2002 Tahoe LS 4x4 oil pan gasket change

[SnowDrifter]

It's annoying / messy but not a hard job

Loosen front diff, support with jack

Unclip harness from front of engine

Remove bolts securing brackets to trans lines

Remove plastic inspection covers on the bell housing

Zip the bolts off, mind that there are some bell housing bolts on there too

Jiggle wiggle it off, get under it, push the diff out of the way with your right foot, slide back of pan down and back and it pops off

Clean the fawk out of the mating surfaces. Give the guts an inspection. Do your oil pump o-ring while you're in there (When you seat it, push hard. Takes like 25lbs of force to get the o ring to pop in).

Dab of RTV in the corners (hondabond / threebond) where the covers meet the block

Toss the pan up, spend some time walking it back and forth between the bell housing bolts and snugging it to the block

Torque to spec. Go around again. Go around again

Toss the rest of the shit back together

Go grab a beer or take a nap or whatever. Give the RTV a day to cure before you fill it up

Fill with oil and bob's your auntie


If you want more details / specs let me know

Thanks for the tips! I'm going to get under there and study it first...then plan a day for it.

Have you seen or done this via lifting the Engine? I saw another post about loosening or removing the bolts from the motor mounts and using floor jack on the harmonic balancer to lift the motor for the clearance?? Any thoughs?

I would not do that. Lifting and supporting at the balancer is not recommended and dropping other obstacles down out of the way, IS.

Apparently you only use that area to lift, then use block wood 2x4 I imagine between the mount and
Motor. Just wasn't sure if anyone has actually tried this method or not.

Ok, you are going to do what you are going to do but remember that none of us said to do what you may be thinking of.

Did this recently on an 04 silverado 4x4. We just took the diff mount bolts loose and let is hang a bit and there was plenty of room to wiggle the pan out. +2 on the o-ring. This was the reason my 05 suburban had oil pressure issues. Air was getting in past the o-ring and foaming up the oil when it was cold. No issues after the fix. Good luck with your pan. Make sure you clean out any sludge you have in there before putting it back in.
