From 1986 to 1992, the company produced the 3.0-liter 24-valve Toyota 7M-GE engine, which was fitted to popular Japanese vehicles like the Supra, Chaser, Crown, and Mark II. A unique configuration of valves at a 50-degree angle set this power unit apart.
The 5M-EU, 5M-GE, and 7M-GTE engines are also part of the M family.
The engine was mounted on:
- Toyota Chaser 4 (X80) in 1989 – 1992;
- Toyota Crown 8 (S130) in 1987 – 1991;
- Toyota Mark II 6 (X80) in 1988 – 1992;
- Toyota Supra 3 (A70) in 1986 – 1992.

Disadvantages of the Toyota 7M-GE engine
A cylinder head gasket failure near the sixth cylinder is the most well-known engine issue;
Owners frequently overstretch and break the cylinder head bolts;
Additionally, the ignition system frequently fails here, and the idle valve sticks;
One of the engine’s weaknesses is the oil pump, which performs poorly;
There are no hydraulic lifters, and the valves must be adjusted every 100,000 kilometers.
