In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...
The location has been the primary source of engine block and cylinder heads for all of GM's engines, to include Oldsmobile, Pontiac, Cadillac, Chevrolet, Buick and GMC for most of the 20th century. The address is 1629 N Washington Ave. Saginaw, MI 48601, and is located on the Saginaw River .
The base of a reciprocating internal combustion engine is the engine block, which is typically made of cast iron (due to its good wear resistance and low cost) [22] or aluminum. In the latter case, the cylinder liners are made of cast iron or steel, [23] or a coating such as nikasil or alusil. The engine block contains the cylinders.
Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst or pop out, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.

A crossflow T-head sidevalve engine The usual L-head arrangement Pop-up pistons may be used to increase compression ratio Flathead with Ricardo's turbulent head. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve ...
The engine manufacturing process started when cylinder blocks arrived from one of the supplying foundries, one of which was Morris's own. After being inspected, pickled, washed and dried, the blocks were placed on a hand-transfer machining line that carried out 53 operations in turn.
While this process is simple, the dimensional accuracy is low. [3] Another type of binder process is called the hot-box process, which uses a thermoset and catalyst for a binder. The sand with the binder is packed into a core box that is heated to approximately 230 °C (446 °F) (which is where the name originated from).
An engine block with aluminum and magnesium die castings. Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.
