Fairly consistent, but louder than normal, followed by inconsistent banging, clanging. The noise seems to agree with the liner issue for 1 piston. My guess is the liner was damaged partially at first but still mostly in place. After idling a couple minutes it slid down and broke up...

Thanks for the replies and good info. Disassembly is in progress. My plan is to do some inspection and figure out if any more damage exists. So far i'm leaning toward repairing it. I ran a tiny camera into the injector port and could see some chunks on top of the piston also as expected...

The cylinder liner at the front of the engine broke up and also took out the piston oil jet tube thing. Has anyone here done this repair and how did it go? Part 1: The noise it makes (I believe this is after most or all of the liner broke up)...

Video looks normal to me. When you step on the gas quick, I think smoke is expected until the turbo catches up. If it is smoky at idle or a constant rpm only while the air filter is in, I would replace the filter. It looks bad and they are available. Is the dirty filter indicator under the...

Can you explain what went wrong with the turbo? I'm just curious since I had (or possibly still have) turbo issues recently.

The nut did not get ingested. Luckily the blade spacing prevented that. It just rattled around and wore away the blades.

UPDATE: This is the short version:) I think I had the turbo in and out at least 5 times. Found a used type D turbo to replace my type D. Installed it. Test 1: Started engine and oil leaking all over turbo. Shut down with about a minute after realizing the oi Removed turbo again to...

While I had all the equipment ready to go I decided to do this as well. First post updated to add the voltage and current results.

Yes, fuel off so it doesn't start. I got the idea from seeing it done on gas engines. Look up youtube video: "Method for Relative Compression Testing to get PSI DATA!!". scannerdanner also has some good videos on this procedure. I updated the original post to include equipment makes/models.

Today I decided to try a 'relative compression test' on the M35A2. This method uses a current probe on the battery line and measures current peaks caused by the compression of each cylinder. There should be 1 peak for each cylinder, then the pattern will repeat as long as you are cranking the...

The giant phone number on the rear window was perhaps a poor choice.

The turbo came out without much problem. Just needed about 16" of leverage for the exhaust bolts. It looks like I found a used turbo i'm likely purchasing now, but still wan't to investigate and possibly repair the one I have. The harder part to disassemble is getting the cartridge assembly out...

I sprayed on some WD-40 and other penetrating oil. It has to sit for a few days until I can get back there anyway. In the meantime i'm looking up turbo parts and options. Would be nice if someone could find a way to make one of the $200-$400 new turbos fit and work. Won't be me anytime soon...

Update 7/7/2019: Wasn't able to get the 4 bolts that attach to the turbo to the exhaust manifold loose. Will go back with impact wrench later. Got picture of ID plate by holding phone camera backwards...: Model: 3LM-39 2nd plate states "Overhauled at TEAD DATE: 6 - 92"

Here is 7 miles later on arriving back at lake, viewing smoke and oil: https://youtu.be/25N-9t-1NvM

That is interesting. I was concerned about flames also, however I think I had so much oil, it kept things cool. Here is a 3 sec video of the smoke at my first stop just after noticing it. (before the oil started flying out): https://youtu.be/RIgnTUkwDr4

UPDATE 1: Thanks for the replies. I should have trusted my ears. I found this nut as shown: It appears then nut worked loose and fell off. Since this is the intake side, the nut was sucked against the blades over and over. The blades show extreme wear. It appears the blade is aluminum...

Here is how it looks now: July 3: Drove about 36 miles to lake with no problem. July 6: Drove about 7 miles and suddenly noticed very excessive smoke out exhaust as I was slowing to make a turn. Stopped at gas station to investigate. Among the 1000 normal Deuce sounds, I thought I possibly...

I would like to see this as well. (General Dynamics M1161 ITV-LSV 4x4 Growler)
