overheating? no water?

[Finnon]

thanks for your inputs finnon, i already checked the water pump, seems to be fine but replaced it with another one just in case [already had one in inventory] so yeah idk when im actually gonna jump in the hood to check things out due to the hectic work for the end of senior year [highschool] :icon_neut

no problemo young man. when ive heard of problems in the past there seems to be an issue with the blades on the pump coroding away. in the uk we can buy pumps by a manufacturer called quinton hazzel. they have cast iron blades so should last longer than oem units.

seems funny how you guys all have supras at high school.

good luck with the car

the problem i had with my 7mge is that my throttle body is cracked where the coolant lines are, and since i have a catch cat hooked up to the one port (where the vavle covers attach), my catch can filled with water and then i lost it all because it leaked out of the catch can. so i looped my coolant lines on the TB and no more red zone for me!

Thanks for the explanation Cuel!(BTW..Love the Avatar)

But, why in real world applications do many people get away with having the head shaved, and slapping it back on, with little other work. I don't say this to argue with you, just trying to get good insight from someone I trust as very knowledgeable.

Sorry it took me a while to answer this, I missed your question.

The answer required for that question is, honestly, beyond me. The technical reasons aren't known to me, as I'm not really an expert. I've wondered what anealling was myself, and went and looked it up. Found the same answer as you, just went a little further, as I wasn't familiar with some of the other terms used in the definition. To be honest, I still don't have as firm a grasp on it as I'd like.

I suppose it could be that most people catch it overheating, and get it shut down in time before any serious damage is done.

I've seen both ways. The people who shut it down when it overheats(or as soon as they notice it), usually get away with a gasket job(mill the head, test it for cracks and insure valves are sealing at the seat correctly, correct the problem that caused it to overheat). The other people, the ones who either run it hot and refill it numerous times, or drive it hot until it quits running, get a new motor. My machinist spots them pretty quick, as the head will be severely warped, and most of the valves no longer seal right. These same ones will, usually, have issues with the bottom end as well. Seized rings, trashed bearings, and some serious scratches and grooving in the cylinders. I've had to learn to look for those things the hard way. I usually figure if it won't start and somewhat run(without knocking), it gets a motor. If it'll start, and run by itself with minimal complications(slight miss, gets hot quick, fails block test), I'll attempt a h.g. job.
