I might have found more information on piston rings for the new style LDS Pistons. These pictures seem to show only two compression rings which indicates to me that they are the new style. I still have not found anyplace to buy replacement rings for these new style LDS pistons.

I found in another thread that somebody did a compression test on their engine. They had some issues with a cylinder not firing, but the highest cylinder pressure they got was 450psi. It's a good thing to note if I am putting this together and want to know what other people are getting for...

I'M glad. That is why I am trying to put so much energy into documentation. I want the next guy to learn something more about these things and maybe learn from any of the mistakes I might have made... like buying new piston kits when I would have felt better re-ringing my stock pistons.

Still say we should do an emissions test on it since we are running it on a dyno. We'll have to record it too so we can show people what a multifuel looks like blowing up on the dyno. It would be my luck. Oh well. sorry for being negative Nancy. This project is taking forever and costing lots...

That is how I feel with this engine rebuild even before I turned the first wrench. I knew something wouldn't work out right. I'm just nervous about cranking the engine up that much on the dyno. I'm just nervous it will come apart (since 2600 is a lot of RPM for a older bigger diesel like this)...

We did not pressure check the intake other than when we pressurized the cooling system with 7PSI at the cap. What are your thoughts behind the intake? How would an exhaust manifold cause moisture in the crank case? Thank you for ideas.

I just want to say that even though we seem to be throwing around ideas, I appreciate hearing everybody's own wisdom and experience. Even if somebody has one idea that may not be right, it may clue us in to something else, etc. The idea is to learn from this so I can help out the next guy and...

I'll give $337.29 :beer:

I wouldn't mind Having one of those. Those are 300 gallon I believe. How long has it been sitting? I'm sure all the brakes would have to be gone through, wheel bearings packed, etc. I would consider that in the price. Did you already buy it?

Check your idle speed adjustment. it should be set at 800rpm. I like 800 personally because it does not shake as much as around 700rpm or 750rpm.

I agree. These engines are not crazy complicated and I pay very close attention to detail. I have my buddy helping me and with two experienced heads and 4 eyes looking things over, we would catch something. With everything we see and the DATA we have, the piston/rings/cylinders is where all the...

When I took off the rear head, the nuts didn't seem to be as tight as the fronts, but there was not any sign of leakage on the gasket or the head. I am going to assume that isn't the cause of any problem right now. A possible cause of this sludge is the large amounts of blowby in the number 2...

Distortion where? So say I get new pistons, same ones I had before and put it all together. I basically have the same thing I did before. Now, how do I get it to have less than 10% leakdown after I hit the starter switch? Were the parts junk or was my break in procedure wrong? You look up a...

The cylinders seem glazed. I'm tempted to just hone my cylinders and reinstall the pistons (new style with 2 compression rings) with the same rings to see if the break in was an issue, but that is taking a chance. Do I need need new rings though ASSUMING that a break in was an issue... lets just...

Nothing. The heads were fully assembled NOS heads. Completely brand new.

Here is the thing. If a theory is the break in, why would one cylinder be at 95% leakdown and the one right next to it be at 15% leakdown? That is the part that confuses me.

Rip the sternum right out of the truck.

Yes, very frustrating. Surprisingly, I'm holding myself together with this project.

I looked a the cylinders and they do look awful shiny. I am wondering if the cylinders are glazed? I can still see cross hatch though and I thought glazed cylinders are when you cant see any cross hatch.
