This is a possible reason for your cold start issue although I doubt it since the S2 IM doesn't have a port for the pcv to connect to the IM. I am not sure it would affect it in that regard considering the pcv does not allow air into the valve and it only releases pressure.
I have the air assist valve plugged off with may be the difference for cold start idle.
It will leak out a mixture of air/oil/fuel which would normally get sucked back into your motor through your oem IM. Not a constant leak but when the pressure builds up it will release that. This is why the oil CC is best.
Also, nothing should get sucked back into the pcv port, it is the way the valve designed.
after looking at the thread above that you linked, i wanted to say that i HATE that part of my mani. it leaks coolant from that gold bolt. the top of the mani, and the furthest to the right bolt that has a hose in it. is that what you blocked off? i should link you my thread that i started on that problem.
Ya, link me to it, and yes, coolant will leak out of there if your car is warm/hot. If you do this make sure the motor is completely cooled down, I did mine in the morning just to make sure, I hate coolant
ok, sounds good man. i'm gonna end up doing that this weekend. i think i need a new gasket for my mani though since it's still leaking coolant in the lower right corner area. must have tightened the bolt too much.
omg you have your PCV capped off?!?!?! dude remove that immediately. you need to run a hose from the PCV and put a "T" tap into the other vacuum line that runs to the top of the manifold. you need the PCV under vacuum...
