smoke comming out of the valve cover breather and overheating...
i turned the mbc up from 10psi to 12psi and afer a hard 1st to 2nd i stopped at a light and my temp gauge went to about 3/4 hot. then when i got home, i opened the hood and the radiator fan was working but there was smoke comming out of the valve cover breather and the catch can breather.
while in idle the temp went back to normal but then started going up just about half way. what the ---- could it be? head gasket? fried rings?

check your oil and coolant to see if they have mixed any.

no oil in coolant or coolant in the oil. after 15 minutes of the car being off, i checked the oil, the radiator fluid
and no mixed fluids. and the oil level was right where it was 2 weeks ago when i did an oil change?
i turned the car on and the radiator fan came on in less then 4 minutes cause the car was stil hot and i left the radiator cap off so i could rev it a little and see if water flows and it does. wtf? could the hg be just a little fucked up? well i turned the boost back down to 10psi 
any opinions on this crap?

do a comp. test and a leak down test, i thought my ---- was fucked b/c it was smoking on decel, after a comp. and leak down test, i figured it was my turbo smoking, took the turbo off and inspected it, it was fine, turned out to be an axle seal leaking tranny fluid on to the firewall and dripping on the dp :P moral of the story is, it could be anything.

i haven't taken it out for a spin yet. but when i checked it i kept the rpm at 4k in neautral for a good 2 minutes and then i looked to see if it was smoking from the breathers and it wasn't. i'm gonna drive it real soon to check it out.

Not sure about the temp but also check your pcv valve. Yes do a compression check. I have also heard of head lift under boost but fine at idle so that sort of rules out the excesive blow-by at idle. Ring land maybe?

Re:smoke comming out of the valve cover breather and overheating...
i don't have a pcv valve. i emptied it out(pcv valve)and i put it back in and ran a hose from the pcv valve to a catch can that just has a breather hole and is not connected to the intake on the turbo.
