The list above is for reference. It is crucial to verify the engine type (e.g., Perkins 403C/403D), thickness (1.3mm), and bore (78mm).
A head gasket is the centerpiece of a top-end engine rebuild. When replacing it, it is absolutely essential to also replace the cylinder head bolts with a new set. We also recommend inspecting the valve cover gasket, valve stem seals, and having the cylinder head resurfaced.
A failed ("blown") head gasket leads to serious engine failure. It can cause oil and coolant to mix (creating "milkshake" sludge), combustion gases to enter the cooling system (risking a burst radiator or hoses), or loss of compression. Ignoring these symptoms will lead to engine seizure or a cracked head/block.
The 02/630575 head gasket is the most critical seal in an engine. It is a thin, multi-layer plate clamped between the engine block and the cylinder head. Its job is to hermetically seal the combustion chambers (to maintain compression) and to separate the pressurized oil channels and coolant passages that flow between the block and head.
