All knowledge is a gift. You really need to look into opening your own shop, & having technicians work for you. ALOT of the information you know by memory is VERY VERY delicate, your doing a tremendous favor in explaining this information because its in a sense that anyone can comprehend.

I am new to the world of Cat C7 engines. I am a shop owner and have worked in the gas engine and limited diesel for over 35 years. Recently purchased a RV with a C7 engine with 25 K miles. Thought well I had best start educating myself for whats down the road. I have watched several of your videos today and gained a great deal from them. Just wanted to say thanks and keep up the good work.

Love the channel, 06 c7 435,000 miles , no blow by or none noticeable, but at idle oil pressure is 20-25 psi according to gauge running down the road 45-55 psi . 6 spd manual , seems to loose power with modest gvw of 32k at any slight hill . Was told injectors may be leaking oil. No noticeable smoke from Exhust
i like how you went threw step by step with everything. covered everything. its good to have someone go more in depth than Kilmer. nice video brother. But get some coffee lol. speed it up a bit add some flare!
One more thing causes low oil pressure? check oil transfer, may be transmission or hydraulic oil due to bad seal, at this time the viscosity will be low and increase oil engine level.
I have 2005 c7 cold engine oil pressure around 50 after engine hits it drops to around 25lbs at 70mph and hits as low as 15 or 20lbs at idle , but it does have 700k miles so I’m gonna figure she’s about to life expectancy especially since she has a decent amount of blow by and loves to paint the undercarriage of soot but I’d buy 10 more just like her. 05 freightliner box truck 1.3 million miles second engine 4th owner

My c13 is getting check engine light and i hooked a computer to it and its saying low oil pressure. Just a few days ago the truck would give a jerking feeling and now it doesnt run over 15 mph without cutting off. The truck would stay on while idling but if i move itll just cut off. Any idea
Very informative video. I'm the chief of a small rural fire department and we got a 2003 Stewart Stevenson M1078 granted to us by the feds, 8000 miles, 500 hours. Kenworth replaced a sensor on it and the darn thing wasn't tightened down properly and spewed most of the oil out before we noticed it. We got it to a truck stop, they tightened the sensor, put in new oil and everything seemed fine, drove it 60 miles through some mountains, then suddenly and ongoing it has a fluctuating oil pressure between 25-40 under 30mph but if you ask for any torque or speed above 30mph the pressure drops almost immediately to zero and the motor goes into limp. Kenworth can't figure it out but they suspect there might be something in the oil pan or the uptake tube is busted off or something.. Any other suggestions??
Got a Detroit dd13 oil temperature wanting to run higher then normal up about 25 degrees higher and oil pressure running lower then normal,thinking oil cooler?
👍 I enjoyed your video I have a C 16 caterpillar 600 hp that we just rebuilt 57,000 miles ago I have low oil pressure idling 11 pounds 1500 rpm’s 27 pounds we have change Oil pump check the oilers changed oil filters changed oil sensors and my old pressure is still the same any ideas would be deeply appreciated Is there a difference between a C 15 oil pump and a C 16 oil pump Is there a higher pressure oil pump with that help ?
Really you are a great man Can you tell me please how much does a range of normal pressure oil pressure for c18 and normal w pressure at idle speed and 1500 RPM
Great video. I am having an issue with my trucks oil pressure changing from day to day on my N14?? I got low oil pressure one day. I replaced the oil pump out thinking it was bad. Turns out a piston cooling nozzle cracked. It was replaceable from outside the engine so I changed it. Everything back to normal Two weeks later low oil pressure out of nowhere while driving (after about 3 hours of driving that day at normal levels). Tow the truck home, check nozzles all good. Check the oil relief valve and it seems to be fine. Truck randomly gains oil pressure again after letting it sit for a few days and restarting it. I replaced the oil pressure sensor as well just in case. I drive it on a small job everything is fine and running at 28 psi under load and 10 at idle. Wake up the next day and it idles at 10 psi cold and throws a “check fluids light” at 1500 rpm because the motor struggles to get 20 psi pressure (cold at 1500rpm). Me and my mechanics are so confused. The pressure keeps changing from day to day. I guess it time to drop the pan and see if anything is blocking the oil intake? The pressure changes random and quickly.
Total solution = Collapsed Oil Filter {more than likely a Baldwin Oil Filter} just change oil filters. Other possibilities, oil pressure sensor or oil pump... which is basically 2 metal gears that rarely fail.
Thank you for all the helpful explanations, I love your videos. I have an old 93 model flat top with a 3406C converted to a B(4ck). I’ve always had about 55 running hot on the highway, and just last year, it dropped to 45-50. I got an overhaul and replaced everything but the block and it’s still at 45-50 running down the highway. I was told that the front and rear seals and cam bearings can affect the pressure too, I haven’t done that yet. Is that true?
11:31 my C13 2006 Peterbilt has low oil pressure 18 idle and 20 on the road?? Had this this problem before changed release valve pressure went up to 40-50 while driving now it went back down to 20
My oil pressure is at 45psi on a cold start but after driving it for a few hrs it drops to abt 10psi when I first got the car 4 yrs ago oil pressure was on 50 60 cold start and idle on its 20s and it stayed ther ... I’m going to assume as long as I have oil pressure while I drive it should be ok but how low is too low for the high way ? I was at 37psi at 80mph today I remember seeing at least 60psi duing 120pmh on the highway lol not anymore
Hey Josh! I have a mbn c15 with 1,265,000 miles and just shy of 40,xxx hours.. Under boost my oil pressure drops between 8-10 psi.. Could this be because of lower end bearing clearance? Motor has never been rebuilt and has original head..
The idle oil pressure on my recently rebuilt marine cat 3208 is 75psi initially, drops to 25psi when warmed up, and down to 12psi when in gear. It goes back to 25-35psi at 2000rpm. Any ideas?
I just did my oils changed and I noticed it’s oil on my front bumper it’s likely steam spots but I couldn’t find any major oil leaking, and oil pressure it’s normal at 40 to 60 do you knows anything about it, ??
John Torres I have c7 -190 hp -2006 straight truck . I have fuel in oil cause low oil pressure . Fuel injectors look ok too. Do u know any other thing that make this problem? No code or sensor light so far . Waiting
Taljinder singh gill After checked by cat dealer, found #5th injectors need to replace. I spent 2500$ with peterbilt dealer and they just changed o rings .....and told me all good to go with out checking again with dye.
I have seen jake brake O rings left out by a DIYer causing lower than normal oil pressure. Knowing engine history can be a huge troubleshooting benefit.
I’ve recently bought a Porsche 987 to find out I was also lied to. Doing a test drive didn’t reveal any problems, but a flat tire in the rear did so it was a short ride. No lights on the dashboard, but the battery was also something wrong with. After putting it on a trailer to get it home I had to replace the battery to get it working again. After this I started to notice all the lights on my dash to lit up like a Christmas tree. I’ve read this might be a result of the battery change, but I’m thinking it’s not. Letting it run idle for 15mins the one thing that worried me the most was: ‘oil pressure too low’. Than I saw my cooling cap with hot boiling water and steam trying to get out! I didn’t open it with the water cooking but I’m worried there might be some mayonnaise in it. Suggests blown head gasket. I have to be sure of course but this might be the reason of the low oil pressure I assume. Question: is there anything to fix it immediately so I can drive the car to the garage? Is it dangerous? Can I just add more oil or water/coolant? I don’t want to get the engine blown, but I need to get it out of my parking underneath the building first in case of towing it. Just wondering how dangerous it is or what I should do. I’m just looking for the least amount of costs.
I got a 97 Mitsubishi Eclipse GST with a 4g63 T turbo engine was running fine pulling boost at 3rd gear 15 lb oil gauge dropped all the way down. I'm new to this engine and I'm trying to find where to put the pressure tester on my engine. HELP I'm afraid to start up my car if it's not pumping oil through my engine I don't want to blow my engine
Hi I’m a first time watcher I have a problem with my 2007 f350 super duty when I’m driving without the a/c it’s fine but when I turn it on and slow down to first gear under 2,000 rpm I get low oil pressure I don’t know why?
We had a similar problem with our Cummins N-8-G2 180 KVA Genset engine. All the valve springs broke off and one exhaust valve broke, hit the piston and was stuck in the head. Some broken parts found their way into the turbo and ate the turbine wheel.There was also diesel in the coolant and one bent push rod. The head had to be replaced and the whole engine rebuilt.
I have a c13 with about 1067000 miles. My jakes or rpm gauge aren't working. I also have oil in my coolant. Any idea what would cause the jakes or rpm gauge not to work and the oil in coolant? Thanks
Quick question I have two C-15 and on both trucks I have active a BAROMETRIC PRESSURE its possible the censor has to be replaced or what that means or it signal the something really bad is coming??
My oil pressure dropped 10 pounds usually runs at 35 it’s down to 22 2325 I do have coolant in my oil I do know that is sending it out some and I try to keep changing it out every two days tomorrow I’m going to drop my pan drop change my oil out and have a look at my pump because my engine does have 1,000,000+ kilometers on it 1,000,001 km on it it’s stressful running down the road but going to try and make it do for a little while longer
I have a 2006 c7. The oil and check engine light are on. Alarm beeping. 45psi oil press at idle cold and after warm up going down the highway it stays at like 30-35.
Please help, I have 2009 ISX CM871 ,my oil pressure drops on probably every 3-4k miles, i change new oil filter, goes back to normal, please help if possible, thanks in advance.
Please help! I have cummins isx 485 oil pressure low but after change oil filter it is normal...i frequently change oil filter every about 900 miles to fix the oil pressure ? What is the cause of this...thanks in advance.
I have a bxs engine had 40psi at idle and 70 psi at at higher rpm before rebuilt. I rebuilt it a couple of months ago with idp parts and it's been 32psi at idling and 62 at higher rpm any ideas?
I have a cat c7 normal oil pressure is above 50 but after awhile it drops below 40 then easy up slightly and then after a while it jumps above 50 then falls back down what you think
Hello, i have a newly out of frame rebuild c15 acert nxs and it has low oil pressure. Starts of at 60 when first start it then goes down to 10 ! Cat told me to run it hard so the rings will be seated and then it will run fine after a while. The problem is that when i take it out to drive it, i lose power and once even shut down on me just few miles from the yard! I waited about 20 min then got it to the yard which it was about 3 miles maybe less away. Left it running and took the dip stick off and was spitting out oil!!! I called cat and they said it can be crank case pressure but i feel that’s too many things happening on a platinum rebuilt?! What you think?
Can you please make some videos for Detroit 60 series. I very like glider kit D-60 12,7 & 14 L but I need professional recommendation of this engine with freightliner Coronado afeter. 2015 So much thanks to you.
Could you explain oil pressure going up dramatically. Used to drop down to 40 psi at an idle but now it never stops below 60 and goes up to 85 psi, which engine has never done before.
Have an 07 MXS, hot oil pressure will get to 15-16psi at idle, and at 1500 rpms it only makes about 50psi. From everything I've seen it should be closer to the 40ish psi range at hot idle. This is a company truck that is new to me, 1,543,000 miles, no clue if it has been rebuilt at all. seems to run fine and pull fine, currently has codes 95 and 98 though, which I will hopefully get fixed soon. oil was changed just under 3000 miles ago with a baldwin filter. it doesn't seem to make oil or mix oil/coolant. I plan to put a mechanical gauge on it and verify, but the Jake's don't work very well either so I plan to take the valve covers off and check out everything up top and do an overhead. any other suggestions?
Hey man new to your channel but I have a C10 that has a lot of pressure building up in crank case and is causing oil to shoot out of the dip stick tube and then shutting the truck down for low oil pressure which is understandable being as though it just dumped all of the oil.
Have you figured out the issue? I am having the same problem on my c15 but mine is a platinum rebuilt and still have warranty for another 2 and half years, but if it’s something simple i don’t wanna take it in idk!
I have a c15 mxs at operating temp at 600 rpm oil pressure is 30-35 psi, 1000 rpm 50psi, and at 1500 rpm is 55psi. I did notice my oil pressure sensor is leaking around the bottom. If the oring is that bad I would imagine the sensor isn’t the most accurate. The engine has 1.4 million and had a rebuild at 1million. I will put my manual oil pressure gauge after work but just wanted to see your thoughts.
I have absolutely no oil pressure at the gauge bought the motor home in Texas drove almost two thousand miles the gauge stayed on zero like it is not hooked up any suggestions
I have a 02 mack Vision that the oil gear pump blew up in mack told me to rebuild it would be $30.000 took off the pan see not to much wrong so I just ordered a new oil pump hoping this will work the guy driving said the check engine light came on loss of oil pressure truck shut off
I just looked it up to verify your specific serial number should be on the engine block in front of the ECM on the driver side/left side of the engine connected to the same fitting the air compressor oil line is connected to.
Kubota V1100 diesel in a mower has good oil pressure on start up, but as the engine warms up the oil pressure steadily drops (50psi at start up to 18psi after a 45 minutes). It does this even after an oil change. Mechanical oil pressure gauge, temp runs up to 200. Any ideas?
We have a C15 ACERT MXS series engine that was showing low oil pressure and shut down. Towed it to a shop. They said it was showing 35 - 40 PSI and should be 75 PSI on a cold start. ECU showed at one point it was in the 20 PSI range. They took the pan off to inspect and said that the bearings look good, but there's "No cross marking in the liners. Liners are glazed." They want to do an in-frame to the tune of $18,500. We had an IVA #1 code as well before all this happened. I can't find much help on this engine as far as cross marking and low oil pressure. There's only 55,000 miles on the engine, it's a 2007. Does this sound right? They didn't pull the head to inspect the cylinders.
Thanks for taking the time and effort to share your knowledge. Neither my son nor I are professional mechanics but we prefer to do our maintenance (preventative and corrective) when we feel competent in doing so. You have helped. He has a 3128 in a marine application and I have a C-7 in a motorhome.Since the engine in a motorhome is installed with the front facing aft I assume your references to left side/right side or driver side is reversed in the motorhome application. I belong to a large motorhome based group (Fleetwood Discovery) with a large number of existing CAT powered units and will encourage the membership to subscribe- if for no other then reason then to be able to talk about a problem intelligently.
+tom ferrara Thank you for the support, tell them to subscribe please, it really helps the channel grow. Alright so for the jargon on the RV engine, on an engine the left side is always in relation to facing from the rear of the engine looking towards the front of the engine so the left side is always the same side, but you are correct that it would now be the passenger side since your engine is facing with the front towards the rear of your rig. I should have just said the intake side, would've made more sense.
if you don't see me comment on his vids about something said wrong you can assume that its100% accurate as I only subscribe to people with professional accurate content my self.
Thanks for that detailed info on oil pressure problems. In my case The old pressure starts at 90 psi and after about a half hour of idle drops below 30 psi on the starboard engine the port engine settles up at 60 psi at idle what would cause the starboard engine oil pressure to slowly diminish like that. The difference between the port engine and the starboard engine after a half hour of idling is like 30 psi. I’d appreciate some direction where I should start looking thank you
Great video thanks very informative I want to ask I have cat c7 2005 my oil pressure when Engine is hot is around 25-28 psi is that normal or it’s low oil pressure???
I learned a lot about this engine already in your videos. Thank You. But I still have a question, just please give me an opinion here. So I'm very close to buy a 1997 Tiffing Allegro Bus. It's a pusher and has a CAT 3127. I inspected and test drove on a super steep mountain. Everything works good. Temps are normal. Exhaust brakes work, has allison tranny. My only concern is the oil pressure gauge is barely staying in the green. As I accelerate is goes up just a bit. But it's not jumping. Blowby is minimum, oil clean, coolant clean, all systems read no fails in the computer. Question is could it be just the gauge or sender? Is that common issue, ... the chassis is freigthliner., is it a high risk of getting a worn out engine/bearings.? It only has 53k miles. Priced at 18k... coach is fair. Kindly tell me your opinion and what you have seen out there as I know you touch lots of rv s. Take care, and great job.
Are you a. Expert in maxxforce engine have 2013 international giving be issued as to when I’m driving it just shut off. On the highway is fine but on the road it shut off unexpectedly? They claim low fuel pressure. It can be my ecm .. but when it shut off. I remove the cables from batteries then put it back it restarted again to drive.. help ? I my work horse. And putting me outta work..
I used to my car an oil filter (STP) it's easy to clog this filter for 2 moths only.That's pretty bad this product but know I learn a lesson .I never used again this oil filter is made in China.
Hi am using c9 engine now days I have low lub oil pr.low I don't have fuel contamination After changing filter and oil I have 3.2 bar My other generators are 3.7 after filter and oil change Now the problem is with in 250 running hrs the pressure drops gradually to 2.5 bar alarm level Could u help me what could be the reason for this?
Hey man I have a Audi A4 2011 74,000 and the low oil pressure came on. I already changed the oil filter, changed the oil, the oil pressure switches. What else could it be? Help
I have a c15 acert my oil pressure at 185 water temperature idling is at 30psi and running at 60psi when temperature goes 205 the pressure goes down to 58pis it cools down and goes back to 60 psi should I be worried about my oil pressure also whats the normal oil pressure on c15 Acer???
OK truck smokes on fire up? normal idle smokes for 4 to 5 minutes. higher idle 900 only for two minutes. truck runs great all day long plenty of power. number 4 injector went bad changed, still smoking. done injector cut out number 4 smoke goes away. what do you think? 3406E 1LW
+Joshua5869 Kubo Sounds like you did some good troubleshooting so far and isolating it to cylinder 4. Alright well if you changed the injector and you still have smoke then it is something mechanical, now don't panic yet as it could be something non major. The overhead for number 4 cylinder needs inspected carefully, you could have a rocker arm or cam lobe failing. The Jake can also stick which would keep your exhaust valve slightly open at all times, which can result in that as well, if you suspect the Jake you can look to see if it is further out than the other Jake's or swap the Jake housings with another cylinders like 1-2 and 3-4, or back the adjuster off. Check your valve adjustment as well. Now if all of that looks good then that pretty much leaves the cylinder/piston/valves. So the head would have to come off. You can also pull the oil pan to inspect the cylinder walls, or do a leak down test with a rubber tipped air nozzle to see if that cylinder holds air properly. Hope that helps.

Will engine replacement fix low oil pressure?.....whatever the cause was
My c13 is getting check engine light and i hooked a computer to it and its saying low oil pressure. Just a few days ago the truck would give a jerking feeling and now it doesnt run over 15 mph without cutting off. The truck would stay on while idling but if i move itll just cut off. Any idea
Great information but what is considered low oil pressure while cranking?? at the base oil pressure on a cat C7??

Rod and main bearings. Can even be cam bearings
Can it be an electrical issue not sending to sensors?
Thank you for all the helpful explanations, I love your videos. I have an old 93 model flat top with a 3406C converted to a B(4ck).

Hey Josh! I have a mbn c15 with 1,265,000 miles and just shy of 40,xxx hours.. Under boost my oil pressure drops between 8-10 psi.. Could this be because of lower end bearing clearance? Motor has never been rebuilt and has original head..
The idle oil pressure on my recently rebuilt marine cat 3208 is 75psi initially, drops to 25psi when warmed up, and down to 12psi when in gear. It goes back to 25-35psi at 2000rpm. Any ideas?
I just did my oils changed and I noticed it’s oil on my front bumper it’s likely steam spots but I couldn’t find any major oil leaking, and oil pressure it’s normal at 40 to 60 do you knows anything about it, ??

After checked by cat dealer, found #5th injectors need to replace.
I spent 2500$ with peterbilt dealer and they just changed o rings .....and told me all good to go with out checking again with dye.
my jobs truck is at 20 psi and idles at 2 psi on here trying to educate myself because the jokers I work for don't give a f
I have seen jake brake O rings left out by a DIYer causing lower than normal oil pressure. Knowing engine history can be a huge troubleshooting benefit.
Can adding a thicker oil bring the oil pressure up more ?
Hello i buy a 2005 kenworth w c13 cat 430hp and oil pressure is 40 idle w is hot and about 65 in 1500 rpm is normal???
I’ve recently bought a Porsche 987 to find out I was also lied to. Doing a test drive didn’t reveal any problems, but a flat tire in the rear did so it was a short ride. No lights on the dashboard, but the battery was also something wrong with. After putting it on a trailer to get it home I had to replace the battery to get it working again. After this I started to notice all the lights on my dash to lit up like a Christmas tree. I’ve read this might be a result of the battery change, but I’m thinking it’s not. Letting it run idle for 15mins the one thing that worried me the most was: ‘oil pressure too low’. Than I saw my cooling cap with hot boiling water and steam trying to get out! I didn’t open it with the water cooking but I’m worried there might be some mayonnaise in it. Suggests blown head gasket. I have to be sure of course but this might be the reason of the low oil pressure I assume. Question: is there anything to fix it immediately so I can drive the car to the garage? Is it dangerous? Can I just add more oil or water/coolant? I don’t want to get the engine blown, but I need to get it out of my parking underneath the building first in case of towing it. Just wondering how dangerous it is or what I should do. I’m just looking for the least amount of costs.
6.5l diesel hot idling 18 to 15 psi oil pressure is this ok or bad she runs 45 to 50 driving
I got a 97 Mitsubishi Eclipse GST with a 4g63 T turbo engine was running fine pulling boost at 3rd gear 15 lb oil gauge dropped all the way down. I'm new to this engine and I'm trying to find where to put the pressure tester on my engine. HELP I'm afraid to start up my car if it's not pumping oil through my engine I don't want to blow my engine
Hi I’m a first time watcher I have a problem with my 2007 f350 super duty when I’m driving without the a/c it’s fine but when I turn it on and slow down to first gear under 2,000 rpm I get low oil pressure I don’t know why?
Do you have a video for low oil pressure only at idle?
We had a similar problem with our Cummins N-8-G2 180 KVA Genset engine. All the valve springs broke off and one exhaust valve broke, hit the piston and was stuck in the head. Some broken parts found their way into the turbo and ate the turbine wheel.There was also diesel in the coolant and one bent push rod. The head had to be replaced and the whole engine rebuilt.
I have a c13 with about 1067000 miles. My jakes or rpm gauge aren't working. I also have oil in my coolant. Any idea what would cause the jakes or rpm gauge not to work and the oil in coolant? Thanks
What if your oil light blinks on and off while driving
Strainer on a diesel cause ??
Quick question I have two C-15 and on both trucks I have active a BAROMETRIC PRESSURE its possible the censor has to be replaced or what that means or it signal the something really bad is coming??
My oil pressure dropped 10 pounds usually runs at 35 it’s down to 22 2325 I do have coolant in my oil I do know that is sending it out some and I try to keep changing it out every two days tomorrow I’m going to drop my pan drop change my oil out and have a look at my pump because my engine does have 1,000,000+ kilometers on it 1,000,001 km on it it’s stressful running down the road but going to try and make it do for a little while longer
I have a 2006 c7. The oil and check engine light are on. Alarm beeping. 45psi oil press at idle cold and after warm up going down the highway it stays at like 30-35.
Please help, I have 2009 ISX CM871 ,my oil pressure drops on probably every 3-4k miles, i change new oil filter, goes back to normal, please help if possible, thanks in advance.
i have low presure oil & engine stop
can i drive my car ?
Please help! I have cummins isx 485 oil pressure low but after change oil filter it is normal...i frequently change oil filter every about 900 miles to fix the oil pressure ? What is the cause of this...thanks in advance.
I have a bxs engine had 40psi at idle and 70 psi at at higher rpm before rebuilt. I rebuilt it a couple of months ago with idp parts and it's been 32psi at idling and 62 at higher rpm any ideas?
I have a cat c7 normal oil pressure is above 50 but after awhile it drops below 40 then easy up slightly and then after a while it jumps above 50 then falls back down what you think
Hello, i have a newly out of frame rebuild c15 acert nxs and it has low oil pressure. Starts of at 60 when first start it then goes down to 10 ! Cat told me to run it hard so the rings will be seated and then it will run fine after a while. The problem is that when i take it out to drive it, i lose power and once even shut down on me just few miles from the yard! I waited about 20 min then got it to the yard which it was about 3 miles maybe less away. Left it running and took the dip stick off and was spitting out oil!!! I called cat and they said it can be crank case pressure but i feel that’s too many things happening on a platinum rebuilt?! What you think?
C7 oil pressure after it get hot ( operating temp) oil pressure its around 16-18psi
How about oil leaks from oil pan? Does it cause low oil pressure?
Yes
Can you please make some videos for Detroit 60 series. I very like glider kit D-60 12,7 & 14 L but I need professional recommendation of this engine with freightliner Coronado afeter. 2015 So much thanks to you.
Could you explain oil pressure going up dramatically. Used to drop down to 40 psi at an idle but now it never stops below 60 and goes up to 85 psi, which engine has never done before.
My C7 Cat 2004 89k in RV is at 26psi idle and 32psi at freeway speeds. Any reason for alarm. Thanks for the great videos.
Check the oil when it’s hot or cold?
Have an 07 MXS, hot oil pressure will get to 15-16psi at idle, and at 1500 rpms it only makes about 50psi. From everything I've seen it should be closer to the 40ish psi range at hot idle. This is a company truck that is new to me, 1,543,000 miles, no clue if it has been rebuilt at all. seems to run fine and pull fine, currently has codes 95 and 98 though, which I will hopefully get fixed soon. oil was changed just under 3000 miles ago with a baldwin filter. it doesn't seem to make oil or mix oil/coolant. I plan to put a mechanical gauge on it and verify, but the Jake's don't work very well either so I plan to take the valve covers off and check out everything up top and do an overhead. any other suggestions?
Hey man new to your channel but I have a C10 that has a lot of pressure building up in crank case and is causing oil to shoot out of the dip stick tube and then shutting the truck down for low oil pressure which is understandable being as though it just dumped all of the oil.
Have you figured out the issue? I am having the same problem on my c15 but mine is a platinum rebuilt and still have warranty for another 2 and half years, but if it’s something simple i don’t wanna take it in idk!
This will require an overhaul.
I have a c15 mxs at operating temp at 600 rpm oil pressure is 30-35 psi, 1000 rpm 50psi, and at 1500 rpm is 55psi. I did notice my oil pressure sensor is leaking around the bottom. If the oring is that bad I would imagine the sensor isn’t the most accurate. The engine has 1.4 million and had a rebuild at 1million. I will put my manual oil pressure gauge after work but just wanted to see your thoughts.
Few day ago, in toyota camery is 2008 showing pressure oil indication. It some time come and disappear. Please give me advice what should I do?
I have absolutely no oil pressure at the gauge bought the motor home in Texas drove almost two thousand miles the gauge stayed on zero like it is not hooked up any suggestions
I have a 02 mack Vision that the oil gear pump blew up in mack told me to rebuild it would be $30.000 took off the pan see not to much wrong so I just ordered a new oil pump hoping this will work the guy driving said the check engine light came on loss of oil pressure truck shut off
Need some assistance. I cannot locate the oil pressure sensor on my c12- serial#2KS95042.
I just looked it up to verify your specific serial number should be on the engine block in front of the ECM on the driver side/left side of the engine connected to the same fitting the air compressor oil line is connected to.
Kubota V1100 diesel in a mower has good oil pressure on start up, but as the engine warms up the oil pressure steadily drops (50psi at start up to 18psi after a 45 minutes). It does this even after an oil change. Mechanical oil pressure gauge, temp runs up to 200. Any ideas?
I have a 2002 mack vision starts runs for a minute then shut's off because it's not reading oil pressure can you give me any advice please?
We have a C15 ACERT MXS series engine that was showing low oil pressure and shut down. Towed it to a shop. They said it was showing 35 - 40 PSI and should be 75 PSI on a cold start. ECU showed at one point it was in the 20 PSI range. They took the pan off to inspect and said that the bearings look good, but there's "No cross marking in the liners. Liners are glazed." They want to do an in-frame to the tune of $18,500. We had an IVA #1 code as well before all this happened. I can't find much help on this engine as far as cross marking and low oil pressure. There's only 55,000 miles on the engine, it's a 2007. Does this sound right? They didn't pull the head to inspect the cylinders.
My oil pressure on my 3126 it as 150/200 KPA at 2000rpm and stable in my oil pressure level driving board , does I should worry about ?
Wow. You are a amazing at teaching and explaining. Loved the video . New subscriber here!
I have a 95 3406E when warm up , PSI is 20 is this normal? What can happen?
Can you please share the picture of oil pressure relief valve and the location too.
Thanks
Thanks for taking the time and effort to share your knowledge. Neither my son nor I are professional mechanics but we prefer to do our maintenance (preventative and corrective) when we feel competent in doing so. You have helped. He has a 3128 in a marine application and I have a C-7 in a motorhome.Since the engine in a motorhome is installed with the front facing aft I assume your references to left side/right side or driver side is reversed in the motorhome application. I belong to a large motorhome based group (Fleetwood Discovery) with a large number of existing CAT powered units and will encourage the membership to subscribe- if for no other then reason then to be able to talk about a problem intelligently.
+tom ferrara Thank you for the support, tell them to subscribe please, it really helps the channel grow. Alright so for the jargon on the RV engine, on an engine the left side is always in relation to facing from the rear of the engine looking towards the front of the engine so the left side is always the same side, but you are correct that it would now be the passenger side since your engine is facing with the front towards the rear of your rig. I should have just said the intake side, would've made more sense.
if you don't see me comment on his vids about something said wrong you can assume that its100% accurate as I only subscribe to people with professional accurate content my self.
I hope I have your subscription then. Not to say I'm never wrong, just try to tell information that is correct and vetted.
yes you are on my small list and no one can know everything it's why we can comment to point at potential wrong information and talk about it.
+Intrade Motor I appreciate that. I don't mind hearing new information when it's out.
Thanks for that detailed info on oil pressure problems. In my case The old pressure starts at 90 psi and after about a half hour of idle drops below 30 psi on the starboard engine the port engine settles up at 60 psi at idle what would cause the starboard engine oil pressure to slowly diminish like that. The difference between the port engine and the starboard engine after a half hour of idling is like 30 psi. I’d appreciate some direction where I should start looking thank you
Great video thanks very informative I want to ask I have cat c7 2005 my oil pressure when
Engine is hot is around 25-28 psi is that normal or it’s low oil pressure???
Hi there I got a question for you catc12 3406 it’s not started can you give me a hint what can I be
I learned a lot about this engine already in your videos. Thank You. But I still have a question, just please give me an opinion here. So I'm very close to buy a 1997 Tiffing Allegro Bus. It's a pusher and has a CAT 3127. I inspected and test drove on a super steep mountain. Everything works good. Temps are normal. Exhaust brakes work, has allison tranny. My only concern is the oil pressure gauge is barely staying in the green. As I accelerate is goes up just a bit. But it's not jumping. Blowby is minimum, oil clean, coolant clean, all systems read no fails in the computer. Question is could it be just the gauge or sender? Is that common issue, ... the chassis is freigthliner., is it a high risk of getting a worn out engine/bearings.? It only has 53k miles. Priced at 18k... coach is fair. Kindly tell me your opinion and what you have seen out there as I know you touch lots of rv s. Take care, and great job.
I mean 3126
Also, they didn't know if it's 275 or 300hp. How would I know?
Good info, but before you spend too much time or any money get an oil analysis done.
Sir any advance regarding check engine ln Detroit diesiel 12.7 thank you.
What causes high oil pressure
May i ask whats normal oil pressure supposed to be on a 2004 ford f150 short bed 4 dr truck?
Well done. A great presentation and kept simple which is important. Thanks for sharing your knowledge.
+0BMM1 You are welcome.
young guys ant banging down the gate to be mechanics. you may change that. thank god
Are you a. Expert in maxxforce engine have 2013 international giving be issued as to when I’m driving it just shut off. On the highway is fine but on the road it shut off unexpectedly? They claim low fuel pressure. It can be my ecm .. but when it shut off. I remove the cables from batteries then put it back it restarted again to drive.. help ? I my work horse. And putting me outta work..
MIKE GILLES too much electronics in a diesel for the working man,,the old diesels seem to run forever and they forgive you
I used to my car an oil filter (STP) it's easy to clog this filter for 2 moths only.That's pretty bad this product but know I learn a lesson .I never used again this oil filter is made in China.
Detroit 60 series oil pressure at idi is around 20 to 25 psi is that normal plz help ??
Hi am using c9 engine
now days I have low lub oil pr.low
I don't have fuel contamination
After changing filter and oil I have 3.2 bar
My other generators are 3.7 after filter and oil change
Now the problem is with in 250 running hrs the pressure drops gradually to 2.5 bar alarm level
Could u help me what could be the reason for this?
Hey man I have a Audi A4 2011 74,000 and the low oil pressure came on. I already changed the oil filter, changed the oil, the oil pressure switches. What else could it be? Help
My jake brakes malfunction when it's super hot. I was told it could be low oil pressure. How can I trouble shoot jake brakes
Did u find what the problem was? My truck's doing the same thing. Thanks
I have a c15 acert my oil pressure at 185 water temperature idling is at 30psi and running at 60psi when temperature goes 205 the pressure goes down to 58pis it cools down and goes back to 60 psi should I be worried about my oil pressure also whats the normal oil pressure on c15 Acer???
It's normal to go down a little when its hotter because the oil is thinner. 2 psi is nothing.
I have a C-12 engine idles at 2500 maxes out around 40 or 50. Is this normal

OK truck smokes on fire up?
normal idle smokes for 4 to 5 minutes. higher idle 900 only for two minutes. truck runs great all day long plenty of power. number 4 injector went bad changed, still smoking. done injector cut out number 4 smoke goes away. what do you think? 3406E 1LW
+Joshua5869 Kubo Sounds like you did some good troubleshooting so far and isolating it to cylinder 4. Alright well if you changed the injector and you still have smoke then it is something mechanical, now don't panic yet as it could be something non major. The overhead for number 4 cylinder needs inspected carefully, you could have a rocker arm or cam lobe failing. The Jake can also stick which would keep your exhaust valve slightly open at all times, which can result in that as well, if you suspect the Jake you can look to see if it is further out than the other Jake's or swap the Jake housings with another cylinders like 1-2 and 3-4, or back the adjuster off. Check your valve adjustment as well. Now if all of that looks good then that pretty much leaves the cylinder/piston/valves. So the head would have to come off. You can also pull the oil pan to inspect the cylinder walls, or do a leak down test with a rubber tipped air nozzle to see if that cylinder holds air properly. Hope that helps.
I have a problem the oil light on e46 318 take a time to go off what will be the problem
