I couldnt wait and didnt want to go spend more money since im on a budget here, but I bought these valve covers from autozone, there like the ones tehy have everywhere. One side has a oil fil cap, the other has a breather head, the other side with teh oil fill side has a breather head too but with a hose coming off of it. Is that a pcv valve or do I have to add my old one to it? Sooooo confused.

A picture is certainly a good thing in this instance.......:confused:

What he said.. bring on the valve cover porn!:crazy:

Yeah cant find my camera though, my lil bro has been stealing things lately. Long story, ill post in SP section later. I found out it is a pcv valve though...freakin huge to be one though, jebus.

The holes in the covers are the same size for a breather as they are for a PCV valve. It's the size of the hole in the rubber grommet that goes into the valve cover that is different between a breather and a PCV valve. Generally, the breather grommet hole (about 1") is bigger than the PCV grommet hole (about 3/4"). The hole in most aftermarket valve covers itself is right around an inch and a quarter (I think it's 1.22" if memory serves) .

you can buy the grommets from any aftermarket company like Mr Gasket. they usually come in pairs...one has a bigger inner hole than the other...one for your pvc valve and the other for a cap or breather.

Thanks guys, it was just a wierd looking pcv valve, odd?

LMAO

Im just full of info tonight. One tip I got from an engine guru is look at bottom of PVC valve n make sure you get the right number. They are rated for different pressures.

"PC valves are rated. They are all vacuum actuated, and have different ratings for every engine package.

Example, 1966 Corvette 427.

390 horse, 10.25:1 c/r, hydraulic cam, oval port heads, Q-Jet, uses a valve marked 2.

425 horse, 11.00:1 c/r, solid lifter cam, rectangle port heads, Holley, uses a valve marked 6.

the difference, the vacuum level the engine runs at. 390 has more overall vacuum than the 425, so...the valve has to be different for both, so they operate correctly.

Take a look at the valve plunger inside the old valve and see if there is a mark, number/letter, or both, on the butt end of the plunger.

If you know the level of vacuum the engine will run at,m you can select a valve that will work the best, and have the right hose outlet angle. Like the Chevy number 2 valve has a straight hose barb, but, a Ford whatever has the same number, and a 90 degree hose barb, etc. Mix and match is the new order of the day."
