Okay I had a thread about my low oil pressure, but I'll make one more before I completely give up on it... I was driving the car a few days ago and sitting at a stop at Idle I look down and I see the car running with about 10lbs of oil pressure. So I drive it 30 mins back home. While sitting in driveway oil pressure fluctuates from 20-10-5 all the way down to zero at times. I was almost sure opsu must be bad so I changed it out, but still have same problem. So than I put a mechanical gauge on it and still the same thing.. After this I go to gm and buy a oil pump and go ahead and put it in. I get the engine back together and STILL low pressure. Is there anything else I can try with the engine in the car? And if not what should I check for when I pull the engine? Or when I pull it should I take it to machine shop and have them look at it? I'm assuming I have to have either a spun bearing or a blocked oil gallery in the block.... Btw the engine has never been abused, never run on low oil, and change oil every 3k miles with mobile 1 synthetic...

Only 50k miles... No knocking, but I've been told spun bearing doesn't mean it will knock. Professional engine builder told me 97-00 ls1's had bad oiling issues and they don't even take them as cores because of the bad oiling issues... So I went ahead and bought a forged shortblock from Thompson motorsports for $2400!

If you had red towel on yours you must have dropped a rag in there or something? I have never left anything in mine. Only been apart once many miles ago. I'll be out of town for atleast a month though so who knows when I'll get a chance to pull this bitch and get my new motor in...
