Oil Catch Can Tips

[arronm]

Run two full oil separators and dont vent anything, then no issue with the police. Had mine looked at a few times and no issues...

You wouldn't run a custom breather setup to the pressure side of the turbo. You'd either dump it to atmosphere or run it to the intake pipe before the compressor.

 

Yes this is the correct way. The check valve would be used if you dont have a blow off valve because it would return to the compressor housing and would have the potential to enter the catch can.

 

You would never plumb it to a boosted section of the system.

Well you do, you just use a one way valve so you dont pressurise the can under boost. that's how my PCV is set up.

[Puffwagon]

You do if that's how you set it up.

 

I wouldn't do it that way but it's not to say that it wouldn't work if that's what you wanna do.

 

I doubt anyone has ever hooked up a few map sensors to check the data. There's always an exception but apart from that it wouldn't hurt to run one.

 

There's a lotta cats being skinned lately

Assuming you retain the pcv then yes.

 

But when going for big power and boost you have to delete the pcv. The oem setup wont flow enough through the vent at WOT so the pcv has to go. 

 

PCV systems are a sh*t design and have no place on a hard core engine setup!

Pcv=positive crankcase ventilation.

 

Pcv valve is probably what you mean. 

 

If you delete your pcv then you are sealing your crankcase and that won't work at all.

[Typhoon]

of course it will

 

when you vent both to atmo the pcvV is deleted and obviously the cranks not sealed.

 

if you run a three port can to draw just after the air cleaner and before the turbo. the pcvV is also deleted becuase its not used.

 

 

How wont it work?

 

of course it will.

Lol sorry to be pedantic but sometimes you gotta be as there is a big difference between what you wrote and what you meant. 

 

Anyways this conversion is kinda pointless.

I understand,

 

I should have worded it correctly, and attention to detail is a great thing mate?

 

 

Race cars and high performance engines all use pcv systems. Most run dry sump systems and incorporate vacume pumps and other means to assist in venting the crank case. 

 

PCV valves suck balls and are a crappy design that I dont like! ?

Yeah it isn't the best for performance.
