Stupid question about valve covers
Stupid question about valve covers
Okay, so a friend was talking about getting some fabricated aluminum valve covers because they look neat. Fair enough, but I am wondering: what do you do about the breather
(or PCV) and the oil fill, as the covers have no holes for them? I think I'm missing something.

I doubt there's an oil fill on them. That's the least important hole in a valve cover, because you can just pop out a breather to fill your oil.
My CHEVROLET cast covers came with absolutely no holes of any kind. I drilled a breather hole in the passenger side cover and a PCV hole in the driver side cover. When I need to put oil in it I'll pop the breather out.

Very. If you don't have a PCV valve in one and a breather or some other type of air supply (i.e. the stock configuration that pulls from the aircleaner/throttle body area), you'll build up crankcase pressure and squirt oil out of every gasket on the motor.
Ask me how I know this.

I have those fabricated valve covers. The breather on the driverside has a built in PVC valve. Its held in by a c-clip, so its replaceable. To put oil in, just pop out one of the 2 breathers, and presto, hole for filling. I can't get a picture to load. They are all to big.
