Oil pan gasket replacement - Toyota Nation Forum : Toyota Car and Truck Forums

TBayToyotaBoy · 03-23-2009, 01:29 AM

I have what could best be described as a horrifying leak in the oil pan gasket on my 91 GT-S. I got the car up on my huge redneck ramps today and did some investigating, and I noticed that there seems to be enough room between the exhaust pipe and the pan to allow removal without disassembling the downpipe.

I have to make this job as fast as possible (I work two jobs seven days a week so downtime is painful and costly), and I was wondering if anyone has successfully dropped the pan without removing the exhaust...

ya it is costly but i will suggest you to change oil pan gasket of your 91 GT-S car otherwise it will create some major problem.

Dude... what? He's asking if you can replace the oil pan gasket without taking the whole exhaust apart.

OP... i don't know off the top of my head. I took my downpipe off last time i did it.

Sorry.

Okay, thanks for the input. I kind of figured I would have to remove the downpipe but I thought I'd try to cheat...not usually a good idea.

I had to take my lower motor mounts off and remove the brace to get my pan off. The exhaust pipe was not an issue.

That is very good news...I had expected to remove the front and rear mounts (they're rotten anyway) and the crossmembers, so that's no surprise. With older exhaust components, though, removal tends to lead to replacement!

Thanks for the first good news all week (a week that has included this pan leak, an alternator that fried with no notice, and an ice storm that left my fiancee's car wedged cross-ways on my 400-foot driveway's steep hill)...

My 91 gt oil pan came off without removing the exhaust or motor mounts.

Don't buy gasket. Use RTV silicone. Its easier with the front-back cross member out.

Thanks for the advice...I always use RTV on the oil pan (4AFE, 2VZFE, 3SFE, and now 5SFE). As long as the surfaces are uber-clean, it works better than any gasket...

And PittsburghCeli, I might as well remove the mounts because I'm replacing them. It's only one extra bolt up front and one at the rear anyhow (the four bolts holding the mounts to the crossmember have to come off anyways, right?).

I didn't remove the crossmember either. The oil pan wiggled out without a problem.

I guess I'm mostly worried about the RTV sealant getting smeared around as I try to manoeuvre the pan back into place and over the crossmember...I want to get this right the first time!

To be safe, I'll just drop the darned thing... but I'm impressed that you managed it without the extra step.

For anyone else trying this: the pan does NOT clear unless the crossmember and downpipe are removed/dropped. Maybe there are different pick-ups on different years of the 5SFE production, but the screen on my oil pump pickup sits about two inches too low to remove the pan without the exhaust/cross- member out of the way.
