Crank case vaccum helps the piston rings seat.auditurboquattro said:Ask Javad about this one. He diagnosed this issue for me a year or two ago.
My 80tq will smoke (a lot) out the tailpipe on decelleration if the crankcase breather is not hooked to a vacuum.
My guess is the pressure differential in the valve cover helps the valve seals do their job?
