5 pages deep, but on the back cover it finally tells you how to prevent unnecessary repairs.

I've had crankshafts for gas V8's balanced for $60. I think the whole blueprint job costs about $120 ish. With a little know how and a scale you can weight match the pistons and rods yourself.

I believe the solution to this problem would be to have the entire rotating assembly machined and balanced as close to perfect spec as possible. I've read that the cranks are a little out of spec from the factory, and that the pistons and rods are not weight matched very well.

Anytime you are towing or climbing a hill if your giving it more throttle and not gaining any road speed you are lugging.

I suppose we should get back to the 6.2L discussion. The nice thing GM did for you guys was they made a ton of those engines. So even if you have a problem with one you can cheaply replace it with another zero mileage rebuild. If I was ever going to buy another military 5/4 (which I don't...

I hate fear mongering of any kind, and I try not to do it. I guess the only thing I can give you now is an example. You would think the designers of the biggest and most expensive diesel engines in the world would want to design the most simple and efficient engines that they possibly could...

Hey, I owned up to that. I didn't mean for that post to come off the way you took it.

I can respect your experience and would like to learn as much as you know. Unfortunately I have no physical documentation to prove what I say. Like I said it's just personal experience and what I have been told by the people in the know. I'm like you I just want the right answers that's why I...

I'm a carpenter/metal fabricator. I can build most anything out of wood or metal. I don't do mechanic work for a living because I like it. I don't think I would enjoy it as much if I had to do it for a living. I didn't want to call you out but turnabout is fair play. You seem like an...

By the way, does anyone remember what we were all talking about?

Sorry, the diesel engine was invented in 1897. Had to look it up.

1987 was not 50 Years ago, and diesel engines have been around for maybe 100 years. The patent was on the inline 6 cylinder design. Detroit Diesel was forced out of the 2-strokes by the EPA and needed a new engine design. No I do not build engines for a living just for a hobby. I never said...

For someone who is as in touch with diesels as you are you should have known that Detroit Diesel-Allison built it's first 4-stroke diesel in 1980. They had to buy the patent rights just to get into the 4-stroke market. Pancake engines are opposed piston engines. These engines are the most...

The 6.2L engine was designed for GM by Detroit Deisel. It was one of Detroit Diesel's first steps into the 4-stroke market. You can tell that Detroit Diesel was kind of new to that game. Though the 6.2L is not what I would consider the worst diesel engine ever. I have to give that tittle to...

I was referring to the cancelation of forces in an inline engine. There are always pistons traveling in opposite directions from one another creating less harmonic vibrations. Fewer vibrations means less stress on the block which means less stress on the crank. The V8 design imposes stress...

These engines run a very high compression ratio, something like 21:1 I believe. This kind of compression produces an extreme shock load on the crankshaft. If you lowered the compression and installed a turbo or supercharger it might save the crank.

I was zinging all V8's not just the 6.2, and was just trying to explain the physics. I too own a few V8's, both gas and Diesel so I believe I'm allowed a little say here. By the way the solution to the broken crankshaft problem is an aftermarket forged crank. There are a few companies that...

I've got a good experiment that all the V8 fans can try at home. Go to your local junkyard and pick yourself out a couple of old junker engines that still run. They don't even have to be diesel for this, but you need one V8 and one inline. Set them up on engine stands, and flip them over...

Why do you think there are so many threads on 6.2L crankshafts. Go ahead, Google "6.2L broken crank" tell me what pops up. Inline engines are a better design. You can't throw pistons and rods at a 90° angle from one another and expect it to be an efficient design, any engineer knows this...

Inline and opposed piston engines can get away with less rotational counterweight mass because there's equal weight traveling in the opposite direction of each firing cylinder. V8's don't have that advantage so to compensate they must utilize more rotational mass to keep the engine balanced...
