damaged sump

mrchips283

I recently damaged the alloy sump on my merc 190E

The car is old but I love it and need the sump repairing, I drove down a dirt track and now have a crack in the front of the sump.

I have been quoted £700 at garage to get it fixed, does anyone have any ideas?

TIA

thats a bit steep, get a second hand one, would thought it be no more then £50, gasket set about £40 plus bolts, drain the oil and replace your self.
try https://www.findapart.com for a new sump

You could also try having it welded.

Replacing the sump is difficult as you need to remove the engine, and you cannot weld the alloy as the heat from the welding process can set fire to the residual oil that is in the engine.

I would suggest trying Here


You will have to drain every last bit of engine oil out of the sump then raise it up on ramps and use the easyweld kit to repair the hole. The easyweld gets no where near as hot as normal welding and so it is a lot safer for such applications, the heat will also be localised to that area of the sump.

I would suggest practicing first on some scrap alluminium, only attemt to fix the sump yourself if you are reasonably competent, if you are the type of person that can have an accident in an empty room then take it to the garage!

If all else fails you could try this epoxy putty, it's widely used in industry for repairs on casting where a weld repair is not possible.

You can buy a similar, cheaper version at plumbers merchants as epoxy putty sticks for general leak repairs, and it is usually very effective.
The only problem is when you do a repair like this there is always the thought in the back of your mind “when is it going to fall off”.
But if you’re between a rock and a hard place what have you to lose!

I think epoxy putty is the answer here but it needs to be completely clean. TiG welding is another possibility but it's a skilled job and won't be cheap. There's a slight possibility of the oil igniting but I personally think it's unlikely. The gas shield in TiG welding cools the weld and oil needs quite a lot of sustained heat, and a supply of oxygen, to ignite.
