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.

Engine Rebuild Menu:
Teardown and Inspection, Hot tank and clean, Magnuflux for cracks or needed repairs. Replace any missing or broken parts.
Machine Service- Hone engine block, grind and polish the crank and cam, Valve job on the cylinder head.
Engine Rebuild Kit- New rings, engine bearings, gaskets, freeze plugs, and timing set.
Clean, Paint, and Assemble.

We’re ready to dive in and teardown and hot tank all the parts, scrub and clean so we can inspect for any cracks or repairs.

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.

    Hi, we have a 3g81 from a 1989 mitsubishi minicab. just got the block hot tanked and the deck resurfaced, but the local machine shop was unable to hone/bore the cylinders because it was too small for their equipment. got one cylinder that as deeper grooves in it from some wear or damage, no cracks in the cylinders but it may need to be bored out further or possibly resleeved. how much to get 1 cylinder resleeved and then all 3 cylinders machine in bore size? it might get away just boring it out further, then getting the other cylinders bored out to match as well.

    Do you sell a complete engine rebuild kit for a 3G81? Out of a 89’ U15T? Also a price for a rebuilt engine? Also interested in a manual for the engine ie: what are all these damn hoses? What do I really need and what can I get rid of? Thank you

      Do you guys sell rebuilt 3g8s? I have 2 and I’m not sure if they can be salvaged. Was given and minicab and it has a motor on it with the heads in the floor board and an extra motor in the back for parts I’m assuming.

    Can I also get a price for a 3G81? Also by any chance you have carburetors for this motor? Used carburetor is fine.

    How much for a rebuilt 3g81 and how much to restore and rebuild the same engine? I have one that’s in desperate need of attention! Also can you supply other OEM parts like fuel pump, leaf springs, etc?

      Thanwin,
      Yes, the clearance can be adjusted. I believe it is 8 intake and 12 exhaust. Be careful or you might break the rocker arms, those are hard to come by.
      Let me know if you need more information.
      Thanks

      Gail,
      Thank you for contacting us for information on your 3G81.
      I know, information is incredibly hard to find for the 3G81 engine.

      We rebuild quite a few of these engines, although I never have time to put up more photos of others we have rebuilt.

      I do have the information for you, I’m sure you will be quite pleased.
      I cannot attach files here, so I am sending you a PDF of the Valve Clearance and the Timing marks via email.

      Let me know how it turns out!
      Regards,
      Lucinda

      Alex,
      Thanks for contacting us regarding your 3G83.
      A crank grind runs $85.00, if it is salvageable. You need to measure it first and let me know what size it is. If it is more than .20 over, bearings may not be available.

      Also compare the rods, you might need a new one. Measure the inside bore of the rod.
      New rods run about $110.00 each.
      Shipping is Not included in any quoted pricing.

      If you have any questions, call the shop and ask for Joe 818 767-6603.
      Thanks,
      Lucinda

      Chris,
      Thanks for inquiring on a solution for your 3G81 engine problems.
      The smoke can be from a variety of issues, the valves, guides, head problem.
      I will email you directly estimates on a valve job for your 3G81 and an estimate to remanufacture your 3G81.

      Thanks
