REAR END LEAKING???

[1stTurbo]

Its looks like the rear end is leaking through a plastic cap in the rear housing. Do they make replacement caps for that? It looks like it is a filler hole that has a plastic plug that goes into it.

It is the fill cap, should be plyable rubber like. don't know about a replacement. you may just need to take it out and clean up the cap and cover.
