Ensure a reliable, leak-free seal between the left cylinder head and engine block on your Mercedes Sprinter with this Left Head Gasket – part #6420165120ELR. Designed specifically for the OM642 3.0 L V6 diesel engine, this gasket seals combustion chambers, coolant passages, and oil passages — helping maintain compression, prevent fluid cross-contamination, and avoid costly overheating or engine damage. This left-side gasket is a critical component in top-end engine service, especially during head gasket replacement, cylinder head removal, or engine rebuilds.

✔ Ideal for Repairs & Rebuilds
