thanks for all the thoughts. The rad is currently out being re-cored. A new one was something over 300 bucks, and naturally, the re-core will be "slightly" less, probably around 200. The rad had previously had a hole punched in it. It had the lines pinched off and was temporarily sealed...all before I had it. It finally had another tube let go and the water went out fast. I did not even notice that the temp had gone up. The tractor had not been running that long and I just flat missed the temp guage going up. The first sign I had was when the engine slowed and stalled.

The plan is to get the rad back, fill up the system and fire it up. Once its warmed up I'll change the oil and filter and then see what happens. I'm going to pressurize the system with air, through the radiator once its fixed and hopefully that might let me know if I've got an obvious head gasket leak. If there seems to be an obvious problem I'll try and rig up a leak down tester. I've never tried that on a diesel, but it must be doable and will normally tell me more then a compression test.

The blow by was definitely more then it had been previously, which was essentially nothing. However, I only ran it for about 30 seconds after re-filling it with water and I'd want to take a better look at it with more running time.

I guess we'll see after I have it together on Tuesday. Hopefully none of the pistons look like the attached. (some of you may have seen this picture before, I think I posted it in another forum)


If it shows some obvious problems then I'll do the in frame myself. Can't be all that tough

With a little TLC, you should be able to slip that one right back in, and fur-her-up!;)

hmmm...well it DID come out of a running engine, although one with a wee bit of an explosion.....

Looks like that one saw a little to much anesthesia!

It's pretty hard trying to keep track of the gauges all the time.:D

Flashing lights and an alarm tied in to the gauges would really help. Course there are those that would dislike this type of "Idiot" help!:D

I'd change the oil and filter immediately prior to running cooked oil thru it.

About the worst thing you can do to a diesel is to stall it while running it hard. I realize you had no choice but to turn it off. But for those of you reading this, if you stall your engine while working it hard, restart it immediately to help the cooling system disperse the top end heat. Let it run a bit prior to resuming the hard work and watch your temp gages.

If you have a suspect radiator that is on its last leg, you can add an overheat buzzer that will let you know about overheating conditions.

Yep, seen the results of too much nitrous before, do you have any sodium filled nickel alloy exhaust valves which resemble a flower pedal??? NO2 can turn a $100 valve into scrap pretty fast also. The acceleration when those motors are boosted tho.........oh la la. Man what a thrill ride.:D :D :D

Yup..got valves that look like all sorts of art objects, as well as pistons, rods, cylinders cases etc etc. Just like a diesel or anything else, if you run it too lean, you're gonna have some damage.
That particular engine runs on nitro methane, rather then gas or alcohol with a nitrous boost.
But you're right about acceleration. This bike goes 0-60 in about 1 second and 0-100 in about 2, so you pretty much need to be sitting back in the seat to go along for the ride.

Now if I can just figure out how to get that package into the new holland, it will make the field mowing job a bit quicker.:p

Does anyone happen to know the size of the adapter that fits the injection holes for doing a compression test? I'm guessing I collapsed the rings on one or more cylinders and I do not have an adapter that will fit for a leak down or compression test. Thanks in advance.
