Trouble Shooting Oil Low Oil Pressure (7MGTE)

kcahrens · 03-16-2011, 12:12 AM

Also, If the oil pump is to blame here, Would an OEM replacement good, or are there aftermarket, more efficient solution.
Intuitionally I would believe that the OEM oil pump would be fine, considering that the 7m is meant to be a high volume, low pressure engine.

Yes it should be alot better since it will have no wear and closer tolerances. I think the upgraded pump is a good idea if you are going for higher hp and want the extra protection. But 190k is alot when you consider that you probably don't know about the maintenance done on the the car over its life.

awesome. Is there anything other than on oil pump that it could be? (I guess that chart lists other causes.)

And great... I had a feeling that this wouldn't be fun or cheap.

Do I have to worry about replacing anything else besides the pump when upgrading the oil pump? (will having more pressure hurt anything)

another question I have been pondering is what oil is best for my Supra? With the high miles, I want to take care of my engine for the next couple of year while I decide what I want in a rebuild.

Yeah, I really don't, from the previous owner, he said that he kept up on it really well from 70k to 190k. (2 timing belts, changed oil religiously, ect)
but I do want to rebuild the engine in the coming years.

There should not be much in the way of the oil system other than the pump that you should have to replaced. But a rebuild is probably not a bad idea. As far as oil I have heard good things about amsoil although they are alittle expensive. http://www.amsoil.com/mygarage/Produ...TOYOTA+SUPRA+0
I have not used there oil yet but the gear oil works very well in my 6spd in my celica.

would using a synthetic oil be bad for an engine with high miles like mine?

Do you know what I should look to replace along with the oil pump?
