Long Block Assembly
The cleaned and reconditioned components, as well as new parts, are reassembled into what is known as the "long block" assembly. The long block assembly is the heart of the engine and, when installed, connects to the other parts of the vehicle, such as the exhaust, fuel systems, and electrical systems.
Valves, valve seats, springs, and guides, along with crankshaft and connecting rods, are either remanufactured, resurfaced, or replaced. Cylinder heads are cleaned and resurfaced while cylinders are bored. Some of the new parts in a remanufactured engine include:
Piston and Pins | Piston Rings | Connecting Rod Bearings | Main and Camshaft Bearings | Pushrods | Timing Gear and Chain (Where Applicable) | Valve Lifters | Gasket and Seals | Freeze Plugs | Oil Pumps
Restored to Original Specifications
Once assembled, a remanufactured engine must meet factory specifications during oil pressure, compression, and vacuum testing. If your vehicle is in good shape but your engine isn't, replacing your engine with a remanufactured one is probably the only way you'll have "new car" performance. Not only is a quality remanufactured engine restored to original specifications, the end product can be better than a new engine of the same type.
