EuroJet PCV Fix

EJ PCV Fix

This is the Eurojet PCV solution.  It is essentially two pieces of silicon with a machined aluminum check valve.  The check valve ensures that boost does not leak out of the intake manifold and into the crank case.  It also supplements the stock check valve.  It does what it needs to without any frills.  However, the flow of the check valve is not really known.  The stock pcv valve goes from open to closed with hardly any pressure.  Eurojet’s valve is stiffer.  I’m not saying that this is necessarily a problem but it is different from the oem valve’s operation.  For those who want a pcv fix that allows the pcv to function as intended (route crankcase vapors to the intake under vacuum) this is the fix.  Volkswagen has released newer, updated revisions of the oem pcv valve but failures can still occur under higher than stock boost levels.

I still feel that the newer catch can solutions are still your best bet for fixing boost leaks involving the pcv system.  It’s a little more maintenance (having to empty the can out) but it helps keep the intake tract a little cleaner.
