Re: 04 Grand Cherokee 6cyl. oil pan replacement

I am wondering if the pan gasket is not sealing around the rear main. What type of gasket was it? Did you do RTV or silicone on it?

Re: 04 Grand Cherokee 6cyl. oil pan replacement

I replaced mine and it still leaked in back in the same area. I used a Felpro gasket but tried to torque it by feel since I didn't have an inch-pound torque wrench. I ended up taking it off, putting RTV above and below the gasket, and installing w/ a borrowed torque wrench. Now there's no leaking.

Re: 04 Grand Cherokee 6cyl. oil pan replacement

Thanx Travis and JeepMe for your reply. I used a Felpro gasket it was blue rubber like material with metal eyelets around the bolt holes I did not use any RTV or anything on the gasket that could be my problem. I hate to drop the pan but i guess that is the next step then RTV it

I used the same gasket. Did you use a torque wrench and torque everything down in steps and in a cross pattern? If you didn't and you really don't want to drop the pan, then buy/rent/borrow a torque wrench. Then loosen all the bolts (don't remove, just loosen) and incrementally torque them up to see what happens. You should be able to do that without much effort as all the bolts have easy access. Then if that doesn't work, drop the pan on your next oil change, clean the surfaces, and put some RTV on each side of the gasket.

Also, the repair manual says that you're supposed to apply RTV on the upper side of the gasket at the block/timing cover joints and block/rear main joints. Did you apply RTV there? If not, you're most likely going to have to drop the pan no matter what.

Re: 04 Grand Cherokee 6cyl. oil pan replacement

Frango100 - Thank you for the pdf file on oil pan replaacement.
JeepME - thank you for your suggestion.
I did not use any RTV at all on the oil pan/ gasket and because it is leaking quite a lot ( blue cloud behind the vehicle going down the road).I am going to drop the pan and start over with some RTV. Will let you know how I make out.
Thanx again

If it was me and I was dropping the pan again, I would RTV the entire gasket. I didn't want to put RTV in the appropriate spots only to have it leak again and potentially drop the pan yet again. That's just my suggestion/opinion.

Re: 04 Grand Cherokee 6cyl. oil pan replacement

I had to drop the pan a third time . Found the gasket in the rear around the crank was too long - squeezing out into bell housing/torque conv.Cut it to length , coated with RTV and my leak disappeared.
Want to thank all who responded, you guys/gals are great.
Thanx again
