When I got home, I left the block in the car but pulled out all the boxes of parts, and did a quick inventory of what we got for a handful of hundies...

1990 Dodge w200 auto pickup motor with a supposed 190k miles. #1 piston is melted around the top ring land, and the bore is scored. Research says it was probably a failed injector. The rest of the pistons/bores looked ok on a quick look. Seller is a young diesel mechanic said his shop foreman said have a liner put in there, new piston, new rings, glaze bust it and it will prob do another 200k.
My research says thatís a common approach.

Not my style, so I am thinking a 20 thou overbore, new pistons, bearings and do it right. Rotating assembly spins easily by hand. I will see how the bottom end is once I get it on a stand.
Engine has had the famous killer dowel pin come out an break the front timing case, so will need to find a replacement. Gears look good, with no chips or obvious issues.

Cylinder head is complete with no obvious cracks or valve issues. Injectors are still installed.
Going thru all the boxes...
Turbo is clean with just a little play. Lift pump, and Injection pump is there, and looks rebuilt. Complete intake system inc original air filter housing, pipework, intake heater, crossover pipe, and exhaust manifold and turbo down pipe. Timing gears, crankshaft damper, front cover, push rod cover, starter motor, ac compressor, alternator, ps pump, vacuum pump, oil filler, oil filter housing, and dipstick. Water-pump, radiator hoses, fan, and fan clutch etc.
in short, looks like I have everything except the radiator and intercooler if it had one.

IIRC with the Cummins you have one rebore and that's it, as opposed to the Isuzu that can be re-sleeved easily, and over and over; no machining to the sleeve at all.

I don't think first gens had intercoolers until 1994.

Yeah, a dripping injector can do amazing damage. If you hear a louder than usual knocking noise, shut her down and start pulling injectors. Thats why it pays to run diesel conditioner, ESPECIALLY now days with ultra low sulphur diesel. There is not as much lubricity with modern diesel fuel, which the fuel pump and injectors require on these older diesels. I usually am pretty generous with the conditioner.

A very good article:

http://www.sacea.org.za/docs/sait%20...s_2_shrunk.pdf

Are you planning on running an Allison behind her?

If you have any questions at all, like I said my neighbour is an expat Brit that knows pretty well all there is to know about 12V's. I'll take any questions you have to him.

Cheers
Tony

Thanks for the input Tony.

I'm green on these Cummins thingies, so I think I posted all the info your buddy might need....
1/ I am finding Std, 20, and 40 tho oversize pistons. Note that some of what looks like scoring, especially around the top of the bore is actually melted piston deposits!
2/ Not expecting anything too serious on the bottom end, but 10, 20, 30 and 40 undersized are available.
3/ VE pump models are a little weaker that P-Pump, but VE can be converted to P, if you are dedicated... I doubt I would. Adding the modified fueling pin, and 3200rpm gov spring makes sense.
4/ Std Turbo is good for 300hp, which is more than the VE pump can do I am reading... 250hp/500tq would make it better than the 454!
5/ I am not sure about the Intercooler... I read its possible to add one to the earlier models.

Get your buddies opinion and post it or PM me!

You can add an intercooler to any, it's just the plumbing that matters. Make sure to go to a cummins power shop with your engine serial number to get your controlled parts list number, and indexed parts list. Also, since all parts come from cummins, recommend cummins power club, $20/year and 10% off on parts and labor. I like it for the parts savings. Did you get the transmission from the dodge too?

Good info.
Like I said, once I know what I have and how Iím gonna build it out, it will become an underbench back burner project. I can chip away at it as time and budget allow. I cannot believe how much the short block weighs! Iím gonna have to build a special stand for it. I think itís probably around 700lb.
The seller had the Trans from the motor but he said it was a non lock up auto so I didnít look at it. I think it was the A518 which is an OD unit and I think it had was a 4wd, because I noticed it seemed short, but I was focused on the engine. I have a 4L80e under my bench, but Iím not thinking about that for now.

The Allison md3060 transmission is a nice pairing. 6 speeds, some have an oil sensor internal, that allow you to check the level at the panel. No replacement for dip stick, but handy if diagnosing an issue on the road.

The 5.9L 12v is speced at 1,100 lbs dry.

Do you happen to have large numbers on the block of 53?

The Range Rover and itís air-suspension was superb. I folded the seats down, dropped the suspension to the bump stops, and reversed into the cherry picker. Got everything secured and strapped down, punched the button and up she went to normal ride height. The dry weight cummins quote is 1100lb.... and Iím not gonna argue with under .50c/lb!
I put 10psi extra in the tires and drove her home... 145miles round trip! Averaged 17.5mpg.

A quick way to see if the bore is just built up aluminum from the piston is to use muratic acid. It will pull off the aluminum without messing up the iron. We used to do this when we stuck 2 stroke racing cart motors. A light hone, new piston and back on the track. That one looks pretty rough though.

Good info!
I am sure there is a good amount of aluminum deposit at the top of the bore, but I doubt thats the real issue!

Today, it was time to go thru all the parts, and decant from the myriad of jumbled bits into a logical.... well .as best I can.
This way I was able, in a fashion to see what I have, and make notes on the obvious stuff...
Then I can store them away for later, therefore making space to the other parts...

The rockers, push rods, head bolts, and a bunch of other stuff, were in a bucket...
No clue what was matched with what at this point...
Not my way, but we will survive!

So, I emptied the buckets, boxes and tubs of parts, and arranged them in a logical fashion...

Rocker Covers, Rockers, and Pushrods, bagged, tagged and boxed!

Inspected the Turbo, which I think is serviceable, but needs new bearings, as it has some play in the tubine.

All that done, I broke down the head, into parts, labeled, and bagged.
Again, everything looks good, and nothing scary.

Head itself looks great, but the valve seats might need a light cut, but the valves themselves were great, and the valve guides felt very good.

Final bonus of today was finding the missing chunk from the Timing case, where the dowel pin fell out, and blew out the wall.
I think I can TiG weld it back in place!

The Range Rover and Toyota Landcruiser are the kings of SUV's......with the emphasis on the "U" for utility part. The rest of the SUV crowd are just to make woman see better, and feel "safer".🙄
