84 CJ7 Stuck Oil Pan

I'm new to Jeeps, but had always wanted one... I got one... Been fixing more than driving.

It's got a 258, stock. I have read every thread on the internet. I'm attempting to replace my RMS. I've read all of the RMS threads on multiple forums. I pulled the passenger motor mount and removed all the bolts from the pan but the thing won't budge. I've tried the wedge a putty knife trick, the pry bar, beat with a mallet and a hammer, done pull ups from the skid plate... everything. It's won't budge. Ideas? Thanks!

Bigger hammer?

Sounds like the last owner did a great job sealing it with RTV. You're gonna have to get in there and break that seal with a putty knife, and you may wind up replacing the oil pan after all is said and done unfortunately.

Thanks! I'm not worried about the pan. I already have a replacement one as the current one took a hard hit somewhere and is dented. I've had a hard time getting the putty knife in because of the lack of room to hit the back of it with a hammer. I've thought about drilling some holes in it and attempting to "winch" it of with some brilliant rigging job to get downward force on the pan. Any advice on good or bad idea?

I read on another, inferior forum the idea of putting a jack under the bottom of the pan and jacking it up tight, let it sit, and see what happens.... I'm currently doing that.

Random question - Does the flywheel inspection place have to come off for the pan to drop? It looks like mine (plate) is bolted on through the bottom two bolts AND the bolts that also bolt on the clutch piece. I pulled the bottom two bolts and loosened the two bolts holding the clutch piece. The plate would swivel a bit, but not come totally off. It doesn't look like it has to come off.

You might try putting a board on pan and a small hyd jack between frame and board.apply some pressure with jack and hit pan with heavy mallet. I haven't used a jack before but have had buddy hold board on pan and hit board with sledge hammer. Board will protect pan

I use a 1 inch wood chisel for those absolutely glued on pans or valve covers. And if you sharpen them to a real sharp edge, they do great at surface cleaning of old gasket material.

This is the kinda whiny crap I would expect to see in the JK forum. We drive rough riding, leaking, gas guzzling CJ's. Rattle can it and throw it in your Jeep.

as tito said use a wood chisel,
its flat on one side so it should not damage your motor block surface and place all the pressure on the pan.

try to find out what the po used to install the pan and be sure to not use that material again.
he was very confident of his work, that he would never have to go back in there again.

I am not that confident of my work, as I have had to (lick the calf over) a few times over the years.

I would bet the PO/shop used weatherstrip adhesive. That s**t is the most nasty stuff to use on gaskets.

No. It does not need to come off unless someone bent the thing and its interfering with the pan rail in the rear. You can shine a light up between the two and look neither should be touching.
