well i wouldnt say the leak is bad, but bad enough for my liking, its only on the passenger side rocker, driver side is free of any leaks.. i get white smoke from start up but i assume thats condensation. my afb engine in my b5 v6 tdi has a breather mod, im running 260bhp and still get oil to leak from the passenger side rocker, i think to be honest its just a matter of the seals gone and need a new rocker cover.
