fixing a rusty sump.

[McWigglebum4th]

The wifes car has developed a pin hole in the sump due to rust

Easy fix drop the sump and TIG a nice patch over it

Until i had a closer look

The back bolts need the engine lifted out to get to as they right above the steering rack and sub frame

ARSE

So any nice chemical metals fixes that are pretty permanent

What car is it?

I think dropping the subframe is probably the easier option then taking the engine out.

I've seen a diff coated with body filler to stop it leaking, I wouldn't recommend it though.

The engine sits on the subframe

I used some silver plasticine type resin in a clear/red tube from halfords inside the sump of my old metro.

It had about 12 pinholes in the damn thing... But it was fixed forever after that

Rover produced a compound called Belzona (sp) years ago for their fwd gearboxes as these hung low and kept getting hit.
Cracking or holing them. Might be worth trying this.

Inside is the issue

If i could get inside i'd be sorted

Ah ha

A plan


Still want some sticky stuff

[Bill]

Would a self-tapper help hold the resin?

[Speed addicted]

Belzona is fairly effective stuff, we use it at work (offshore oil) to bodge up flanges and things that won't otherwise seal.

I fixed a cracked diff with chemical metal epoxy. It held up very very well indeed. Not structurally of course in case anyone thinks I did the impossible. There was a crack that leaked oil.

In your case I would suggest, since the area is flat, that you used a small patch of glassfibre matting too. This gives you a wide surface area of patch that is adhered well to the metal. Perhaps even 2 / 3 of layers of plasterboard tape if that is easier to source. Apply a layer of epoxy, then the tape or matting (while still wet, ie immediately) and again immediately, more epoxy to wet through whatever you use.

Obviously go down to bare metal, and absolutely degrease, using something like nitro thinners or other residue free degreaser.

You should be fine for quite a while, with any luck, for "ever".
