leaking engine
 

I have a 86.5 mk III with a 3.0 engine. The fracker is leaking in the rear of the engine. Riverside Toyota of Tulsa says they have to pull the engine to fix the leak. They want 3k to fix it. :nuts: What could be leaking between the engine and firewall? Yes these are the same people that missed the leak in the rack unit after fixing the pump. :rant2:
My problem is do not really know the 3.0 engine very well. I did some work to my 2.0 liter engine the Japanese version. I can not think of anything that would be leaking with the exception of a cover for the cams? Think old age has affected me. :p

There is an oil seal and gasket at the rear of the engine (see pic below) this is where the crankshaft end connects to the flywheel or torque converter, depending on whether you have a manual or an auto box. I would definitely check the cam cover seals and possible the sump seal for any oil leaks before assuming it’s the rear crankshaft oil seal. Also the 7M engine does slope back at an angle (probably about 5 degrees at a guess) any oil leaks will eventually find there way to the back of the engine.

Bill UK, thank you for your information. I had the rear seals changed when the clutch was replaced by Toyota. They were also suppose to change the cam seals as well. Yes I suppose any engine leak will migrate to the rear of the engine. It is a good size leak and am annoyed that they did not fix it.
I would fix it myself but no longer even have a floor jack. Guess I need to give it the once over myself.
Thank you again for your useful information!

rear main seal...
 

it most likely the rear main seal ive had the same problem. you said you replaced it put the truth is it probably wasnt done right i would try that first because its easy to access and the seal is fairly cheap.

I let Riverside Toyota of Tulsa change the rear main seal when they changed the clutch. You would think the dealer would do a proper job. I know where not to buy my next new car. Suppose I could bring it by the competition dealer. The maintenance "adviser" said something about a seal on the backside of the engine leaking. He said this to me not long before getting sacked. What could he be talking about? He said the engine had to be removed to fix it.

There you go ! all the likely places where an oil leak could accrue; I’ve marked the oil gallery plug only for reference, its very unlikely this would leak.

the dealer messed up
 

Got a chance to look under her at the wheel shop. She is leaking from the rear main, the oil pan, the oil plug. Talking with the owner of the shop he thinks the main bearings may be bad. This would cause the seals to leak.
My gripe is they were suppose to repair these items. You would think the Toyota dealer would do a proper job. Well gotta run, school tonight a biology exam :p

sounds like someone is entitled to a free repair.

Talked to the General Manager of the dealer. He was unable/unwilling to help. He is passing this off to the service manager or the person I have been dealing with on this problem. If I felt better would do the work myself. Could a worn out bearing cause the seal to leak? My thing in life is aircraft structural repair and not piston engines. Even that has been some time ago, the Corps has me warming an office chair now :p
