Im my mechanics class we have been working a friend of mines car. Its a 81 Celica-Supra, inline 6. Its a fairly straight car and what not, she likes it. She brought it in complaining that it was pulling right BADLY, and trust me, it was very bad. We could hardly move the front right wheel around with the car on the hoist, my initial thoughs were blown up wheel bearing, weather it being the inner or outter. Turns out thats not the case at all. She had it worked on in the other mech shop at school previously, they did a front brake job to it. Well, i removed the brake caliper, and pulled on the rotor and removed it as well. Two bolts fell out from behind the HUB and Dust sheild, im like WTF is this..turns out the wheel hub was helt onto the rotor by 2 bolts, and the other two had come loose and were spinning around in there catchin on the 4 bolts holding the dust sheild on. This could of been a serious problem had that wheel of locked up on her.
Okay, so we re turned that rotor, did the brake lines fixed the problem. She asked me if could check for a coolant leak, i did, and i found one, a very slow leak at the vacuum actuated heater control valve mounted to the passenger side of the fire wall. She complained it overheated on several occasions. The teacher started it up to move it, as he was moving it, i noticed drops of rusty water on the floor, coming out of the tail pipe! This rusty water then took a more greenish shade, the it slowed down as the exhaust turned thick white. Uh oh my thoughs are her headgasket is done to this world! The oil is not milky however. So tomorrow im going to pull the plugs on it and inspect them for signs of water/coolant contact. Any other test i can do to it? I doubt its an intake problem on this vehical.

Blown Head gaskets happen about once a week on the old straight 6 toyota engines.

lol, maybe she should buy two, carry one around for a spare! lol

Funny you mention that. My friend did that with his Mustang he used to have. Whenever he would blow it on the street he would change it right there. Hed have it knocked out in about a half hour.

Well, we confirmed the headgasket for sure today. We pulled all the plugs, and #2 was crudded up BADLY, so we screwed an attachment in the plug hole and shot compressed air in there, sure as hell coolant burped from the rad cap lol.

how did u screw it up???

we didnt screw anything up.

I think he meant the compression tester attachment....

ohh, k, what it is, is the compression hose attachement without the gage on the end, in its place is an attachement for an compressed air hose.

Arn't we glad we have cast iron heads and block on Bonnies?
We also have a 87 Supra in the family straight 6 7M-GE with aluminum head.
Makes me wonder when that jobs going to come knocking.
