extra valve cover hole

[RustyBuckets]

I have aftermarket valve covers for my carbed vortec engine.
The old covers had one hole for pcv and one for the oil cap/breather.
The new valve covers have one extra hole, same size as breather.
What shall I do with it.
thanks Ya'll

So far that is the best response to the guys question, "**** it".

Yeah, just get a vented to atmosphere breather cap.

A couple of things I've learned:

The vented cap is best located diagonally opposite the PCV vent. So generally it will go in the rear RH corner. Fresh air is drawn in through the breather to replace what is pulled into the carb through the PCV valve/line. Placing it there creates a nice front-to-back and side-to-side flow of air across the inside of the engine that most effectively allows the PCV system to sweep the fumes from the crankcase.

On oil fill cap location:

Whichever opening you choose for the oil fill cap - make sure that there are no baffles under it. If you do find a baffle plate - either cut the whole thing out or bend the fins so that they are vertical. If you leave them in place and horizontal, it takes for-frickin'-ever to add your motor oil to your crankcase.

Excellent tips as always, Chengny! Never thought about breather location in that regard.
