1956-1974 Oil Filler Vent Tube End Cap 311115541 - OEM Number(s) (311-115-541)
This reproduction oil filler vent tube end cap is designed to seal the down-tube on your VW’s crankcase oil filler. When cracked, missing, or hardened, oil vapors can escape and create messy drips on the garage floor or in your engine bay. Without this cap, oil residue may also be drawn into the carburetor and burned, leading to smoky exhaust and carbon buildup. Installing a fresh end cap ensures your VW runs cleaner and more efficiently.
