Description

SIERRA GM 5.0L / 5.7L Valve Cover Gasket – 18-2845

Sierra 18-2845 is a Valve cover gasket engineered for the specified marine application. GM 305 / 350 CID (5.0L / 5.7L) marine V8 engines used by MerCruiser, OMC, Crusader and related marinized-engine families matching the listed OEM references.

• Valve-cover gasket for GM small-block 305/350 CID marine V8 engines.
• Fits 5.0L and 5.7L GM-based marine applications where the listed OEM number is specified.
• Cross-references MerCruiser 27-11999 / 27-34043 / 27-52202, OMC 912965, Crusader 91351 and related numbers.
• Seals the rocker/valve-cover flange to control crankcase oil leakage.
• Check valve-cover flange straightness and fastener torque; over-tightening can distort the cover and cause repeat leaks.

Fitment for marine engine and drive service parts can vary by model, serial number, gearcase, cooling configuration and prior component supersessions. Compare the original OEM number and physical configuration before installation, and renew related seals, locking hardware or adjacent wear items when their condition requires it.
