thanks guys, mm well yea i was planing on getting some heat wrap to put over it. something weird happened today though. im driving and it was a pretty long distant drive. the coolant resivour usally overflows on trips like this but it didnt on this one. so on the way back i was stuck in bumper to bumper traffic and then i noticed my engine temp was on H and almost in the red zone. so i quickly pulled off to the side checked it out. spit on the turbo and it wasnt running hot enough to sizzle the spit. but the valve covers where really hot. next i checked the coolant resiviour and it was full and looked like it was about to overflow, so i waited a little longer so i could take off the radiator cap, it was steaming when i took it off. lots of pressure but there was no coolant visible.

now i know i need to purge the coolant system cause it does the waterfall sound during warmups and after sitting at idle for a long time. but what do you guys think is going on here, mainly the overflowing of coolant. cause im getting tired of buying coolant to put in there almost every week.
