Is it supposed to vent to atmosphere or can I use the jdl catch can? I never got instructions from jdl for the catch can, I called them and they said they didn't have any either...
how are you guys running your catch cans and what brands?
2) The blow off valve is open when at idle, but closes when some throttle is applied. I'm assuming this is how its supposed to be. But to me, why would it be open. Wouldn't it suck in air from the engine bay when theres a possibility of dirt/dust going in and going through the throttle body?
3) I have the fbm oil cooler. The sandwich plate seems to be leaking. It was sealed with that liquid teflon tape type thing, but still leaks. Not sure what the reason is for it leaking. The fittings are in all the way in.. any ideas?
4) I had all my hot pieces ceramic coated by a local place, and it seems like some of the piping was either shrunk or gotten a little bigger. The wastegate is VERY close to the crank pulley. Almost 1-2 mm away from touching. Anyone have this issue or know of a solution?
5) The dump tube is sort of short and dumps very close to the radiator fan harnesses? I'm thinking of making the dump pipe a big longer so it can dump outside of the engine bay.
Any help or ideas would be great! Thank you!

1. Sounds like a vacuum leak. Sounds like you hooked up the hose off the back of the intake manifold which is not correct. You connect both hoses from the rear passenger and front driver side crank case and breather.
2. You need a stiffer spring. The BOV should be closed at idle. The correct spring is an 11 psi with some washers (I have some I can mail you) or a 12 psi.
3. Tighten the fittings or remove them and apply more sealant and give it another shot.
4. I have no idea on that one.
5. Sounds like a good idea. I would make it dump underneath the metal panel. Are you sure you have your wastegate installed at the right angle? Seems 4 and 5 might be related.
