Toyota F engine

From Wikipedia, the free encyclopedia

The Toyota F-type petrol engine was introduced in 1951 along with the first real Land Cruiser. Based on the B-type truck engine, this 6-cylinder engine boasts the longest production history of any Toyota engine. This 3.9-litre engine was first fitted to the Land Cruiser 20-series, and many of these first F-type engines are still in service today.

The F engine is supposed to be based on the Chevy 225 I-6 "Cast Iron Wonder" and some of the bottom end of the engine is rumored to be interchangeable. The main differences between the F and the 2F are the 2F's larger bore, the F's 2 compression and 2 oil rings versus the 2F's 2 compression and single oil ring and the fact that the F had two oil paths--through the filter or through the engine compared to the 2F where all oil had to travel through the filter before the engine.
