I ordered part #4246 Elite series covers from Summit last night, then woke up this morning and walked out into the garage to have a look at the car. I know I ordered the correct ones that have the oil fill on the left side, but does anyone know if these have PCV provisions, or do I have to drill for my PCV valve? Summit's tech guy didn't know, and Edelbrock isn't open for a few more hours...

Any help is sincerely appreciated. If drilling has to be done, does anyone know what size it is?

 

I'm pretty sure you'll have to drill.

I don't know the size, right offhand. However, the best plan is probably to go to the parts store and buy a grommet (they have them hanging on cards along with the PCV valves), and measure it, and drill holes that size. Don't take anybody's word here for what size they are.

Don't forget, you'll have to fab up some sort of baffle for it too, on the inside. Typical stoooopid aftermarket valve cover deal. And of course, the same deal on the opposite valve cover, where the fresh air intake (the other half of the PCV system) has to go.

You'll hate those things soon; they look super retarded when those little genuine faux plastic Allen screw heads start to fall off.

 

You know what? If that's the case, I might just go through GM parts and buy new OEM valve covers for it...I think I can get them still. Mine are just pretty rusted and pitted, and I'm trying to clean up the engine bay. This car is staying relatively stock, and I drive it about 5-6k miles a year. One thing I've learned is some things are better left alone

The Elite air cleaner was worth it for the open element, but maybe this is an annoyance I should avoid...like I said, I just wanted to pretty up the engine bay a little. I wasn't entirely sold on the valve covers anyway, and I already put a hold on the order with Summit.

If anyone else has anything to add, that would be great...but I think I'm better off just doing OEM covers, assuming I can get them (I think I can...)

 

i have elite valve covers, all i did was i used there grommet, bought a stock fram PCV for an 86 z28(il get you a part number), it fit in there, so i used it, installed the baffle in the one valve cover and not the other, everything seemed to work fine, no drilling required

i dont know if your will be any different, but does only one of your VC have a hole in it?
