Catch Can Routing....

[CarlC]

I agree with Don. Is that small filter your clean air side of the system? If so, instead of the filter it should be connected to a port past the MAF but before the throttle blade.



Also, the threaded fitting on the top of the canister likely should be plugged or else it's just a big vacuum leak.

Then there's this: "allowing oil to outflow if the oil overheats." Can you please clarify this point?
