certified22
Gotta give it to the boys at GM my 04 Z-71Tahoe 5.3L is running strong still I had the low oil pressure issue 10psi @idle 10-15psi @ 1000-1500 rpm 15-20psi @1500-2000 rpm sometimes I might get up to 24 psi but never more usually maxed out at 20psi I ignored it for a little bit till due to wife spending money she was not supposed to that's another issue but the first time it sounded the low oil pressure alarm sitting at a red light I parked it got my parts drove it to my shop started pulling the front differential got it out the way drained the oil when I pulled the plug there was more metal shavings on the plug then I cared to ever see pulled the pan the pick up tube screen covered in big metal shavings went to clean the pan I have never seen that much or that big of metal shavings in any motor still running cleaned everything up in solvent tank put new o ring on pick up tube put it all back together and I have an increase in oil pressure but not much get 30psi on the highway it doesn't drop below 10psi at idle or red lights anymore the low oil pressure alarm sounds at 6 psi I think and it not doing that and running fine but it was running strong before as well I've never had a loss of power my check engine light has stayed off and it comes on randomly due to intake gasket replacement needs but turns off when it warms up I only run royal purple oil and and Lucas oil stabilizer in it 5 RP 1 LOS and an AC Delco oil filter every oil change I only run premium gas in it I care for this truck like I care for my children so now I have to decide motor rebuild or motor swap I was gonna pull the rod caps but I was so fed up with the **** bullshit of the whole situation (and that's not a racist comment) and I'm sure it's the main barrings so I didn't well that's where I'm at any input is very much welcomed although I doubt anyone will comment for sure no GM technicians will even though the forum is called Ask a GM technician cause I've been posting all kinds of questions about this project before I started and I've gotten nothing but crickets chirping on those questions so comments are welcome as a reminder to those who have this same issue I'm not ASE certified but I am certified to take anything apart and put it back together in better working shape than it was been wrenching on cars since I was 5years old been around the world 3 times met a man with a wooden cock drove every kind of truck there is 2wheel 4 wheel 6wheel 8wheel even those big mother truckers that go pssh pssh when you step on the brakes I'm a huntin fishin hot lady ****in rootn tootn shootin double cap crimpin motor building red neck from iKS that's going back for more every time and if you made it this far DO NOT!!!!!
