So he'll probably just make sure it's safe and make whatever minor tweaks are necessary until then. Thank god my shop/tuner are nearby lol.

Update? I'm having the same issue with my PCV line leaking I think.

i was leaking badly, i fixed it initially with a check valve (linked above) which worked great, but i've since gone to just capping the intake manifold and venting the pcv line along with the crankcase breather. don't want none of that crap going back into my engine. a catch can only removes oil, not heat ;).

you should definitely be running a check valve between the manifold and pcv or manifold and catch can if you have one. if not, you're probably leaking boost and pressurizing the crankcase.

Also double check your evap solenoid vacuum hose at the manifold. I have found a leak there as well as no clamp is used on it.

do you put a filter on the vented lines ?

Is this a part the local napa/pep boys/autozone would carry?

yes i did. on the crankcase breather (the pcv is one way... only flows out, no need for a filter).

no, you want one of these. it's very important that you get a valve with the correct opening vacuum.

Awesome. Just placed 2 orders (1 to my house, and one to Pure Auto in case it can get there in time for tomorrow's install.)

Thanks again.

Below the manifold towards the driver. You will see a blue connector, its hard to see, the solenoid is literally below the intake manifold. If you haven't gone to crazy PS numbers, (like 14+) most probably its ok. But you would also notice some kind of symptom of vacuum leak.

Well I think James won't be able to post but his picture showing the check valve installation isn't visible. Can anyone post it or similar? Thanks.
