need help with my 83 shovel

I picked up a 83 flh and it runs great except that it pumps oil out of the breather tube. I checked the compression and it is running @ 95 to 100 psi, so I don't think that it is blow by. A friend said that something in the heads ,some rubber valve might be bad. I can't find it in my shop manual. Can some one tell me if this might be the problem. I found them in the evo but I can't find it in the shovel. Thanks, harley 49266

May be its the ball check valve and screen located in the front of the oil pump on the right side case.A stuck ball will alow the oil to backflow into the cases and when you fire it up the oil will pumped through the vent line to the
breather.

check the screen in the oil pump

There is no rubber valve in the heads on a shovel bro, thats an evo thing.
Like Bernie said, check the tappet screen in the oil pump and that check ball, it might be gummed up, or both might be. I clean my tappet screen everytime I change the oil just for good measure.
hope this helps
ride safe

Thanks for the help

Thank you for the good advice, when it stops snowing I will try the fix that you talked about. again, thanks, harley49266
