Thanks Rob......i will have to look up the records and see just how many miles i had on that lower end before rebuild.....what happened was the pinion shaft started flaking off the outer hardness , then that screwed up the pinion bearings and all that Chit went thru the motor taking stuff with it.......i checked the oil and seen that crap in the tank and pulled the motor out for re build....she only had to be bored .020 over...walls were scored and also new lower end crank shaft and bearings..and a few years later i added the S&S heads......she sure runns great and they all Love to Look at her.51elpanchop wrote:Awesome Panhead and story Mike. A friend of mine that rides a Shovel swears by the Marvel Mystery oil and like you he adds a little to his oil bag in the winter and a little in his gas. Any idea how many miles you got out of the Btm end before the rebuild?

I have a ole school mechanic that told me to add 4 oz's of Marvel to the oil change and yes i add some to my gas too........too much will foul plugs...in the gas and one ounce to 2 1/2 gals if the preferred mix.
The upper ring area is the driest part in the engine and marvel will lube that area quite well.
