Delica Canada | Mitsubishi Van Club

So brought the ol Deli in to get the injectors cleaned and a look about. Sad news is that the block is cracked near the exhaust manifold.
Don't know when it happened, don't know how it happened. Though it would be nice to know so I don't do it again. Especially since I feel I have been driving her, albeit many miles, very conservatively. Either way looks like she needs some work.
I'm getting a quote from a shop but there is a chance I would try to tackle this myself (with help) in the winter months back in the PNW.
Right now I'm just trying to get an idea of the process and some do's and don'ts (I've replaced the head previous, so I have that as a reference.) Has anyone here had experience replacing the block and all the associated tasks?
It's an 89 exceed 4d56t for the record.

Its not as simple as replacing the block.If you plan to resuse the internal bits theres lots of measuring.

Your crankshaft journals will need to measured to get the right bearing thickness. .0010" over, .0020" over.
Your pistons might be worn around the skirts. Visual inspection.
Piston rings have to be sized to the bore for proper end gap.

You could just tear it down and have a shop do a short block rebuild for you. (Bottom end only). Block, pistons, con-rods, crank.

They would clean the block in caustic, paint it, put in new rings, bearings and give it back to you


Then you can put it back together when its done

Hey Joe,
I agree with Big Bird. Thats a huge job and considering the amounr of time and effort that goes into this job, its best to get it done the proper way. All parts he mentioned would need the correct sizing and replacements to suit the new (used) block.

If you just swap parts over into another block, you're setting yourself up for another engine job in the not too distant future.

Good luck!

Thanks for the replies guys. I like the idea of the short block rebuild, or if it's possible and not too terribly more expensive, to get a complete block package. All the internals seem a little much for me (hell the whole ordeal is probably too much for me so hopefully I can find a knowledgeable friend who can help me out
