PCV, breather, filler cap question.

Hello. I have a set of Moroso valve covers Ive been thinking of putting on my engine. However, they are bare.

There is a single hole, that looks like it is for a filler cap. Will a filler cap seal properley, or is there supposed to be a grommet in there?

Can I use another hole and put a breather on there to remove my PCV valve? Or, do I want to keep the PCV hooked up?

Also, should there be a baffle or something to prevent oil from splashing up into the breather?

Thanks alot.

? #1: They will probably need a grommet. Unless you find the right size breather.

? #2: It's up to you. But if you like a clean engine you need a PCV valve or a evacuation pump of some sort to keep the pressure down in the crank case. If you don't you will probably have at least seepage if not full blown leaks.

? #3: Yes. If you don't the engine will suck a lot of oil if your using a PCV valve.

My 2 cents. Hope it helps!
