Re: What is a plenum and what are poppet valves?

A poppet valve is what's used for the cylinders - the intake and exhaust valves are poppet valves. A leaky intake valve can definitely leak into the plenum, but usually intake valves don't leak or get burned under normal use.
the poppet valve they are talking about is the injector its self. if it was the intake or exhaust valve they would just call it the intake or exhaust valve. what I was getting at was he needs new injectors to fix the problem
