Hey guys, I own a 1999 Civic that after revving at high RPM and coming to a stand still I notice a smell coming from the car. It has a couple leaks that I have already fixed, distributor and valve cover, but I have not gotten around to fixing the oil pan gasket leak. Could this be causing the smell emitting from my vehicle after burning off. The smell does not come from the engine bay nor the tail pipe. Also just to add in, Ive noticed a bit of blow does this mean that my piston rings are worn out or could it be that my PCV Valve needs to be replaced.
