Oiwa Garage Tech Note

"If the old cap seal is hard and shiny, the crankcase pressure is pushing past it - a fresh cap seals the filler and keeps oil off the engine."

Frequently Asked Questions

How do I know the filler cap seal is bad?

If the cap seal is hard and shiny and you see oil weeping at the filler neck, crankcase pressure is pushing past it. A fresh cap with a good seal closes the neck cleanly.

Does a loose filler cap affect running?

A cap that does not seal lets the crankcase breathe wrong and can weep oil, so make sure it seats and clicks home.
