[QUOTE="TTUhouston, post: 15653908, member: 185096"] Interesting issue. I also had some issues with my PCV system recently and am moving towards a breather system (right now open to atmosphere; breather on the way soon) due to boost leak issues with my Paxton. It was leaking through the check valves back into my valve covers on the PCV breather crap. Reading through the post it sounds like you already have breathers which means if you do have high pressure on your crankcase then the source of that pressure would have to be from the combustion chamber through blow-by on the rings. If you did install a dP you would put one end on the crank case and the other end on the feed line to the turbo? IF your issue is excessive crank case pressure due to blow-by this value would be near 0 (say 2 in Hg in crankcase, 2 in Hg at feed) which would also imply near 0 flow. If the dP actually read a reasonable dP (in inches of Hg I assume?) then that would imply that you DO have flow. Actually reading a high dP means you have more flow vs less but knowing what a high vs. a low dP actually is in that system would be the challenge. let us know how it comes out!! Some interested engineers willing to lend a hand but without measuring flow (which is expensive) I am not sure if we know yet how to diagnose this issue with the available sensors/etc. Do you have IAT2s? Any other additional diagnostics installed for the setup? [/QUOTE]
