Leaking oil...

[SiberianPatrol]

After crawling up under my patrol for more inspection this past week, I noticed the oil pan had previously been cracked and fixed with some welding. However it is still leaking oil and to be on the safe side I am having the rear main seal replaced as well as new oil pan and gasket.

Problem is, we don't have very many wreckers over here in Siberia, so the oil pan is hard to come by. In na find the gasket and rear main seal without problems, but the actual oil pan is next to impossible. I've got a few more places to check before my options are exhausted, but in the event I can't find a replacement oil pan, is there any way of permanently repairing the one that I have?

If you have it removed you can try pin punching each side of the crack.
that will close it a little more, there are products like liquid steel .
they are a 2 part tube one is a hardener, the surface would need to be very clean but not sure how well it would stick.
How about a blown torch and a bit of 2% silver solder, even lead would work.

Thanks, threedogs. I have a couple of other places to check first before I have to resort to patching it. Best case scenario would be to find a replacement and just swap it out then put guards on the undercarriage for extra protection.

I would expect that if you have the pan off the car any competent welder would be able to run a weld along the crack for a permanent repair. No problem. Anyone with a Mig should be able to sort it for you. IMO you would only use liquid steel or other if you are repairing on the go and still on the car.

While the welder has it ask him to weld a second thicker skin on the underside for more protection. Easy job.

Agree with above.
If off the car, welding it is the way to go.

Yeah, for offroad purposes, we add diff guards and oil pan guards etc in here. Gives a peace of mind, when the bottom ends hit rocks etc, they don't crack or dent.
Mig welding it the way to go.
If it's mine, I would drain the oil, pull the pan out and clean it and weld it myself.
If you don't have a welder, just take it to a good mig welder in the area.
Then as Mudrunner suggested, adding a thick steel cover under the pan will give more peace of mind.
I wouldn't have a 4WD is Siberian winters without these extra precautions.

I myself am about to fabricate two diff guards and an oil pan guard for off road adventures.
You can purchase here it in Australia and have it shipped.
In my case, I prefer the fun of building it myself. :D

I have found the steel plate guards for diffs and complete undercarriage, so that is definitely on the mod list. Most of the 4x4 tuning places here offer them.

That's cool. I'm getting far east Siberia mixed up with Krasnoyarsk. :D
Those undercarriage guards come handy when you skid or sink or both at the same time in snow and end up hitting on rocks or ice.
I imagine 4WD vehicles are a big popular thing in Siberia, considering the heavy snowy winters you guys have there.

So, howz it going since the sparky appointment? No more dramas with sudden engine cut off or stalling?

No problems with the engine cutting off. It still has a hard time starting when hot. It takes several cranks to get it to fire. I will be taking it to a diesel specialist to do a compression test and test the injectors and look at the pump as well. That will be next week's project. Tomorrow I have the dealer lined up to replace the rear engine seal, kingpin bearings, drive belts, timing belt and a few other things.

If it's experiencing hard starts only when the engine is hot, I think it can't be lack of compression issue. Sounds more like fuel system or electric system issue, with more weight given to the latter cause. Nevertheless, it's a very good idea to get a compression test done asap.
If it hasn't been done for long time, it may due for injectors and pump rebuild.
