Catch can question

[theSOB]

Hey guys i want to know what you are using. i want a catch can between the PCV valve on the valve cover and the intake manifold to keep oil out of my recently cleaned h23 IM. any suggestions for which to use? or does it even matter. should i just buy one off ebay? any info would be helpful thanks!

[cb7pr]

i paid $35 and had it dipped in an acid bath for a day. looks brand new

i bought the cheapest catch can off ebay and upgraded the hoses because at vacuum, the hoses collasped,

the can is about halfway full after 5k miles.

[theSOB]

alright. imma prob do that

there are other threads on this topic. I know cause i had asked the same thing before. the info i got was purchase PVC pipe and two caps that fit. get a petcock or raidaitor drain plug and 2 threaded on one end and barbed on the other adapter thing for what ever reason i cant think of the daymed name but make sure it fits nice and snug in to the hose you are useing dont forget your hose clamps and enough hose to mount it where you would like. im still making mine slowly. I hope this helps and i cant remember who i got the info from I will not take credit for somthing someone elses info.

an ebay catch can isnt too expensive. i'd rather just do that than make my own. plus it looks nicer. but thanks for the info

Why dont you just get a catch can from agp-turbo and call it a day. Get fuel line hose those they dont collapse as easy. Attach 1 side to the pvc then 1 side to a nipple on the intame manifold but put a checkvalve in between so that you dont vent back crankcase pressure back into the motor.

isnt the check valve already in the pcv valve?

Yes - The PCV valve is a oneway check valve.

This is made from a air compressor air/water separator that can be found at your local home depot or lowes. Just purchase whatever brass fittings you need and use teflon tape on the threads. This worked very well but I did end up removing it because the high heat and vibration caused the clear casing to crack. I've thought about buying another and wrapping the clear case with duct tape and then putting 1.5" plastic loom around it as well. That should make it last alot longer.

This amount of oil cam from 400 miles of driving so you can clearly see the benefit of preventing this large amount of oil from reaching the intake:

thats a pretty cool contraption. it's too bad it didnt last

I did it and it was less than $25. It works really well, I've had it on for 2 years and it hasn't cracked...you need to route the hoses so that the plastic doesn't touch anything

Yeah, I'm planning to re-plumb it as soon as I get the chance.

ok, go to old navy/ shaws/ modells, get a cheap stainless steel water bottle, grab some 1/4 inch npt fittings at home depot, drill two 1/4 inch holes in the can, put some jb weld on the threads of the fittings and thread them in. you can toss in some stainless steel wool if you want. theres your diy catch can at a total sum of $14 including jb weld.
