If it's a stock engine case, it's not Aluminium. It's AS41 Magnesium alloy, (burns nicely when you get it hot enough).
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.alex1916v said:yeah? so your saying it cant be welded?
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 upLaurence Fletcher said:I tried one once, nearly burnt the garage down, (you would not believe the amount of white smoke it made).
