I replaced the crankcase blow by filter and now oil is dripping out the blow by.
What did i do wrong, oil wasn't coming out before.

Double check the fit between the 2 parts of the down tube. They have to fit togather correctly or you will have a leak. Did you clean the oil return tube while it was out? Also, is the gasket still good? Chuck

I would guess if using new blue colored filter element, then it is too long and upsets the fit of the canister part to the body of the setup, common happening, trim shorter so canister locates in body before tightening.

The can has to sit on the rubber seal correctly or it will drip.Hard to see if its sitting right sometimes.Also as mentioned clean out return tube and trim filter if too long.Also the can end where bolt goes in can get distorted from overtightening over the years.Can be straightened from the inside with a little light tapping.
