Thanks.

From what I have read, I do bottom out the studs (but don't put too much torque on them). Is this right?

Also, I can only find head studs for the 7M-GTE. I know the engines are mostly the same but I don't know if there are head differences that would make these not work. Do the 7M-GTE head studs work in an NA?

temp problems
 

1. bad fan clutch
You are going to fry your puppy driving it this way

/\ that could also be a bad water pump and/or thermostat. Mine did that exact thing when the stat went bad.

ok well my car doesnt shoot anything out of the tube overflow end. it shot antifreeze out of the radiator car(when it was cold) and out of the tube end when it over heated. i replaced all coolants and everything. hasnt overheated since. still think its a bhg?

i didnt mean when it was cold..i meant wen it was closed antifreeze was shooting out.

hi guys! I have a 1991 turbo that had blown head gasket, symptoms,..coolant overflow all over my driveway every time I drove it! I would overheat,..at stops lights etc...and cool down once I drove off,.but the telltale sign is after you park it the coolant fills the reservoir and overflows all over the ground..had the head gasget replaced along with the head being cleaned up and no problems since...

hi when i got my first supra my head gasket had gone my symptoms was rusty water around reserve bottle all so no heating and then i noticed that coolant level dropped i took to toyota and did emissions test from radiator and discovered there was emission coming out of it and also if you oil in coolant or coolant in oil {milky} it has gone as well

Looks like you have air in the cooling system. MA's are very difficult to get the air out of the cooling system after you worked on them.

An air lock can cause overheating, while in fact the coolant gets out through the expansian container. (not sure that is the right word)

Might help to press the tubes intensely several times when the car is hot (keep heater system open) to press out locked air bubbles.

drive it on the freeway really quick then check your reservoir/radiator if it is overflowing if it is, chances are you have a blown head gasket. it overflows bcause the cylinder number 6 pushes the pressure back and you know how 7ms are, their head gaskets love to blow up.

ever check the water pump there is a indacating hole on the top side of the pump that leaks water if the seal has gone bad, also check around your intake manifold since it is also water cooled
