Hello forum family...been a while since I posted. Haven't researched any posts on here yet because of time concerning my experience...but here goes!

Had to accelerate hard to get around a few slow cars last night. The V-8 moved as expected with little effort. After coming off the accelerator I experienced exhaust smell coming into the cabin. I had the driver-side window down about 2 inches. Smell lingered for little over a minute then dissolved. Could this be gasket leak around manifold area??...no check engine light or funny noises from engine or codes.

 

No reply needed...found problem. Valve cover gaskets

 

Swap in spark plug well gaskets while in there.
