think i figured it out.

MIGHTYJO3YOUNG · April 26th, 2008, 09:20 PM

A week ago or so I posted about a loss in hp....well i went to put on my fuel pressure regulator today and also was planning on fixing a valve cover leak. Turns out there was no valve cover leak. It was coming from my intake manifold. When i replaced my intakes the old one had a tube going to it from the middle of the back of the engine with like an oil filter or somthing. I guess its not sopposed to go to my new intake? It was leaking from a loose plug under the intake which also was causing an unfindable vacuum leak until now

. Anyways, should i just plug that hole up in back of the engine? Also my fuel reg was a universal...so it doesnt bolt right up to the old parts. do they sell adapter pieces or somthing? They just gave me two tubes with the reg so im at a loss right now. Thanks fellas!

MIGHTYJO3YOUNG · April 26th, 2008, 09:54 PM

why was it spewing oil into my intake? i know it went to the bottom of my intake on the stock...but on my new its just putting oil into my intakes. Also whats it for?

The valve itself is either missing or stuck open. Its there to vent crankcase pressure.

MIGHTYJO3YOUNG · April 26th, 2008, 10:03 PM

should it have oil coming from it?

fogged306 · April 26th, 2008, 10:20 PM

no, oil shouldn't be coming out of it.

MIGHTYJO3YOUNG · April 26th, 2008, 10:43 PM

uh ohhhhhh

fogged306 · April 26th, 2008, 10:45 PM

check the valve... take it out and shake it, if you don't hear anything, its bad. Its a very cheap part that you can get at any parts store.

oil coming out of the bottom of the intake? That is normal, make sure the metal screen is in there.

MIGHTYJO3YOUNG · April 27th, 2008, 02:06 PM

it shouldnt be able to leak into the actual valves of the intake though right? Anyways i rigged it to get the fuel reg on for a test run, im gonna have to figure somthing els out though cause its not gonna last. SHE BREATHES!!!! It idled sounded and ran soooo much better! Probably from the vacuum leaks i found and i dont really know about the reg. I tried to adjust it, but nothing really happened whether i moved the nut up or down.. the pressure gauge read at like 70 psi and i know that cant be right... Either way the car runs like a beast now

fogged306 · April 27th, 2008, 02:08 PM

No it shouldn't be sucking oil up into your intake, did you take out the valve and shake it yet?

MIGHTYJO3YOUNG · April 27th, 2008, 03:07 PM

I took it out, shook it some, the ball inside seems to be fine. there is a screen below in the hole where it goes. What would cause oil to come up through that?

ryans88gt · April 27th, 2008, 03:14 PM

It happens, not a big deal. The PCV valve will not stop oil from getting sucked up. You can put an Air Oil separator for an air compressor on the line (like $40 one from Lowes or Home Depot) if you want to keep all that oil vapor out of the intake.
