Cylinder Heads and Gaskets in Brief
This category includes genuine Mercedes-Benz cylinder heads, head gaskets, valve covers, seals, and bolts for select engines. OEM parts match factory sealing surfaces and tolerances to help restore compression, prevent leaks, and support dependable engine operation.
The cylinder head seals the combustion chambers and houses valves, camshafts, and passages for coolant and oil. Common needs include valve cover gasket leaks, head gasket failure, and head replacement after overheating. Related parts include valves, camshafts and lifters, and rocker arms.

Why Genuine Head Components Help Prevent Repeat Leaks
Cylinder head parts must seal combustion pressure, coolant, and oil at the same time. Genuine Mercedes-Benz head gaskets, covers, and seals are designed for the engine's materials and clamping loads, helping prevent repeat leaks. Aftermarket gaskets may use different materials or thickness, which can affect compression or sealing. OEM parts are a dependable foundation for a repair that involves significant labor.
Finding the Right Cylinder Head Part
Enter your year, model, trim, and engine, then confirm the engine code with your VIN. V6, V8, and V12 engines may use different parts for each cylinder bank, so confirm left or right. Search by part number when available.
Engine Families and Bank-Specific Parts
Fitment varies by engine family, displacement, model year, and fuel type. Head bolts are often designed for one-time use, so check the service information and replace hardware as specified. Confirm fitment before ordering, and browse spark plugs and glow plugs and intake manifold parts for related service.

Mercedes-Benz Cylinder Head Questions
What are the signs of a blown head gasket?
Coolant loss without visible leaks, white exhaust smoke, overheating, or coolant in the oil can indicate head gasket failure.
Is a valve cover gasket leak serious?
It can drip oil onto hot exhaust parts and should be addressed. Replacement is usually far less involved than head work.
Are OEM head gaskets worth it?
OEM gaskets match the engine's materials and clamping loads, helping prevent repeat failures.
Can I replace a cylinder head myself?
Head replacement requires precise procedures and torque sequences. A qualified technician is recommended.
Should the cylinder head be checked after overheating?
Yes. Overheating can warp a head, so have a technician inspect it.
