Repairing a rusted oil pan

[radek at istar.ca]

Thanks guys for your suggestions.

I don't think there is enough metal in that pan to hold a magnet or a screw.  It's all
rust.  I guess I have 
no choice but to "lower" the subframe.  Somehow, I have a feeling it's not going to go
smoothly.  Those 
subframe mounts have been exposed to the same salt as the oil pan.  I was kinda hoping
that there 
would be some miracle substance out there that would stick to the oily rust on the outside
of the pan 
and seal it for a couple more years.  Oh, well, I'll call the dealer tomorrow for the
price on a new pan.
Thanks again.
