G-LOVE I am replacing my oil pan due to putting a screwdriver through it while removing rust.

I have removed the exhaust, but the bolts and the factory nut holders are pretty rusty too. Any good spot to get them besides the dealer?

Good luck with yours!

JeepmanTJ I had the same problem with my jeep and it was coming from the same spot. The leak was the valve cover gasket and the oil pan gasket. Both were very easy to change. You could have a RMS leaking to. I'm a mechanic I did mine stages because we can only work on personal cars on Saturdays at the where I work. When I did the oil pan I change the oil pump because it was going bad.

To drop the oil pan.
1: Spray the bolts and nuts on the exhaust flange down the night before you do the work.
2: Remove the exhaust pipe.
3: disconnect the ground on the battery.
4: Remove starter.
5: Remove trans cover plate.
6: Now remove the oil pan bolts, and it will drop down out of the way. Drain the oil first.

I didn't replace the RMS it was not my leak. You will see the RMS will be a little more work to install. I had a lift and air tools ,cuts the time in half. Good luck.

SilverTJMike A dealer in colorado qouted 600. Need a flex socket for those exhaust bolts, that was the most time consuming part of the whole deal, removing and installing.

I want Jerry's mechanic!

Austen I just talked to my cousin and I will start collecting my needed parts and supplies so when I am ready for my next oil change we can do this. We will start early on a Saturday in case we need to roll into a Sunday. I am going to start spraying exhaust, 02S, and oil pan bolts now though.

By the way: What does IIRC mean?

Sorry but it was years ago and I don't recall. I had it done in a 4Wheel Parts shop when I worked for their parent company so I didn't pay list price for the labor anyway. It might have cost me $75 IIRC which is probably half of what it would have cost a regular customer.

Looks like its the rear main seal to me
05-08-2011 01:26 PM
Austen After reading the first write up that works, I too think it is my RMS but at least I will be able to scrape my Oil Pan, clean my filter pick up, and anything else in there.

I am thinking about tackling this with my cousin who will tell me up front if we can do it in his driveway.

I forgot that some people refer to the timing cover seal as a front main seal... My bad.

I don't like doing that type of repair myself though I'll handle other leaks like leaky pinion seals, etc.

SilverTJMike Check moparonlineparts.com or other mopar online sites, get up to 31% off list. the mopar seal does not come with the shoehorn piece but those are easily fabricated.

That said, here are some great rear main seal write ups so you know what's going on even if you pay someone for it. If you get as far as the pan off you are 80% of the way there. 15 dollar rear main seal, 3-500 in labor

Must haves: factory service manual and a torque wrench.

Note our 05 LJ the top and bottom seal were identical, they do not have the wings that some of these show.

05-08-2011 01:07 PM
Jerry Bransford Oh sheesh man make up your mind where the leak is coming from. Ok, now it sounds once again like it is the RMS that is leaking as I originally suggested it was.

Just saw this post, It is the rear above the drain plug
05-08-2011 12:56 PM
Austen STOP!!!


I just came out from under the Wranglenater:

The leak is coming from theREAR of the Oil Pan above the end of the Drain Plug where it meets the next thing in line maybe the transmission or the transfer case, one or the other but that is where it is leaking Deff above the drain plug. Now I see what a monster this oil pan is to remove.

Now what do you guys say about what is leaking? I am going to take my digital camera down there instead of just my iPhone.

I wouldn't replace an oil pan gasket without replacing the rear main seal as well unless I knew without a shadow of a doubt the it wasn't leaking. Installing the rear seal incorrectly can cause it to start pouring. If u still want to do this yourself, let me know and I'll share some secrets with u.

Nailhead: I just read your response now. If I do the OPG I will take your advice and get it from Jeep unless it so over priced. I will also buy a tube of their RTV as well. I do not think I will do my own RMS I would have to call on a guy to do that. But you gave me great info!

Jerry: When I say front I mean the side closest to my front bumper, not the end with the drain plug closest to the rear bumper. I have a can of gunk I am about to go down there and spray it. Then I will go across the street to the car wash and spray it the best I can.

Scoob There is a front main seal as well. But you need to take the front of the engine apart to get to it. Based on what you are saying about orange rtv. It sounds like somebody has already been there and maybe changed out the timing chain and pinched the front main seal while putting it back together.

Wallygator He might mean one peice or two piece. Not sure if its an option on yours. But you only have 1 rear main seal.

05-08-2011 12:08 PM
Austen The price for the RMS from Pepboys is: $48.99 (two piece rubber) But now the kid is asking me if I need one or two.
05-08-2011 12:03 PM
Jerry Bransford If you simply spray it with Gunk or other engine degreaser first and then just rinse it off, I wouldn't worry about water finding its way inside. Afterall, you drive through puddles and wet roads after rain wihtout worry.

Based on your belief the leak is at the front of the pan and the sloppy use of orange RTV, that is sounding more like the oil pan and not rear main seal... like the previous owner had the pan off for some reason and didn't seal it properly afterwards.

But since you wouldn't change one without the other anyhow so it really doesn't matter which one is leaking.

Whats leaking is a little half moon rubber seal. Drop the exhaust out of the way, drop the starter down and out. Pull the pan bolts and a few tugs later you will have the pan on the ground. Replace gasket and seal. Re-install and torque everything.
Once looking at it all don't try it unless you KNOW you can do it. If you have any reservations at all, take it to a mechanic.

I can see changing the pan gasket there, but how do you change the rear main seal in that step?
