Default DIY oil pan gasket?

Does anyone know of a DIY for the lower oil pan gasket? (the smaller one that has the drain pug) Mine is leaking and I need to change the gasket. I understand that it's just a sealant that you can get from Lexus/Toyota. It look simple enough, 16 bolts and 2 nuts but I wanted to make sure there aren't any other parts I need to remove before doing this. Thanks

Not sure as I've never done it with a 2J in the car. Just be forewarned that you will have to pull the pan off to clean off the FIPG which is somewhat of a pain to remove. The FIPG from Toyota comes with a little tool to separate the pans...sort of like a little knife. This really helps to keep you from warping the pan lip. Both surfaces must be absolutely clean of any oil and old sealant for the FIPG to work properly. And use the FIPG (Form In Place Gasket) material from Toyota or Lexus (much better than the RTV stuff at the local auto parts store).

definetly get the FIPG from toyota, the parts store stuff isn't nearly as good..

but yeah just drain your oil, removed the bolts and nuts and make sure both surfaces are real clean, i use a razor blade to scrape the old gasket off..


also when tightining the bolts/nuts use a criss cross pattern, tightening them oppisite from eachother, i'm not for sure how much they are supposed to be torqued but definetly don't use brute force, i think on oil pans for most cars it's 9 - 12 tq..

Any tips on how to separate the pan once the bolts are removed?

I just wedge a screwdriver in there and hammer it till the pan separates. Sometimes you will bend the pan just a hair, but it's very easy to straighten back out. I use the stuff from the auto parts store and it's been perfect every time. Make sure you get the grey one, it's made by Permatex and called Ultra Grey. It's pretty much a exact match for the Toyota stuff, but it costs less. It's resistant to damn near any type of fluid, coolant, and heat in the engine. Make sure you clean off all of the mating surface so they are SPOTLESS, and then use brake cleaner or alcohol to ensure that there is not one single drop of oil on the mating surfaces. If it is not absolutely clean, you will have a oil leak develop from that spot.

I agree with Jeff; Use the Permatex Ultra Grey.
