Re: Oil leak
I checked both those areas, as well as others, very carefully. All dry. I could see evidence of oil on the bottom of the header flange for cylinders 2 and 4. Top of the header flange is dry. With a good light, I can see where the oil sheen starts. I thought maybe the timing chain tensioner cover, but that was dry also. Only leaks when engine is running. May also explain why I need to add coolant every few hundred miles.
The engine is a Haibeck 415.
