R pony motor leak

if I remember the pony oil pan is the top of the tractor crankcase, so would guess the gasket is bad or maybe the engine hold down bolts are loose. John cummins
 
When you crank it up, is the oil coming from under the bell housing, towards the back of the pony engine?

If so, the rear main bushing and seal on the crankshaft needs replaced. Sometimes the crank journal is scored bad enough that a regrind is needed, or even welded back up and turned to make it right.
 
Kent there is NOT an oil pan on an R pony. The crankcase is open, & seals to the tractors main case. All that's wrong is the gasket blows out here because it's rotten cork. It's 4 bolts lift pony clean reseal, done.
 
Gtx thanks for the information. My R has been leaking in this same place ever since I bought it in 1990. I keep washing it off instead of fixing it because I thought it would be a big job. Looks like I have another winter project for the shop now. JIm
