Mitsubishi 3G81 Engine Rebuild
This is a Mitsubishi Minicab 3G81 6V SOHC 3-cylinder 550cc engine in for a complete rebuild.
Everything about this engine is mini!
We get quite a few of these in for rebuilds. They come out of smaller work trucks that usually don’t drive on the road. Mostly imported from Japan. They get the same treatment as the big guys.

3G81 Machine Services
All the parts are good, so we move on to resurfacing the cylinder head, polishing the crank , starting the engine block work and then give everything a coat of paint.
Cylinder head gets a valve job: grind/ cut valve seats (3 angle), resurface, clean and assemble. New valves installed to replace some bent valves, the good valves were ground to proper specs to seat nicely.
We’re ready for assembly. Short block parts assembled, then the long block is put together. I say long block, but this Minicab engine is tiny in comparison to our usual Fords, Chevy’s and GMC motors.
3G81 Minicab engine rebuild kit included: new piston rings, engine bearings, gaskets, seals, timing belt and tensioner.
Behold the remanufactured Mitsubishi Minicab 3G81 3 cylinder engine. It’s ready for pick up.
