reeto, he's a strage one, basically the two top mountings for my engine support bar on my 68bay have kinda sheerd off, there were previoulsly heli coiled, and now are snapped off, my only thought to fix this problem os to remved the engine and aluminum weld the case, ie just blob it up in that area, grind it flat, re drill and tapp the holes, all of this i can do quite easily, but my only question is would you ever weld a case without splitting it and draining the oil etc,
as i dont know how thick these cases are in this area im not too sure what can and cant be done, im hoping to remove it soon ish to change a flywheel oil seal and to renew my engien bay seals etc, so any info would be good, dont worry i can weld aluminum, just wnna be sure its ok to do this....

If it's a stock engine case, it's not Aluminium. It's AS41 Magnesium alloy, (burns nicely when you get it hot enough).

yeah? so your saying it cant be welded?
No, they can be welded, but it's not your ordinary aluminium welding. I tried one once, nearly burnt the garage down, (you would not believe the amount of white smoke it made). You need to check with one of the engine tuning suppliers, they get cases welded to reinforce them in critical places, I'm not sure of the actual process they use, but I do think you'll need to drain the oil.

i remember chemistry at school and sticking a small strip of magnesium in a bunsen burner - bright white light and lots of smoke - must be some light show when a case goes up
