My Lady identified as a Harley this morning. She has an oil leak from the left side of the timing belt cover or from the cylinder head gasket. It's hard to tell until I really clean it up. The leak is only a drop every 10 minutes and only if the engine is running or has just been running. I doubt if it is the cylinder head gasket.
All the bolts on the timing cover are tight.
The timing belt cover hasn't been off in about 3 years. Looking at the parts drawing, the gasket looks like it is split on the left end. It doesn't look continuous like an O-ring. I don't remember. Can anyone verify that for me?

You are correct. Anything could happen, but Valkyrie oil leaks are usually the shifter shaft seal.

Thank you gentlemen. My first thought was the shifter seal, but nothing is that easy for me. This leak is at the front left side of the engine.

the last time valve covers were off, the camshaft bearing supports need sealant put in the corners before installing covers. only place in that area that could easily leak oil.

It could be the oil seal #22 on the end of the cam. Not a difficult job, just takes time and patience. There's also a small gasket behind the timing belt covers on each side...#6 for the left side. It goes between the cover and the cylinder head. I've had to change both in the past. https://www.servicehonda.com/oemparts/a/hon/506cb666f870023420a41822/cylinder-head |

The number for the small gasket is actually #7. Regardless of the minor detail, that is where the leak is coming from. Thanks for the tip. Parts on order. |

I'm talking about the small paper type gasket that goes behind the timing belt covers on each side...between that cover and the cylinder head. Couldn't really see a need for it but rather than order one a while back while working on the Wing engine, I simply cut one out of some gasket material. If the leak is coming from the area of #7, then your leak is internal and coming from somewhere else and just showing up in the area of #7. |

Fortunately I have experience forming paper gaskets. |
