S&S V124 Front Head/Cylinder Seeping.

(1/1)

ltank:
My S&S V124 front head/ cylinder gasket is starting to leak. It looks like it at the oil return from the head to cylinder. Is this a common problem? I always warm the motor by running it about 3 minutes and Ride slowly for 2 miles on dirt road before accelerating.
  I have a RSR Air/Fuel Ratio meter and it shows good. The Sensor is in the front pipe. Any Advice?
 Is it something did wrong?

johnsachs:
It could be a stud that's pulling itself out of the case. Are you sure it's the head gasket weeping, and not a bad exhaust valve guide seal, or loose guide letting oil exit the exhaust port between the pipe and port ? You can put an air fitting in your spark plug hole, pressurize the cylinder after removing the pushrods. That should point you to the problem quickly.

ltank:
Ok thank you.

Bike isn't using excessive amount of oil. Maybe a cup of oil every 3500 miles. There isn't any oil in the exhaust pipe header. If it was a guide or a seal etc wouldn't it show up on the spark plug? Spark plug looks fine
