Wouldn't it be better to have a valve cover breather rather than having a tube going from the valve cover back to the intake??? - Page 2 - Fuelly Forums

The part I'm talking about

The part I'm talking about is in this picture... I have a red line pointing to it.



As you can see the hose goes from the valve cover to the intake tube. The fumes and the oil gets sucked in the Throttle body. If you put a catch can in that area the only thing that will get sucked from the valve cover is the fumes, not the oil. The PVC is a completly different thing. It's in the back of the motor under the intake manifold. I'm not messing with the PVC, all I'm doing is preventing the oil from going back into the engine.

The PCV valve sucks air into the crankcase. The air that is sucked in usually comes from a hose from the valve cover, which is connected to either a dedicated filter, or betweeen the air filter and the throttle body.

If you just disconnect the duct in your picture, the PCV valve will suck unfiltered air into the crankcase, which is not good for the oil or the engine. The way to prevent this is to simultaneously disconnect the PCV valve. This is why I discussed the PCV valve earlier. Sorry for the misunderstanding.

I think we all need to switch to caffeine-free cola.

As you can see I went to home depot and bought the stuff for the vlave cover catch can. It will fit my hoses perfectly. The only problem is they only had enough stuff for one side. So I need to buy for the second side later on and just attach to the car. I spent $30, and the other side will be $18. SO basically $50 for a good catch can. I'm now thinking it would of been better to just pick up the greedy catch can that is $70 and made for the car.

hoses and PCV

Hey the hose to the air cleaner is both a fresh air supply and excess pressure vent. The PCV draws air through the crankcase while there is vacuum to remove and gasoline fumes in the crank and blowby and it takes air in from the hose going to the air cleaner to provide clean air into the crankcase. In the even that there is full throttle applied and no vacuum and or a lot of blowby past the rings then the crankcase fumes may not be able to flow through the PCV and they then vent into the intake of the carb/intake manifold air cleaner to be sucked into the engine otherwise you blow the oil pan or engine seals out. Combustion pressure is a lot higher than the compression pressure.

It looks to me like you

It looks to me like you bought the wrong brass fittings for the filter. You should be able to get standard hose fittings designed for air tools for about $1-2 each. The whole catch can shouldn't cost more than $15-20.

The more I've been thinking about it you really need to put this on your PCV valve, and not your crankcase. The crankcase is where air comes IN, and the PCV valve is where it goes back out into the intake manifold. All that you'll be doing by putting the filter on the crankcase hose is filtering the air that goes into the crankcase.

If you really want to filter the air out of the intake manifold, you'll put this in line with the pcv line.

Oh, and return the brass fitting and get the cheap ones. There is no need to spend $18 on a brass fitting.

You guys are confusing me.

You guys are confusing me. Where am I suppose to put this thing???

Here is a pic of my PVC valve. It's top right corner. Just point in the picture where I'm suppose to put the filter in.
