Catch Can Really Works!

[Mean Green]

I have a Greddy catch can installed on my GT. This is a pic of how much oil the catch can has captured in four months. The oil is in a 20 oz Dasani water bottle. I figure that's close to 9 oz of oil that was stopped from entering the manifold. One of the best mods I've done.

yep...pretty scary isn't it...it would probably be a little less without the higher boost, it tends to create more blow bye

I think that the catch can isn't good, if you want just a little more power, and the system was designed that way is to have a vac. on your oil system , as the factory has done your turbo has a lot of blow by and the oil vent lets it out, when connected to the intake you have a vac.on your oil pan , this will let your eng run better and yes you will have oil comming into the intake and it should (not a lot but always ck. your oil level) if you put a inline filter, to catch the oil but let the vac. work it will be better. you will see. and comments on this as i am repeteing what turbo mech told me.

Wow, capital letters, periods, and spaces would go a long way to turning this into a coherent post.

I used a campbell-hausfield oil seperator, some npt fittings, and zip-ties on my last car, will probably buy another one for this car.

Jim, the question you can ask your turbo mech is what is the benefit to having all of that oil dumped back into the manifold? With the Stage 1 and later the Stage 2 the blow by is increased over factory specs. The pcv vents into the catch can and then vents into the manifold minus all of that oil. [:I]

This coming from the man who is boosting 21psi with no added fuel.

The catch can is not a dead end the way I undertand it. It is simply a resesvoir (I butchered that word) to collect oil, rather than spray it all over your engine bay (for those with modded intakes).

Am I retarded or is that it?

reservoir....

Catch can should be in-line with the PCV hose, hopefully to allow gas to travel through the hose and prevent oil from making it from the crankcase into the intake. Those of you who have emissions checks must not dump the crankcase vapours to atmosphere or you get fined when you do the e-check. Believe it or not, burning the crankcase gases is/was the biggest emissions reduction ever discovered.

very true 3Bar, i got a nice FAT ticket ($380) for having a crank case breather filter...but i modded my intake to make it carb legal.

Sakigt, being this is my first ever Turbo car, I am learning every day, (thanks to all of you) , after owning lots of 60's high performance cars I have found a new toy,THE TURBO Pt Cruiser, also owned a 2001 non turbo Pt. and the best way to learn is to ask questions, what may sound stupied to some is not to the person asking, or the person would not ask. and I am or was running 18 lbs on the street and 21 on the track, removed everything and got my pcu replaced , would like to run at least 1000 miles before making any changes, Merry Christmas and a happy and healthy new year. Keep up the great work.

yet many manufacturers of catch cans say not to put it in the pcv lines, perrin for one...
