This is a new very high quality and very correct crank case ventilator gasket. This is the little round gasket that fits on the side of the side valve inspection cover  where the ventilator housing is mounted to.  I have included pictures of both styles of ventilators  and there they fit. (they are for reference only and not part of the sale)  This gasket is used on both the 134L and 134F four cylinder motors.   This fits the MB, GPW, CJ2A, CJ3A, Cj3B, M38, and M38A1.   This sale is for the gasket only.   QTM Parts.
