20850048 — Cylinder Head Gasket 20850048 For Volvo Penta Engine Tad650Ve Tad660Ve

This cylinder head gasket is a critical sealing component situated between the engine block and the cylinder head, responsible for sealing the combustion chambers, oil passages, and coolant passages. It ensures proper compression and prevents the mixing of oil and coolant. A blown head gasket can lead to coolant entering the combustion chamber (causing white smoke), oil entering the coolant (causing milky oil), or combustion gases escaping into the coolant system (causing overheating).

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A blown cylinder head gasket may initially manifest as white smoke from the exhaust (coolant burning) or a milky appearance in the engine oil. You might also observe coolant loss without visible external leaks or experience engine overheating. If left unaddressed, these symptoms can lead to severe internal engine damage, including hydraulic lock or bearing failure due to coolant contamination.

Installation Tip

Ensure both the cylinder head and engine block surfaces are perfectly clean and flat before installing the new gasket. Always follow the manufacturer's specified torque sequence and values for tightening the cylinder head bolts.

Service Note

When replacing the cylinder head gasket, it is critical to check the cylinder head for flatness and replace the cylinder head bolts if they are torque-to-yield type.
