h.e.l.p.....overheating

jadeanthony · 08-30-2007, 01:44 PM

we dropped it off again last night, it ran fine all the way over there. When he started it up it pumped out about 1/4 of water then the exhaust was dry, no white smoke. The guy torqued the heads beyond factory specs. We checked coolant ratio, it was approx 50/50. It seems to be an intermittant problem but neither my son and I are mechanics and this guy doesn't take questions well. The proverbial "I have forgotten more than most people think they know" He came highly recommended but now we are in a tough spot. The car does not cool consistantly, we don't know of anyone else around who will touch it, never mind the 4k+ hes got into it. When it runs cool it runs extremely well but he is afraid to drive it because if it is not the HG right now he does not want to blow it again. Right now the guy is talking about re-torqueing and maybe pulling the head off it and having it checked again. I just hope he is using his wallet this time, my sons is running dry on a car he can't drive........is this the love/hate relationship I hear about on the supra????

does it bubble over and spit water or is the temp gauge just saying it's overheating ?

do you spit water onto the intercooler from the over flow tank upfront by the drivers headlight ?
do you see water ?

yes ....and yes. When it overheats it spews everything out

just as a concern when retorqueing use arp bolts not the factory ones the stress may cause them to snap in half and then you will have a bhg

also have you ever burped the system? that might help just going from what happened to my girlfriend's na

look at my block and you can see why just replacing the headgasket might not be good enough

not being a mechanic, I assume it is because it is an uneven surface correct? But if the guy took the head off to replace the gasket, wouldn't he have seen that the surface looked like this and therefore would have had it ground or whatever they call it...to give it an even surface............did this guy just cut corners and charge him big $$$$ and not do the job properly????

the picture makes it much easier to see the damage,
you can barely feel it let alone see it .
the combo of the bolt pattern and the low factory spec of 55 lbs is what kills 'em

it's a long slow death , if it really goes long and slowly you get serious block damage from
the water just sitting there between block and head and a wet paper gasket for years .. oh lets say
20 years
