im into making my own oil catch can... ive gone thru like 5 pages from searchin... came up with the basic concept of it... now i came across some1 mantioning the open loop method ... when u just dont hook up the line back to the manifold.. and leting the vapors out of the engine .. does this really work???

 

no, because you need the vaccuum that the manifold provides.

 

ty... now is it really recommended to use steel wool in the can?? has any1 else use any other material?

not the real fine steel wool. but the thicker, stainless steel stuff.

you can use other materials, sure... but the steel wool is just easy, cheap, and available lots of places.

 

ty

 

stainless steel wool can rust and break apart, (even the thicker stuff) I wouldn't use it.

You can pick up plastic gutter guard for cheap, and packed together it will filter well. If you want the oil catch can to vent into the air, you need to run with out a PCV valve, and use a slashcut tube in the intake to force air into the crankcase.

Not the best way to do it.

 

wouldnt the plastic melt??

 

no, the catch can doesn't start on fire.

 

yes i know but it does get hot... have u done this urself??

ok so wuts proven to work... from personal experience pls... some say steel wood some say that plastic thing.... wut works???

 

Alluminum can rust also, I personally would not want to be sucking rust into my engine.. but thats just me.

As far as heat, the vapors are coming directly out of the PCV valve, and what is the PCV valve made out of?

Plastic.

Oil vapors are not going to get hot enough to melt plastic or even warm up a catch can.

 

if the can is made out of steel or aluminum.. dont u think the plastic would melt.. now yes the pvc is made out of platic.. but its way thicker than the stuff u puttin in the can

sorry but i have to say something....
its wool not wood....and its pvc not pvs.

 

oooohh fukin god ... u know wut we are talkin about... mystakes .... do any1 in here know?? or just let this **** die.. and ill post it somewhere else

 

The melt index of ABS plastic is around 220C, thats over 400F. Its not going to melt, oil vapors are not nearly that hot. Christ.

I have made steel and alluminum catch cans, both using plastic baffling, which #1 hasn't melted, #2 the cans have never been hot to the touch even after 20mins of lapping at HPDE events.
