I posted a thread last week regarding a oil leak coming from what I felt was the rear oil seal or around the rear crank journal. When i initially removed the valve cover i found 6-8 pipe cleaners stuffed down the rear oil hole in the block feeding ther rear journal. I received numerous helpful hints and I followed the advice of Dennis Piranio a well known Model A engine builder in Denton Tx. He advised it was probably due to wear in the Babbitt bearing and suggested I pull the rear crank journal remove a shim from one side, reinstall and torque down. turn the engine with the hand crank. Repeat the process one side at a time until I couldnt turn the engine. Then reinstall one shim and put it all back together. PROBLEM SOLVED!!!!!!!!!!!!!!!!!!! no leak larger than a nickel! the entire job took about three hours and cost about $20 for a pan gasket set!
BARGAIN!
