Valve cover vent tube......

I have a Cobra intake, getting ready to install a tubular GT-40 until my Explorer upper is finished. I'm polishing it. If the air isn't that big of a deal, I can install a breather and be done, right?

If not, I'll install an oil fill cap, and move the vent tube to the back of the valve cover out of sight.

If I made this complicated, I sure didn't mean to. I simply want to know the best way to install plain, no holes, valve covers on an EFI engine that has A/C, and no smog equipment.

You make everything complicated. When is the day going to come where you stop swapping upper intakes? I thought your Explorer one was done long ago?

Well that is what i thought you did and i personally dont like it very much. A PCV valve is necessary on a street engine in my view. On a race only engine OK. But Vinny wants to clean up the engine bay not add things like that.

I think that is your 1320 car so it is totally cool other wise. Does it PUKE OIL???

I hear ya. I just don't want to over complicate things for Vinnie's sake. 8 pages explaining something as simple as a PCV system?

I am hearing that!!! And totally agree. But it is nice to see different things and ideas!!

The Cobra intake I have is nice, but the GT-40 is kind of necessary. It will run on the car for a while, AND, I'll be using it to gab a bunch more GT-40 intake plates again. hat brought in really good money to use towards the Sport.

The PCV valve on the back of the lower intake apparently stays where it is. I guess what I'll end up doing is install an oil fill cap on the valve cover, and moving the vent tube.These are taller valve covers as well, and I'm going to have to raise the intake a bit more, so, I will probably tap the hole where the tube is on the throttle body, and drill and tap a new hole on the back side of the throttle body to install the vent tube from the valve cover, which, I'll relocate to the driver side valve cover, under the upper intake.

It dose not puke oil works just fine ..... One day ill use a vacuume pump and pick up some hp

But with a breather on the vc and using the Pcv you will pull air ....just saying

And with a bigger intake I suggest running a oil separator if you don't want oil in the intake

I see what you're doing Vennie that sounds right to me

I'm almost betting that you could add an in-line filter to the tube as well to help prevent oil going up into throttlebody just in case in the future there's any blow by

I know it kind of sounds far-fetched but just a thought

This thread might relate to a question I have, about my v6. I have the tube going from the valve cover to underneath the intake. Theres an open end right above the valve cover connection, im guessing a breather, then half way along there's a 90° opening, connected to a solenoid, then to this black box, wich then goes all the way back to the fuel tank. I'm taking an educated guess and saying this is to somehow vacuum fuel fumes into the intake? my thought was to cap off all the open ends on this line and just leave the line sealed going from the valve cover to wherever it connects on the intake.
