I'll look into more about the piston rings. As far as I know, they only had one flavor of piston rings. I just ordered the tractor service manual so we will see if that has any additional information in it. I believe the tractor pistons were different from the multifuel pistons. As far as piston...

Thanks Bud. I think I posted this before, but here is the "Long Break-in" procedure for an LDT that has had new bearings (does not apply to me), new pistons (does not apply to me), Pistons rings (applies to me) and new sleeves (does not apply but my sleeves will be honed with a 240 grit ball...

I probably need to collect some data and see what my engine is actually doing. Do a compression and leakdown test to get those numbers. I might be able to use a friends dyno but he is very busy and not sure when I could get on that. In the military rebuild manual, they dyno every engine after...

I thought I didn't a decent job at putting it under a load. I tried to put it under a load the best I could. Ill have to do a leak-down test someday and see where my numbers are after this 3rd overhaul. I'm about ready to throw in the towel and put a 4-71 under the hood. But if i rebuilt one of...

HAHA! Thank you for your support! [thumbzup]

But Mark now has the same issues with with his piston kits.... the truck lacks power and is hard to start. He is using 100% diesel. As far as me using some WMO in my fuel, the first first rebuild I had about 50% diesel and 50% WMO... and it ran good for a while until it started not to and...

Mark, Any updates as to what the issues are with your engine? I just wanted to double check to see what your experiences are. Thank you.

WOW Mark... I thought your engine was running well. Did something change? Mine ran good for a while (400ish miles?) after I rebuilt it as well and then I started getting blowby and poor starting performance (even when it was 60 or 70 degrees out). It sounds like you are having the same exact...

I put another engine in the truck. Before I put the "new" take out engine in, I honed the cylinders, installed new rings and bolted the heads down that came with the engine. I still think the heads were not the problem with my engine and it was the "new style LDS pistons" not sealing to the...

I know, it was eating at me too trying to figure out what the cause of the blowby is/was. I only had the problem when I put those new pistons in though. The truck never started good after that. I have the original LDT pistons in and I couldnt be happier. It runs awesome now. It will be neat to...

How many CFM is that filter rated for? I believe a stock deuce air filter was 410 CFM... please correct me if I am wrong. I would like to find something where I can flow a little more air through my air filter. Maybe find something somewhere, make brackets and modify it so I can install it under...

It is a TD block. This problem never happened with my old engine, only after I rebuilt it. They were NOS heads as well. Anything is possible, but geez, I wouldnt think anything would be cracked... or at least shouldn't be. Side note: How do you know your LDS piston kits are 20:1 compression...

I am very happy that your build is going well. I really wish I knew why my LDS piston kits did not work out. I am convinced that they were the problem all along. Also I believe the main bearings were worn some as well which caused the lower oil pressure. Not a junk engine by any means but it...

1300 is toasty. Are you using straight diesel? You have more hills in the common wealth than I have here in Michigan. I sure miss the hills. I sure wish there were easier options for our trucks to install a bigger air cleaner under the hood. I start to pull up my air filter indicator (new style...

I found this a while ago and it was listed in the TM-9-2815-204-35. It is talking about the LDS 427-2. I do not know if the cams were different with the LDS-427 and the LDT-465. Here it is anyway for the LDS-427:

How does it start when it is cold? Mine was a bear to start when it was cold (60 degrees F) when I had those new style LDS pistons. Right now with my OEM LDT pistons, my boost can barely hit 17psi and the EGTs never get about 1000 empty. I tried and had a little hill and it just didn't get...

Im glad to see they are taking care of you with the injectors. Stories like this are good and only helps a vendor build a good reputation. This is why I always like to check parts that I get like that. you never know what stuff you may get and its always good to know what parts are like that go...

I have an LDS in my M109A3 and that sounds completely different than my M35A2. I think that could be why. The rocker arms are the same on both engine (I verified it).

I went through some injectors back in the day pop testing them to calibrate them. you get them once in a while that leak a little and what not. Personally, I would still pop test the new injectors just so you know they are exactly what you want and that they are all balanced. I have a set of...

I thought I saw some nozzles online a while back. Did you try searching for the part number online? Are your injectors the shim style or the screw adjustable style?
