1988-1991 C4 Crankcase PCV Vent Hose 10055872 - OEM Number(s) (10055872)

Restore proper PCV system function on your 1988-1991 C4 Corvette L98 engine with this molded rubber crankcase PCV vent hose, the correct formed replacement that connects the PCV valve to the throttle body on the right hand side of the engine.

The PCV vent hose on a 1988-1991 C4 Corvette L98 engine carries crankcase vapors from the PCV valve to the throttle body as part of the emissions and crankcase ventilation system. After decades of underhood heat cycles, the original molded rubber hose hardens, cracks, or collapses, leading to vacuum leaks, idle issues, and a PCV system that no longer functions the way it should.

This formed molded rubber replacement restores the correct shape and routing on the right hand side of the engine. We always recommend replacing the PCV valve at the same time if your hose is missing or damaged — a clean PCV system depends on both parts being right.

Because Details Matter: The PCV system is one of those quiet underhood circuits that only gets noticed when it stops working — and on an L98 Corvette, a collapsed or cracked PCV hose shows up as rough idle, vacuum leak codes, and a crankcase that no longer breathes correctly. The right molded rubber replacement holds its shape, seals correctly, and restores the PCV path the L98 was engineered with. Pair it with a fresh PCV valve and the system runs the way it should.
