smoke coming from oil dip stick

51 cub, use with woods belly mower, used first time
this season today. Seem to have little puffs of smoke coming under top of oil dip stick. grey in color. Tractor runs ok, no loss of power.Is this something I need to send it in to have my local tractor repair shop look at??

Some blowby is normal, excessive could be a problem. If i remember right, there should be tube leading to the aircleaner to pull some of the blow by out of the crankcase. They sometimes plug up.

I wouldnt worry about it. My 154 does the same thing with less than 50 hours on a rebuilt engine. My 49 Cub does it too.
