS?
Hello, my taurus 2000 radiator petcock starts slow leak and the petcock was Dorman Radiator Drain Cocks Part # 61127 installed a few years ago w/o issues. i replaced a new Part # 61127 but Still see the same issues. Do you have any suggestion?
Would pistachio shells work as well as walnut shells for cleaning? They seem as tough or tougher, plus theyre easy to make your own supply whilst snacking🙄
I will happily ship out pistachio shells to anyone, free of change, just send it and get a return on it too lol.
at least the intake is facing the front on engine
Underrated comment, lol
Have u done a walnut blasting service on ecoboost
Do you have any fiesta videos? Where the heck is the tpms receiver located.
Does using top tier gas help reduce this carbon buildup?
Perfect! Great video! I've used those intake cleaners like I v system too. Don't work so well! This a for sure way to clean the valves!
I know the new 3.5 ecoboost f-150 has direct injection with the old school port injection to keep the intake washed out with fuel. Better system.
Weird. I was just researching this yesterday. Good timing!
Order BG 44k immediately! I did. Great 1st start. Just add to fuel every few mos. Be sure to run a good < full synthetic > engine oil & change @5k mis max. Otherwise Ecoboost is phenomenal. My 3rd Ecoboost vehicle. Never issues! Im very religious bout oil changes & fuel quality! Pennzoil Platinum is awesome. Motul is best if ur wallets are deeper. - Ohio
So how do you know if my ecoboost has port fuel? I bought my Explorer 3.5 ecoboost in March 2018...
Looking to do this on my '18 Focus ST, thanks for the video!
Whats your opinion on catch cans for the oily pcv recirculation causing this?
He has a vid and recommends rx can which he put on his ecoboost I believe
Great video! But it makes me sick knowing my EcoBoost is getting crusty. 🙈
I heard that some regular hard throttle can keep it from building up too bad.
It's the easy city driving or mild highway use that causes a lot of build up.
I'm nearing 100k on my F-150 and it's OK.
Nearing 80k on the Escape that the wife putts around town in and I think it's going to look more like this video.
It vibrates at 8dle a bit.
But no code yet.
@@PsalmFourteenOne if I go too much past half throttle it will "stutter". Its at 55k and been doing that since around 20k. I'm afraid to take it in to have it checked. Just waiting for the right situation to trade it.
@@WarrenRCG Now you're afraid to have it checked, but at 20k it was covered under warranty. Depending on what year and model car you have, you may have gotten close to a new motor put in.
@@WarrenRCG A 4 cylinder ecoboost in a car?
Our escape just vibrates at idle sometimes. Seems ok other than that.
My F-150 still runs like a raped ape.
I accelerate hard in it sometimes and drive it on the mountains so it probably heat cycles enough to cook that carbon off.
It's a 2015. Our escape is a 2014.
The new ones added port injection along with the GDI so they shouldn't have as much of the build up now.
@@PsalmFourteenOne 2015 Escape 2.0l 4WD I hardly drive anymore since I work from home now. Averaging 30 miles per week. It's got plenty of life left.
Does the valve blockage ever manifest as negative LT or ST trims in a scan tool?
yes
I have seen LT trims of neg 18 on cars with less than 50k.
Not trying to start a debate, but does a well designed catch prevent this?
I have a '15 F150 with 2.7 (DI only) EcoBoost. Had 75,xxx miles with a catch can since around 20,xxx miles.
My wife’s 2013 escape 2.0 ecoboost idles rough but has no misfire count. 138,000 miles. Gets good MPG and runs fine other than a rough idle. Replaced motor mounts. Could this be a carbon issue? Uses no coolant
People need to be made aware of this issue when they buy these vehicles new. I can't imagine explaining this to my coustomers
I'm sure the sale man tying to sell you that new car will let you know about the carbon build up issues
Its pretty much a buyer be aware issue. Be aware most Ford salesmen aren't going to tell you about GDI valve coking, and the dealer isn't going to do shit for induction service. If it doesn't throw a code, they ain't doing shit.
And they put them on the market without a plan to remedy the problem for years and years.
Orileys brand brake clean knocks that gunk out really well. Of course some scrubbing is needed here and there
Thanks for the video. I've seen an older video where you used the walnut blasting method. Now you are back to manually cleaning. Is there any particular reason for that?
Do you recommend any oil catch-can for the 2.0 Eco for an MKZ and what kind?
Here's a question for you. As a dealer tech (not ford) do you think this repair/maintenance should be a warranty based repair or CP? I've had many debates with my warranty admin regarding this and neither the dealer nor the manufacturer has an answer. Just wanted your opinion
CP. Carbon deposits are not defects in materials or workmanship.
Warranty doesn't cover defects in the engineers' designs. That's why the manufacturers get sued and then offer "customer satisfaction" recalls...
No warranty it’s just maintenance.
Dang, I cant use my pressure washer ?
LOL.......... anyway, thanks for this video. I used two cans of CRC and nothing really happened. But after I took off the intake and cleaned the valves like you have shown here, the #2 cylinder misfire went away.
So you do approve the use of BG induction cleaning say once a year 10-15k as a preventative maintenance measure ?? Obviously if there is build up already it’s best to do a manual cleaning correct ?
It works but honestly a walnuts blasting is way better for the engine
Is there a Part # for that BG Kit of chems?
Hi I have a question, when you blow air through where the spark plugs are supposed to be in, to get any other deposits out, are you still leaving the valves closed or open?
What about the V6 mustang 2017 is it the same ?
Focus is out of focus, at least it's not trying to Escape. (Crappy joke, one of them days. 😏)
Ok, you get your ass outta here!! (Saying this in a joking way)
@Ben C You need to see yourself out to sir. Lmao!!!
no trying to Escape just went to Explorer but she finds herself on an Expedition
Once he's done cleaning and job is done we can have a little Fiesta 😏
Someones gonna have to Escort you outta here.. not tryna Flex but its a must
Brian, I want to do CRC valve cleaning spray. Do you know where is the brake boos vaccum line in my 2018 explorer 3.5 ecoboost?
So if it can happen at any mileage what use is this maintenance cleaning you talked about? I was going to ask if I ran or had my mechanic run the cleaning every forty thousand would that be good? Sounds like every twenty thousand I might just make it under the finish line.
My explorer was an extreme case I would say every 40-60k would keep any drivability concerns at bay.
I’m picking up my 2022 Bronco-2.7L on Tuesday. If I run Sunoco 93 Octane and Mobil 1 only, with that take care of the carbon buildup, or should I install a catch can? Never had a direct injected engine before.
This is why i love my 383 stroker
