I did some reading last night and ended up buying an oil catch can system. After seeing some stories and pics on here, it got me a little worried. Anyone in here put one on?

Okay, what about if it goes into 70 nearly 80?

That's what mine does... About 40 during cruise and 75-80 at WOT. Oil pressure is computer controlled. Above 3500 RPM it goes into high pressure mode.

 

And no, contrary to popular belief, high oil pressure does NOT cause oil leaks - at least not external ones.

Hey Everyone. I recently purchase a 2014 Chevrolet Silverado Double Cab 5.3 V8 4wd. One owner, almost 30k miles on it. When im cruising my Oil Pressure is around 40 PSI. when i stop or press the breaks my oil pressure drops to around (25-35) PSI. When i turn my truck on the mornings. its around 40 PSI but then it drops to (25-35). is this normal. i check the oil and it seems fine. i dont hear any noises on the motor. Any help would be appreciated or feedback.

I have a question...So I have the AirRaid JR kit on my 2014 Sierra 5.3 I removed the mass air flow sensor and the intake cover just to routinely inspect the filter, after I reinstalled the filter box cover and the mass air flow sensor I started the truck. The truck had been sitting for about 3 weeks without being started once it fired up the oil pressure gauge went up to 60psi and stayed there also the electric cooling fan kicked on. After 10 min of idling the oil pressure gauge stayed at 60psi and the electric fan was still humming away. This has never happened before and is very abnormal it usually fires up and hangs around 40 psi. I even drove it around the parking lot to see if it would drop down and it never did. Just stayed at psi and electric cooling fan was just humming away like it was hot or something. I stopped the truck turned it off and back on again and it all went back to normal psi and no electric fan noise. Anyone ever experience this?

I have a 2014 tahoe, that I the oil pressure low light came on while sitting idle. Had the oil changed and took it to the dealership. Dealer thinks changing oil may have fixed it. I never noticed oil pressure until now. Starting up in the morning I am at 40 psi. After driving and then being idle it has been staying just above 20. When driving highway, I am 40.or just below. Is this normal or should I worry.

What mileage is on your tahoe? Was the engine run LOW of oil? 20psi is lower than it should be at idle, but this could just be a sensor issue. Maybe the dealer could do a pressure test to verify actual oil pressure and then they can determine if it is just a gauge problem or if your engine has a real problem. You should still be under warranty I would push the issue with them, something is not right.

a good rule of thumb (very generic and not brand specific) is at least 10psi per 1k rmps.

Wait...  Rule of thumb?  ?

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
