How to Tell a Long Block 22R From a Short Block

The 22R, 22RE and 22R-TE were without a doubt the most popular engines Toyota ever sold in America, reigning for two decades as the companys budget-priced workhorses. The rugged and dependable R-series all but created Toyotas image as we know it today, and continues as a favorite among off-roaders worldwide. The 97- to 112-horsepower carbureted 22R, 118-horsepower fuel-injected 22RE and 135-horsepower turbocharged 22R-TE werent powerhouses by anyones standards.

Instructions

1

Identify the engine block. The short block is the engines main sub-assembly, and is composed of the engine block, crankshaft, connecting rods and pistons.

2

Identify the cylinder head, which is bolted to the top of the engine block. Simply put, a "long block" is the short block plus the cylinder head. If the engine has a block, crankshaft, rods, pistons and a cylinder head, then its a long block. Most engine shops consider the valve assembly and cams as part of the long block, and will typically sell them that way unless otherwise specified. The camshaft/crankshaft sprockets and timing chain are typically sold as part of the long block assembly because the engine needs them to function.

3

Verify that it is, in fact, a 22R. Look on the engine block below the first brass freeze plug for the "22R" on the casting number plate. Other R-series blocks include the 18R, 16R, 10R, 9R, 8R, all the way down to 1R. Contrary to popular practice among Japanese automakers such as Mitsubishi, the engine designation indicated the engine generation rather than the displacement in liters. The 1R was first produced in 1953, the 2R in 1964 and so on.
