I have been having to clean up the area around my front sprocket almost weekly. At first I just figured it was all the grease from the chain. However, the last cleaning I did I cleaned the chain up really good. When I went to clean it up this morning, there seemed to be oil pooling in the bolt hole dimples.
I wiped up the access and took some pictures of my engine casing now tinted brown. Could I have an oil leak somewhere around here? Is there anyway, or any product, that can clean the casing without ruining it?
The first image has a vivid effect on it so you can see where the oil/grease has been collecting on the engine staining it. The second one is more of what it looks like to the naked eye.
