i came home and thought to myself (sober) wtf... i have gone through everything and replaced it. and was still not working.
so i figured im better off working backwards from what i did first, maybe ill find something.
just for the hell of it i took that tstat housing apart one more time ( takes like an hour to get in off... really stupid spot/set up for it and ive done it probably 5 times, a lot easier with exhaust manifold removed, etc etc )
and, dont get me wrong - this black cup or sleve that goes in after the tstat, only works one way. theres a slot in the side for coolant to flow into the heater core, and last time i took it apart it shifted during installation and was blocking the passage.
and no lol, my h/g was pushing combustion into the cooling system. i messed the tstat housing thing up when i was putting the head back on.
i was so close to taking up drinking after i got the h/g in there and i still wasnt getting heat. alls good
am i little embarassed? sure after taking half my motor apart, getting it back together , starting it, and i still had to come make a post online. stupid small mistake, what ever
