Custom Rocker Covers V6

They look good Steve
A word of caution though: make sure there is no blasting medium residue left on the inside of those covers, especially lodged behind the baffle plates. Someone on here found a lot of grit in his engine, possibly as a result of this, prior to his ownership. Just sayin'.

Cheers glen, just checked the insides of them now, there squeeky clean

As far as I remember, they should also only be freshly powder coated on the outside. Leave the inside as it was. Just clean it.
Didn't I read this somewhere on here a while ago ?

Sorry to revive an old thread.

I'm ordering these nice cast valve covers for my S3CS and my question is there a need to have ventilation on both covers or is it enough with one.

I will not use a PCV and run an aftermarket ECU.

Thanks

In theory I'd say no, both sides are connected, but might be better to have one on each bank?

Can't have too much breathing or try it and see if you get oil blowing out the dipstick tube

If you're using PCV you would want an inlet on one side and an outlet on the other. That gives you scavenging flow across the engine. Since you aren't, it doesn't matter which side the outlet(s) are as long as the total capacity is big enough.
