Sump Weld

[Guest old_timbo]

When I cracked mine, I took it of welded inside and out, filled it with water and left it for 3 days. No leaks. One heat cycle and some vibration back on the engine and it started weeping again Just putting up with it for now.

Use paraffin then, it's much more likely to find a leak as it creeps better (reversed miniscus I believe)

I used diesel when mine leaked. Took it to an ali welder 3 times and it still didn't cure it. In the end I used steel putty inside and out, now cured, but I seem to have a gearbox leak now! Me thinks it could be between the bell housing and the box it self, not having a gasket fitted cos I forgot to fit it until everything was back in, D'oh!!!!

Thanks guys.

 

24 hours and no leaks. Will fit it back on the car Sunday and run up to temperature with a things crossed.

 

Rolling road booked for Thursday so need to get it all back together.

 

Cheers

I take it that it wasn't one of mine then.

 

As Florin suggests, use paraffin for leak checking.

 

Reading between the lines, I suggest if you are worried about mixing oil and water, then it's because the edges being welded aren't clean enough in the first place and you could be pulling impurities into the weld.

 

I know some people on here use Mig but I would recommend always Tig welding.
