In reply to Dusterbd13 :
Yea, I knew it had a small leak. I thought it was from trying to teflon tape some straight threads on on the coolant temp sensor adapter.
I found out i had a leak when I did an autocross in Savanah and they asked me kindly to not go back out on course due to the small leak.
I fixed the coolant temp sensor housing with a Viton o ring (as it is supposed to be). The leak apparently got worse, because when I filled up the system, it started leaking even without pressure on the system. Drip drip drip drip.
