Thats exactlly what I did at work the other day was look up Earls fittings. The can takes 1/4" NPT fittings and the vac line is 3/8. I looked at a 90 degree 984206ERL and a 45 degree 984406ERL. It will work perfect. And there is a petcock on the bottom.

The catch can retains any oil that is sucked through the PCV hoses from the valve cover. Without the can the inside of your intake manifold/runners and cylinders will get horrid nasty. Sometimes a buildup gets so bad it can start to cause a ping problem. The carbon on top of the pistons stays so hot that IT ignites the fuel rather than the spark plug.

 

I bought one of those about a month and a half ago and its still sitting in the box cause I have been dealing with motor **** non-stop. Ill sell it to you for 15bucks on there its going to cost you 25 shipped. Let me know if you want it I think its the chrome one.


Silver I may try that since you ahve made it so easy with the pns for the earl fittings and everything but Ill ahve to wait gotta pay some other things off first before I spend anymore money

 

What exactly does a catch can do? Im new to this. Are they really worth the money?

 

I've not seen one installed and can't visualize how they hook up. Can someone post pics of where the hoses run and maybe how they have the can positioned? Thanks. Jim

 

It goes in series in your PCV line between the PCV valve and the intake/TB. It collects the oil that is normally pulled into the PCV system and into the intake.

 

How about this one from Jaz? Sells for around 45-55 bucks.

 

What are they used for? Are they for air suspension?

Catch cans are pirmarily used in ultra high compression/power engines and forced induction when there is a ton of cylinder pressure. Sometimes the cylinder pressure pushes past the rings. This causes the crankcase to pressurize and "push" oil out, usually thru the PCV or crankcase vent on or near the valve covers. The cans gather the oil like shown in the clear picture instead of putting it back into the intake tract. Oil is heavier than the air moving it, so the oil drops to the bottom of the can while the pressure moves into the intake ( minus most of oil ). They can be used anywhere oil is not desired like mentioned in air compressors, air suspension, etc.
I like the clear bottom model as you can see when you are pushing oil and how much, although the billet one is beautiful!

 

Or in an LSx based car/truck because the PCV system truly does SUCK.
