Oil Leak

Energy One

Have a 2010 Mastiff EFI 117 S&S motor.
Guess I didnt give it the 3 min warm up before getting on the throttle. Developed a oil leak from the Top of the rear cylynder, guessing the Valve cover gasket has blown. Tried tightening the 6 bolts, primarily the left rear bolt and only slowed the leak down but it still drips just sitting in the garage.
Anyone have any knowldege what Im looking at for repairs? Does the engine have to be pulled to change the gasket? Looks like a couple of the bolts are right under the frame.:bang:
Any help would be appreciated.

No, you don´t need to touch anything else, just take the gas tank out and pull the covers. :up:

I am not sure on the Mastiff but on the K9 I had to shorten an Allen key so it would fit between the rear/left bolt and the frame. (TP Boxes)

:cheers:

The covers are sealed with an O ring type material. You probably need to replace the rocker box gaskets. Those are the ones that always develop leaks on my Pit.
