Connecting Hoses & Pipes

All crankcase ventilation systems use connecting hoses and pipes to carry crankcase gases, engine vacuum and/or outside air. Hoses and pipes should be checked for clogging and leaks and replaced as necessary.

NOTE: Following figures are representative of typical crankcase ventilation systems for various manufacturers.
