Sump oil leak

Hi
I've got a slight oil leak from the sump, just the odd drop of oil on the garage floor. It's actually been there for a couple of years and I've been lazy about fixing it. Before I get the spanners out just wonder if anyone had removed the sump and new of any potential pitfalls?
Thanks

You will really need a new sump. They are made of unobtanium* :ohmy: with a high iron content, so they rust and go porous.

If you are lucky, with the sump off, you will see a couple of marks on the inside, then clean the oil with powerful solvents, derust the outside, and either braze up the holes, or simply coat the outside in leak-fix. (I'd go over the braze with leak-fix anyway)

There is no gasket, just RTV.

AFAIK, you can remove the sump in situ, but the axle might need to drop down a bit.

Suzuki are very good at sealing joints**, so it wont leak there, but on the single cam, there is a known seal failure at the back of the cam, check it isn't this.


*You try getting a second hand one that isn't as rusty as your own.

**the lack of oil everywhere causes terrific rust problems, that you don't see on a LandRover

UNOBTANIUM ??

Like Guinness...pure genius

So not the easy half hour job on a Sunday afternoon I was hoping for then.

If you clean the sump in situ(difficult I know especially the right hand side unless you have small hands(baby size)) and can identify the porous patch then the two pack epoxy putty that sets rock hard is often a good fix. We used to use it on the aircraft as a dent filler to smooth the airflow until a down time could be scheduled for a replacement/repair. We had a B757 with a dent on the leading edge of a horizontal tail stabiliser flying about for years no problems.We use to call it hermetal but there are a number of brands on the market. The one I have now is called Milliput and consists of a yellow and grey length of putty which you mix in equal lengths (just cut the amount of each with a sharp craft knife) and mix together until the colours have combined into an even mix. It is easy to use and can be sanded, painted or whatever once its hardened.

I'm pretty sure its the gasket that is leaking. Before I start I'll have a careful check round for rust patches.
