I have a 94 3.4 5 spd firebird. Has 133k, cold air, stock otherwise.
My problem is that when i first start driving in the morning im reading 40 to 60psi oil pressure, after about ten mins when the engines warm it drops down to about 5 at idle and 20 to 30 when driving. Im pretty sure thats not normal, what is?
There is no knock or any noise whatsoever coming from the engine other than a small exhaust leak somewhere. I have a feeling its not the sensor because i feel a difference in acceleration and engine vibration. First thing in morning it runs smooth. Warms up and its rough vibration and slower accel. My oil is full, regular oil changes.
I do smell oil burning when i get park and get out, its coming from the engine just dont know where, its not bad enough to drip to the cement, i let it sit 2 days and not one drop.
Any advice i would greatly appreciate, anything i can do til then a thicker oil like 10w40? Lucas?
thanks
