Removing Oil Pan

I need to check my oil pick-up tube inside my oil pan. What is the easy way if there is to remove my oil pan? I have a stock '96 ZJ Limited 4x4 with a 318. Thanks for any help, Mitch

Why do you thing that the pick-up tube is leaking or partially clogged?

The reason why I ask is; I would suspect the oil pressure sending unit before I trust the oil pressure dash board gage.

Independent oil pressure gauge agrees with dash gauge. The pick up tube screen needs cleaning. I was hoping someone could tell me if I can drop the oil pan without taking motor loose before I try and it not work. Has anyone dropped the oil pan and if so what was the best way? Thanks Mitch

IIRC (its been about 1.5 yrs), on the I6, you have to remove the flywheel cover plate (where the starter is), the starter, you have to raise the engine (maybe not if you have a lift, I did this before lifting my jeep) which means disconnecting the motor mounts, then remove the pan bolts.

I thought I could do it without raising the engine, but the pan hits the front axle housing and hangs on the oil pump pickup. The V8 may be different, I'd suggest looking at the Haynes manual, as it has all the needed steps with nice pictures.

Oh, and make some "pegs" by buying 4 bolts that will screw into the pan mounting holes to assist in reinstalling the pan - it helps a TON.

Oh and I also had to disconnect the exhaust...

its a bit of work, I did it to replace the rear main seal.

The Jeep repair book say to do exactly what you said plus remove the starter. I have found that the book sometimes makes you take steps that are not needed but sometimes you have to do it by the book. Thanks, Mitch

Yea, lifting the engine was kind of a pain, but not terrible... I did it using a stack of cement weights, the good ole jeep bottle jack, and a block of wood underneath the harmonic balancer.

for anyone doing this to a 4.0, you might want to look into replacing the o rings in the 90 degree angle adapter on the oil filter, if you're having leaks around that area. Easy fix, you just need a big torx socket and the gasket set (like $5 at the stealership). You can only do this with the engine raised b/c the adapter is too close to the frame rail otherwise.
