Low oil pressure
 

I took the supra out to an empty parking lot and delivered a real beating to it.After about 10 minutes and a lot of attention I decided I should leave before the cops came ,but I noticed I was reading zero oil pressure and the temp was higher than usual.I shut down and checked the engine over and it was purging a lot of coolant.I tried to start the car just to put it in a parking spot but it wouldn't start.I went to dinner and came back when the car was cold ,it started after some effort and the oil read about 18lbs (as it usualy does) and I headed home.When the car got to operating temp the pressure got very low ,about 3-5 lbs.and the car died just outside my driveway and wouldn't start again untill it cooled down.I was told that if I just changed the oil it would likely cure my problem ,but that sounds too easy to be true.

Also ,would it be possible to remove the engine mouts and jack the engine up enough to drop the oil pan? If I could change out the bearings down there without removing the engine I would be a happy man :P

wow, you know, I recently got my supra running after the mhg job, and when I did I swore I would not treat my supra in that way. but many times I've had to eat my words. actually today I gave a 06 mustang gt a run for its money.

the point is ......darn, I cant believe you gave your supra a beating....
any ways, many vehichles have the fuelpump circuit through the oil presure sensor switch. but the most likely cause of your concern would be worn internal...good luck dude..

it actuallly sound like it needs new rings and possibly bearings. just yank that motor outta there and start rebuilding it. me and my brother just got our running good last night, and we only are hitting 4000 rpm until after the first 1000 miles and let me tell you, WOW. that car is just plane insane.

Was hoping to put off a rebuild till next winter ,oh well :P Since I plan to use the car for autocross I wanted to see what it could take now so I didn't spend the summer wrenching away.
