Thread: car only getting 15mpg. and a screeching noise from rear main/flywheel area

Fix the pcv in the charger.

There is an o-ring on the pcv, then a spring above it and a gasket on the cover.

My pcv didn't have an o ring. There is a piece of plastic that the pcv sits on and and then the spring. And gasket and cover. I have eliminated the transmission by taking the torque converter bolts loose

That is the problem, you need an O-ring. It seals the pcv so you don't leak full manifold vacuum to the crankcase all the time.
