got a auto specialist breather on the cossie , same type as the bailey ones , breathing from both sides of the block , smallest port on the breather returns to the factory 4x4 sump port thing and the big one vents to atmosphere , now am getting smoke out of the one that vents to atmos .
car is running t34 and 55lbs with a 32psi peak , also heard that the t34 does create a lot of turbo back pressure , could this be the cause or is it rebuild time ???
cheers
