IE Billet Valve Cover install DIY/Instructions?

**Danaldson** · 05-27-2016 07:26 PM

I believe my replacement OEM valve cover has also broken, and i found an IE valve cover for a great deal.

does anyone know if there is a way to install this without running a catch can? I plan on ordering an IE can soon but was wondering if i would be okay to run the cover without one for a while.

I also picked up the Rear breather block off plate, Intake manifold cap and Evap Relocation tube.

Does this look okay to run? something tells me this is wrong and it will build crankcase pressure?

Any help is appreciated thanks.

That is wrong. The port on the VC and the primary oil separator need to be connected with a T fitting and then routed to a catch can or back to the intake (via intake breather port shown). The way you have it drawn will not allow crankcase pressure to escape because you are just routing it back to the crankcase.

Oh, and the n80 gets routed around the VC and to the small hose that used to connect to the oem vc. It basically just goes back to the intake.

Right the evap just used to go through the vc now it's around.

Okay that's kinda what I thought.

So I connect the valve cover port to the primary oil separator. And then in the middle have a t-fitting either going to a catch can/vent to atmosphere, or run the line to the intake manifold?

Yep, the VC port and primary oil separator are the "pressure sources" and you need to give them a path to atmosphere or to the intake.

Cool. I think I sorta understand it now.

Just to confirm... This will work?

@Danaldsan Correct. Preferably i would route it not the intake manifold or atmosphere but to the TIP so the crankcase is always under some vacuum even under boost. I would just modify the rear breather that connects to the turbo with a barbed an fitting and secure with some hose clamps after the catch can

So for now, routing the t fitting between the vc and the oil separator to atmosphere is okay? Just run a line to the ground? With blocking off the factory breather location?

And then once I get a catch can. Pick up one of these.

If youre on the cheap you can just reuse your old rear breather port instead of that an adapter. But for now venting to atmos is ok as long as you dont regularly race/track your car.

also what fitting will i need to connect the primary oil separator line to the New an fitting/line

Still having issues with the consumption?

Yeah. Still smoking quite a bit.

So installing this valve cover and putting on the rear pcv block off plate, theoretically i should be able to tell if my consumption is pcv related or not.

If the smoking stops out the exhaust, but oil consumption still happens (oil would be pushed out the atmospheric tube to ground) then I know it's pcv related.

If the smoking continues out the exhaust. The next steps would to check the turbo, and then potentially rings/Pistons

Could you not simply do a compression test to see if it is the rings etc?

Any chance we can get a diagram of how it should look with a catch can? Final result? Either a drawing or images or both

I was looking to see how the coolant hard line reroute kit looked as well and I just came across this randomly, score! I can't wait till I get out of California and I can do some fun creative stuff.

Would work just fine as you have a check valve preventing manifold pressure from entering the valvecover.

**blakefife** · 02-24-2022 03:43 PM

thank you. i was essentially wondering how to run that Aluminum valve cover without a catch can and have it recycle through the intake system sort of how the stock system does it now, but with one less oil/air separator (the pcv valve unit is gone).

I will actually try a new plastic valve cover and updated breather tube (06D103215A) with the check valve. if i still have problems with the valve cover, ill remove it and opt for the aluminum one and run my 10AN hose to my new updated breather tube.

Ya can't run an aluminum VC and stock PCV setup, need a CC with it. And when ya run the CC, ya need to send it to the TIP. Otherwise it won't vent at all under boost conditions.
