[Farmall] Stop leak oil additive

[Robert Schleyer]

I just rebuilt my 1950 cub motor last spring, completely tore it down and 
put new rings,bearings and new front and rear seals. There is a little bit 
of a system to doing this, buy the IH Service Manuel GSS-1411 and buy the 
DVD on E-Bay Engine Rebuild for Cub & Lo-Boy Tractors. These two items will 
help you. They show you a lot of the little things that make the job easier.
