Re: rear main leaking
The rear "seal" is just an oil slinger. Some oil gets by and that is why Henry made the drain hole with the big cotter pin to keep the hole open. Make sure you are not overfilling the crankcase. 4 quarts. 4 1/2 if you have a filter. John

Re: rear main leaking
Well I just learned something else.....so my 38' 21 stud flathead only holds 4 quarts! I just put in 5 quarts 3 days ago.

Re: rear main leaking
Well, I hope I haven't started the oil capacity thing again. If I don't change the filter, 4 qts brings our 46 to the full line on the dipstick. John

Re: rear main leaking
A common place modification on the prewar models was to make a little oblong tray from a suitable size tin or tin lid, and mount it on a piece of strap steel held on the engine by a bellhousing bolt. If you put a wing nut on the bolt holding the lid to the strap, you can empty it easily once a month.
I remember seeing this mod in Popular Mechanics back in the 50s or early 60s. |
