thats what i think is happening, if you look on my profile pic album you can see the dumb o2 sensor position...
but ever since i did a slight rad flush, it hasnt happened. and yesterday, because i just insured my samurai for 3 months with a new hg, and carb. i juts didnt care so i took my supra, for a 1 hour drive to work. didnt even get close to half way temp...
maby i had a bit of a block in the system... also i was about 2 liters low, possibly wasnt enough water...
either way, a piece of the casting, just a thread for a bolt, broke right off my head.!!! so i probly have a few cracks in other places aswell, and ive been rebuilding another head i own.
