I recently installed a 9 lb. powerdyne on a tired engine. I am leaking oil out of the dipstick tube under boost. I need ideas on how to fix this short of a rebuild. I put a breather at the oil fill. Is there a check valve, or something I can put in the vacuum line to prevent boost from entering the crankcase at the pcv? The other vacuum lines are capped, short of fpr and vacuum tree. Any help would be appreciated. Thanks
: I may be wrong on how the extra pressure gets in the crankcase....but that's what's causing the problem.
