Check valves from forced induction engine

[Invid]

Well after a rather unsuccessful trip to the wreckers I'm still no wiser as the where to source these parts.

I need to source two valves; one for the oil breather hose to the crank case and one for the vacuum line to the brake booster; to stop the supercharger from blowing positive pressure into the engine where it shouldn't be blowing. Can anyone suggest an engine that these valves can be sourced from?

Thanks
Seb

The crank breather has to be plumbed between the air filter and the turbo with no valve, any turbo car will have the brake valve your after just make sure it's fitted the right way round

Thanks Rodi, the engine is supercharged not turboed. The crank breather hose ran into the intake plenum and I've had to put a oil breather filter on and block up the hose on the plenum. Would like to run the hose again instead of venting to atmos. Any ideas, would a 4AGZE have something suitable?

what about a reservoir and check valve from something like a diesel hilux ? then you get a reservoir too. they're not highly prized so should be cheap.

Is the throttle body befor the supercharger?
If it is, just plumb in the brake vacuum and the crank case breather between the TB and the SC

Just get the brake booster line check valve from a brake shop. I replaced my plastic one which didn't like 20psi with a metal one for about $10.

As noted by Rodi for the crank breather, just plumb it in post filter pre charger. Don't run it with a check valve to the maifold because then you'll get pressure build up in the crank case when on boost and the check valve is closed = oil leaks and fuked seals.

breather has to go before supercharger, PCV valve goes between rocker and inlet, any pcv will do this, any oneway valve for the brakes

As YLD-16L says use a check valve from a brake booster line, I use a catch can, before the catch can I used a brake check valve no problems

From memory R33 gtst have a inline check valve u can use
