Produced in Japan between 1979 and 1989, the 2.8-liter 12-valve Toyota 5M-EU engine was installed simultaneously on several generations of popular models, including the Supra, Cressida, and Crown. This power unit is referred to as the 5M-E in the Australian and European markets.
The 5M-GE, 7M-GE, and 7M-GTE engines are also part of the M family.
The engine was mounted on:
- Toyota Cressida 2 (X60) in 1980 – 1984; Cressida 3 (X70) in 1984 – 1988;
- Toyota Crown 6 (S110) in 1979 – 1983; Crown 7 (S120) in 1983 – 1987; Crown 8 (S130) in 1987 – 1989;
- Toyota Supra 1 (A40) in 1979 – 1981; Supra A50 in 1979 – 1981; Supra 2 (A60) in 1981 – 1985.

Disadvantages of the 5M-EU engine
Cylinder head gasket failure is a well-known issue with power units in this series;
Owners frequently overtighten the head bolts in an attempt to stop oil leaks;
Here, contamination of the throttle or idle valve is typically the cause of floating speed;
The ignition system’s erratic behavior is typically linked to the remaining engine failures;
The valves need to be adjusted on a regular basis because there are no hydraulic lifters.
