I have a 2007 tahoe ltz 5. Had the same problem works fine till the oil heats up. So what about when the engine is idling? Oil pressure around 40 driving, and 30+ at idle. I'm having what sounds like the same issue as everyone else, except this is the 4th time. I had an 04 GMC 1500 with 5. There was no harm using this chemical. Reassemble without that stupid Luck. Maybe there really was a pressure problem? I never was able to catch the pressure change when the code was thrown, but I did capture this data in the picture for one of the P0521 codes. Oh by the way I bought new in 2003 have only 137K and used synthetics only every 5K. I installed a new oil pump, but the old one looked fine and was not the issue. I have since Changed the filter and added Lucas oil stabilizer and changed the oil pressure sensor/switch. The sensor requires a special socket to remove it because of the way it is made in some case socket is also available at the auto parts.
Oil Pressure Low At Idle
Mechanic replaced the screen and oil sending unit today! In and older model with 200K, I think I would start with the oil pump and O ring first to see if it fixes your problem. All of those problems were due to limp mode, not throttle body stuff. 3L just started this crap. I may have bought bigger problems down the road with all of the gadgetry! I had this problem on my 2008 Silverado at about 105, 000 miles and this thread really got me going in the right direction. I got the low oil pressure signal while at highway speed, stopped, checked oil(Full), no engine clanking so I carefully limped it home, stopping several times when the pressure returned to zero. The check engine light was on when i test drove it oil pressure seemed ok though well they told me they ran the codes and it was a evap code and there repair shop would fix it no problem so i bought this thing and being a ex ase tech i decided to run the code my self when i got home it was just bothering me... As many times as the motor lost pressure and wasnt making any noise i was sure it was either the gauge or pressure sensor. This is what happened to me and how it was resolved. I also plan on purchasing the larger oil filter and if all that raises the oil pressure I will go back to 5W-30 oil. I have a 08 Chevy Avalanche.

Sometimes when it starts to act up it turns a blinker on all by itself. I've already changed the sensor switch and I still have the same reading on the dash. What was the problem. That is where I would start next. Our son took his to the dealer and they charged him over $500 I was fishing with a retired gym mechanic and he told me he could change the gauge in 15 minutes. FIX, put in few ozs Seafoam, drove bout 75 miles, I changed oil and new Bosch oil filter! On the other hand, oil pressure above 80 PSI is too high. After doing all of this we still had the problem of the oil pressure dropping. Took to local guy, he suspected the screen right away. Start at the auto parts and buying a new manifold gasket set. Do not take it out and not replace it.

Thanks to all, for helpful info. Truck still runs fantastic and does not burn any more oil than it did since new. New oil pump, new O ring on the pick up tube, fresh bearings, rings, lifters, NEVER EVER used a Fram filter in my life. This really limits my choices for oil changes while on the road. Its hard to get at, but it can be done easily with a proper set of tools including a oil pressure socket) Ran fine for about a week, then the low oil pressure returned and worse than ever. Also, I was using Valvolene Max-Life 5W-30 synthetic blend oil. Engine had problems at 230K with lifter noise before I got the car. Should I expect another issue or not? There are several reasons for low oil pressure: a bad pressure sensor, a failing oil pump, blockage within the oil filter; luckily these issues can be addressed before major or irreparable damage is done to the engine. I am basically having the exact same symptoms and same year truck.

I driven daily and on 1000 mile trips pulling a 16' cargo trailer- no issues, just lower PSI than my suburban with same engine. Underneath the intake manifold is the Oil Lifter assembly. I have 158k miles on my truck. Become a Member Today! I have an engine with DOD/AFM. GM should put this on their 100k mile maintenance schedule.
I personally filed away some of the plastic casting from the intake manifold, on the driver side to make more room... otherwise, expect a bloody knuckle (the one below your thumb).
