Oil shoots out of filler cap when open. Is that Normal?

[Ill-EagleTSi]

The oil filler hole never leaks or any of that. But if I take the oil cap off while the car is running it splatters out oil on the valve cover.

When I bought this car the pcv valve thing on the valve cover was disconnected and just has a little filter on both the intake and pcv tubes that come off the valve cover. Is that why my oil filler hole splatters oil if the cap is off and engine is running?

Also when I take the cap off I hear a kind of like bass sound really quiet coming from the oil hole. Almost like air is coming out

That's perfectly normal if the car is running dude, think about it. Peek into that filler hole while the car is running. You'll notice your intake camshaft if flinging oil everywhere because it is spinning.

Are you sure you mean pcv valve or are you talking about the breather? The pcv valve is on the back side of the valve cover and the breather is on the left side (looking at engine from in front of the car).

Are you still running a stock MAS? If yes you'll want to cap off the hole on the intake tube where the little filter is, otherwise you're pulling in unmetered air and risk running lean.

This should keep you busy for a while

Thanks...yes both of them, the breather and the PCV have a little filter on them. Is it okay to run like that? Or do I need a catch can?

Thanks for the link. I just rebuilt the whole engine so It has all new parts on it!

I'd say you don't need to have a filter on the PCV unless you have excessive blowby. But since you do, make sure the vacuum port on the intake manifold is properly capped so it doesn't pop off under boost. I run a catch can on mine as the little filter would eventually get soaked with oil and lightly spatter everything around it. I made my own for like 10 bucks from home depot, works great.

As far as oil spit with the oil hole open when idle Its normal. The PCV is at the top of the valve cover facing the intake manifold its gold and it is conneted to the intake manifold. If you are talking about the "little tube"at the right side of the cover that goes to the stock mas of the car it could spit a little oil(if disconnected) and it is normal. Mine dont leak any oil

You should close the hole that remain at the mas intake. Correct me if rong
