I have an aluminum oil pan with a few hairline fractures in it, just enough to leak some oil.

I am thinking of welding it and saving the money, would the best way be to heliarc it or would brazzing suffice?

Has anyone had experience with this?

 

squish some quiksteel in there and call it a day

 

Heliarc would be the best option if you have access to a machine. Otherwise brazing should work ok IMO

 

If you have to ask, you're better off buying a new one, or trying JB Weld or something similar.

Welding aluminum is tricky, and it will easily warp and you'll have a helluva time getting it to gasket/seal properly.

 

the problem is, a well used oil pan goes for $350+

 

Must not be for a Toyota huh?

If its that expensive, it would probably be a good idea to pay a professional welding shop to have it repaired.

 

probably because people need to replace them instead of repair them ...

 

Offtopic, but your 95 Avalon has a 1mzfe 3.0L V6 not 3.4L
