Question Oil Pan Gasket?

I have an oil leak that is bad enough that needs to be fixed. I have traced it to what I think and hope is the Oil Pan Gasket

Where can I find a good write up on changing the oil gasket?

My bet is it's the rear main seal that is leaking Austen, not the oil pan gasket. The rear main seal is a fairly common source of such leaks. You're probably better off having that taken care of by a mechanic. It's not THAT difficult of a repair but when that happened to my last TJ, I just had it taken care of by a tech at a shop. I don't like doing that type of repair myself though I'll handle other leaks like leaky pinion seals, etc.

How do I diagnose if it is the rear main seal or the Oil Pan gasket? I just called my Pep Boys and they have a Oil Pan Gasket in stock for $20.99

I'd probably just clean it real thoroughly and watch it closely until you get a better idea of its true source. My $$$ is on the rear main seal leaking, I've had and heard of a lot of rear main seal leaks but never an OE oil pan gasket seal leaking.

If I were to spray it would water go inside the source of the leak?

When I look up at the oil pan it looks sloppy (orange RTV coming out) is that OEM or Hack? It looks as sloppy as my front Diff (I am still waiting to service my front diff myself)

The leak seems to be coming "Out Of" the oil pan at the very front of the pan. It is a bad enough leak that I can park in a different spot every night to a new leak in the morning. I am going to have to scrub my parking lot soon. I check the dip stick and the level says perfect.

It's not going to be the oil pan gasket, its going to be the rear main seal. It's not that hard as long as you have plenty of time, room and mechanical ability.

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?

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.

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.

You just need a single two-piece RMS. Sounds like the kid at Pep Boys is trying to double his sales volume.

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

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.

From what u described, I'm going to agree with the oil pan leaking. Do not but a gasket at pep boys unless u want to do it again. Get one from the dealership and a small tube of grey rtv. OE oil pan gaskets are the only ones I have ever gotten to seal properly. In order to replace ur rear main, u will have to pull the rear main bearing cap off. It's a 2 piece lip seal and can be kinda tricky to replace the upper half (part in the block) if u haven't done one b4. Once again, get one from the dealership. 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.

So time for a team huddle guys:

Jerry you are the Quarterback, should I buy the oil pan gasket for $20 and change it myself to the obsessive compulsive standard that I operate by to see if it works?

If it is the RMS I would have to change the OPG again.

What should I do?

If it were me, if I am understanding everything you have said and that it's the front, not the rear, of your pan that is really leaking, I'd just go for the OPG. That's the easiest and fastest to change when compared to the RMS anyway.

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.

It would seen to me if the leak is at the (front) of the pan like he is saying then it would be oil pan gasket, but of leaking in rear ( by transmission ) then it could be RMS or oil pan I think we need to know if it is in the front or rear of the engine.

Exclamation

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.

Just saw this post, It is the rear above the drain plug

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.

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.

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

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.
