The last time i drove my vette for a long period of time (about an hour straight) on the highway, when i got home i smelled burning oil. I smelled the exhaust and revved it and no smoke appeared so i popped the hood and was greeted by a steady cloud of oil steam from the passenger side of the engine bay near the firewall. further exploration yeilded oil stains on the headers where they bend back towards the back of the car. it isnt a significant leak, havent lost really any oil level. I know my oil pressure sensor is bad, but was else on the backside of the engine could drop small amounts of oil onto the clutch case/ exhaust?? if i snake my hand around the back of the motor from the passenger side, i can get far enough to get wetness on my fingertips from the back of the engine above the crankcase/clutch area. not quite the center of the motor or anything, but along the, what feels like, circular groove on the backside of the engine... ive never had it out so i dont know what the back of the motor looks like but i think something is dripping down the back of the block, into the circular groove and following the groove down, accumulating and dripping onto the hot exhaust. so... can anyone give me an idea of where the oil may be coming from? i ran my fingers around the valve covers and no wetness to be spoken of. can the seal on the oil pressure sensor go that bad that oil weeps through it? btw, i just switched to AMSOIL so id rather not lose any more of it. also, car doesnt leak oil onto the driveway at all.

 

Oil sensor would be the number one culprit in my opinion. Cam sensor is back there as well.

 

anyone else?
