Advice sealing crank case/oil pan.

Postby I'm luving it » Sun Jun 16, 2019 11:29 am

I installed the 4x4 oil pan on the diesel a couple months ago. Used RTV (Black) on the sides and proper corners (per the manual). I also used the correct rubber sealing pieces for the front and rear of the pan (from Jerry). Almost immediately the front and rear where the rubber goes started leaking almost right in the middle. The sides are dry. I torqued everything to spec. Going to try to and seal it again. It’s currently leaking too bad to drive.

Anybody out there have any suggestions this is a pain?

Did you put RTV in the groove on those main caps? and put rtv where those seals press up against on the pan?

I did not put it in the grove. The manual only called for it around outer edge and corners were rubber seal meets. I will try that next time. So light coat RTV everywhere....

I've never done a pan gasket on a c223 but I have seen at advance Auto that there's different rtv for different applications. I've used one type made for exposure to transmission fluid. Purple tube I think. I used it last year when reassembling a mower hydrostatic transmission. It held up great

Interesting. I believe in my 82 manual it specifies to put it in the groove. I also put a rather generous amount in the corners against the caps. A ford I rebuilt had the same kind of thing. Really put a lot of the crap in there, doesn't leak a drop....

Well I removed the pan again and resealed it with Ultra Black Sealant. I applied it generously all around including around the rubber seals on each end. It didn’t leak for almost two weeks.
Then today it really started leaking. It’s leaking from the ends where that rubber seal is. I cleaned it up then started the truck and could see the oil leaking out.

I definitely am tired of this problem. Ideas?

You are using gasket rubber or some silicone, if you use silicone gaskets do not tighten everything, adjust it a little and after 15 minutes you finish tightening then the gasket will be dry and the tightening does not take it

Alright so far so good for 100 miles. After speaking with Jerry and a couple others. This is what I did.
1) Had the pan flat surface taken down to no more than 10 thousands.
2) Cleaned up the front and back sealing surfaces (where the rubber seal goes)
3) New Seals
4) Applied a light coating of Toyota oil pan gasket sealer.
5) Tightened all bolts to max recommended torque.
6) Tighten in a Star Pattern
6) After finishing let truck sit for two days

I'm luving it,
I am loving it, that spotless, shiny oil pan. I can't even imagine my filthy, oil covered oil pan looking that good. Glad to hear you met with success! These engines seem to require a lot of attention to detail for a good seal on certain gaskets, according to site posts, and personal experience. Thank you for posting the "formula" for this one.
