On the farm.

Well just an update to my original post. Cylinder number one has a bent intake push rod. Exhaust push rod top was destroyed. I also have a destroyed tappet. Thinking about doing a complete rebuild since truck has 306,000 miles on it. Anyone ever experience something like this out of the blue...

hello all have a 1996 2500 12 valve Cummins with 305K. Today on way to work all was normal when I deaccelerated on the freeway and pushed in the clutch instant knocking noise from the top of the motor. I was thinking injector failure. I was able to limp it about 3 miles to work it does feel...

“Old thread...” What does that mean? I’m not sure how old your graph is but it looks like one that was developed based on what oil refiners call “straight run distlllates” That is, lower boiling point parafinic crudes have higher cetane and lower heating value. No argument there. Just like...

Cetane number is not a measure or indication of the heating value (BTU) of diesel fuel and has little if any affect on engine power output. The measure of diesel fuel heating value, or sometimes called energy content is API gravity. Typical #2 diesel fuels have about 35 API gravity. Lower than...

Hello everyone. Just bought a 1996 2500 5 speed. When I bought it I noticed a valve was placed on the coolant line going to the heater core. The previous owner stated that the cool/warm door in the truck work but the switch may have a vacuum leak so you open the valve for heat. Which does work...

I see the last time anyone in Minnesota met on here was about 4 years ago. Anyone meeting from here anymore? I used to have a 96 12 valve and would meet up with other MN TDR members. I now am back with another 96. Just wondering if anyone is still meeting?

Gentlemen, I am new to TDR and respect the experiences and opinions shared here. Yes, even if they differ from my own. Moreover, when presented with analytical evidence I have changed my opinion. Please recall that this tread started out with raxley trying to drill his exhaust manifold to...

GAmes. I certainly like the idea of monitoring exhaust gas temperature. It’s a good way to say something about engine load and thermal stresses. However, I must disagree with your analysis. Exhaust gas temps are a relative measurement. If you read the exhaust temp from the same place all the...

Simplify your life here. If you really think you need to monitor exhaust gas temperature, put the thermocouple within a couple of inches of the turbine outlet. You just need to learn how to read it (just like other engine operating parameters). Yes, it is true the gas temperature is higher on...
