3 OEM PCV Valves failed...What next?

[Sleezy_E]

Just like the title says, my boost leak has been caused by a leaking PCV valve. So I bought 3 more from the dealer and all of them leak during the boost leak test. I researched and saw that this is very common, even with OEM from the dealerships. Some people just replace the valve with a straight fitting, but I don't understand how that fixes the problem cause it has to ventilate the crankcase and seal up under boost. Any ideas?

The guys who replace it with a straight fitting also cap the fitting on the manifold so you don't wind up with a major boost leak into the crankcase.

Make sure you take the OEM parts back to the dealership and show then how they are failing.

Thanks for the info Steve, I'm going to order a catch can and do the straight fitting as soon as I can.
