99 chevy tahoe LT 4x4 low oil pressure reading only after its warmed up sitting at an idle and the same when I am in drive on the brake. Check gauges light comes on when it drops down to approximately 5-8 on the tack. As soon as I get on the gas the light goes off and the tack reads up to 13-16. No engine noise as of yet and only had to add one quart in 2 months. No leaks found. Has me wondering if the filtering screen for the oil pump might be clogged? I dont want to tear into it for nothing if thats not the problem. Any suggestions what could be causing this?
