Cracked bellhousing - to weld or not to weld

Well i knew i should have stayed in bed !

I spent the morning levelling the engine in the car and tweeking the gearbox cross member to make everything dead level and straight. Job done.

Removed the engine and gearbox from the car and as i lowered it to the deck i heard a 'ping'

i knew what it meant,bugger. After separating the box from the engine i have found 2 cracks about 40mm long.

I could buy a new bellhousing from the states, but i could also Tig weld the 2 cracks.

Has anybody on here had a go at tig welding alloy ? I have a few years back but i'm not 100% on its final strength on a part like this? Should i give it a go ? I am in two minds

You could also just drill a hole at the crack end to stop it going any further about an 1/8th dia should do the trick.

It's what we did in the aero engine industry on the tin ware etc.

Weld it, if it all goes wrong then get a new one.

Argggh

Not to weld, just been cleaning up the cracks and found a third. Thats three to many for this many horses !.

Been on ebay US and found a couple of bellhousings pretty cheap, just trying to do a deal to get them shipped.
