If the coolant is coming from inside the exhaust it's most likely a head gasket. A cracked head or block would do the same thing, but thankfully on the LDS/LDT motors the head gasket is usually the problem.

Heat up the knuckle around the stud then try another extractor

Well, making progress now! Just paid for the engine, now to arrange shipping. Transmission does not come with it but that's not a concern, wasn't a trans I wanted. 1982 International DT466, the 180hp model with about 150k miles on it. Power steering pump, air compressor, and 12 volt alt...

head gaskets and upgrade to head studs, you're already there

The block is not the weakest link in the multifuel when it comes to making more power. The head bolts and head gaskets is the first mechanical weak link to go. Turning up the fuel to match the maximum efficiency of the turbo (low-mid teens for boost from the C and D turbos) would be a great...

Care to post the email from them explaining the details? In this idiots statement I did not say that air pressure and load were the ONLY factors in the speed rating. None of us stated that it won't come apart at speed, but an increase of 5-10mph should not be a problem. I run 395's.

To circulate the oil before firing up the truck you could disconnect the fuel outlet line from the injection pump and crank the motor over with the starter a few times. 5-10 second cranks, 3-5 times. That way the engine gets lubed at lower rpm's, and the injection pump has fuel flowing through...

Remove the oil pan to inspect the bottom end and pour some oil on the crankshaft. Best time to replace the oil pan gasket and rear main seal if it looks questionable. prefill the oil filters, remove the valve covers and fill your engine oil from the top working your way across all of the head...

camoyj7 have you turned up the multifuel or are you still running stock with the engine?

That's a "power line pusher". In Iraq they hang the power and phone lines low. Without the pusher they tend to get caught on the turret and rip down the lines. The front and middle mounts on my truck(right truck in the pic)broke free and started swinging into oncoming traffic during the drive...

depending on your use there are 3 turbos that work very well on the 6.2 and 6.5 engines (all parts interchange, 1981 heads have a unique glowplug). HX35-great for unloaded around town, little restrictive at high rpm but better than any stock turbo from a 6.5. HX40-takes a few rpm's to spool up...

No, newer tires rolling at 55k pounds.

Calculating it off of the RPM's and gearing. I know in Iraq we usually drove our MRAP at 60-65mph (speed limiter at 65). Only tire failure we had was when the truck got airborne.

The tires speed rating is figured with the tires at maximum pressure and load.

By design they're not providing a fire in the intake. Like you said spray some ether on that red hot heater and watch your eyebrows haha.

It's a grid heater in the intake. Imagine a piece of chicken wire being electrified until it glows red and heats up the surrounding air, that's basically what it does. No flames like what the deuce has. Cummins runs a similar design on their 5.9L engines.

Might be able to have it machined for a larger diameter plunger.

Every large engine I work on uses an ether system.

White made the 465 as both a multifuel for the military and a diesel only for tractors. The turbo, pistons and head are different. Lower compression ratio on the diesel only model (18:1 is what I read).

Could get a custom cam ground, probably 300-500 bucks. To get the most out of a better cam the turbo needs to be swapped out to a more efficient design and less restrictive with exhaust flow to reduce the EGT's. Since your stated goal is another 30-40hp it can be safely done with the LDT...
