Lean is mean but only in a quatermile. When an engine runs lean it runs hot, short term is frying your oil prematurly. Long term is you could burn a valve, melt a hole in the top of a piston, etc.
Have you ever seen the inside of an engine that has run too much nitrous? same thing it just takes longer to happen.

I understand heat is an issue. engine doen't run hot. Spark plugs are a light brown color. I read previous thread ponting at the AFM. Any suggestions?

Light brown/tan is good. Are you having other issues? Pinging/knocking?

How do you know it running lean? Hookup an AF meter?
