Fibre washer

A fibre sealing washer used with the oil pump/release valve and manifold fittings on the engine's oil system.

PN · GS254
Superseded by 70-8754.

GS254 is a fibre washer that shows up in the oil pump and release valve area on the catalog side of the engine, appearing across manifold and tappet figures as well. It's a small sealing piece used where the oil pressure release valve or related fitting seats against the case, keeping the joint sealed without crushing the surface the way a metal washer might.
