Deuce oil leak Need HELP

[052]

I just recently purchased a Deuce and have an oil leak where the engine and tranny bolt together. I have had the rear main seal replaced, but the leak comes back, usually worse than before. The mechanic I have working on it has tried fixing it twice, but we can't stop the leak. Any suggestions ???

Thanks in advance

Check your crankcase vent and make sure it is not plugged. High crankcase pressure will cause the seal to leak.

Thanks for the reply. If there is a clog will this show on the oil pressure gauge as well? The oil pressure has been steady since I picked up the Deuce.

When I did the clutch on my truck the rear main was dry, but there seemed to be oil comming from the starter area. The back of the engine was dry, but there was oil on the right side of the bell housing. We cleaned it up and put it back together. If anyone has any ideas let me know. I will check the crankcase vent tomorrow when I put on the spin ons on, Thanks John.

No, no effect on th oil pressure. Are you sure it is engine oil? Also remember, oil leaks start high and drip or run down. Check the head gasket, valve cover and tappit cover. Maybe it is external.
