Boost leak - pcv system?

[thspoq]

I've been fighting a random misfire and lean idle condition. I decided to pressure test and the only leak was coming from the pcv (pancake) valve. Is this normal? If not, what should I consider inspecting/replacing?

Thanks!

It shouldnt if you have the oil cap off, but sometimes you can feel a little coming out.
If it is a lot, prob the check valve.

How did you test the PCV system? I thought it had to be capped off at the y-pipe when doing a boost leak test?

You remove the pancake valve from the Y-pipe and cap off the Y-pipe connection.
