IIRC from looking at my Dad's 9N the "oil pan" remains a structural
member of the frame even after the block is pulled out of the tractor.
I know that our neighborhood mechanic pulled the engine out of my Dad's
and rebuilt it a few years ago, so it can't be impossible.
I suppose the really, really right way to go would be to strip it all the
way down, build up the spot with welding or brazing, then machine it down
nice and flat. On the way you can blueprint the engine.
You can get V-8 conversion kits for those, you know: http://
www.staufferv8.com/v8conversion.html. _That_ will fix it!

When I was young, a friend got too many wiskey tickets. So, he did this
conversion (you don't need a licence to drive a tractor) People really
looked at him funny when he passed them on the highway
When I got the manifold gaskets today, I asked the old fella in there what
he used for this problem. JB-weld was the answer. So, my JB-weld job is
drying right now.

Please log in for more thread options The red high temp RTV silicone will last a very long time on exhaust
gaskets, especially on your block which will limit the max temp pretty well.

Clean it VERY well and use JB Weld The standard stuff NOT the fast
setting. OR clean it very well, Hit it with some acid flux and braze it,
then file it flat. OR weld it up with some nickel rod and file that
flat. All of those can easily be done with the block installed. Stick
some rags in the ports prior to doing the repairs.
