I order my oil from Napa. Part #NP75118 is an SAE-40 CF-2 oil for the 2-strokes. You should use CF-4 for the 4-strokes, but I can't remember the part number for that.

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...

I picked up a couple of used 6TL Hawker batteries for $50.00 each from The Battery Barn in Petersburg VA. That was a couple of years ago and they still work great. My GPS was a little lost trying to find that place, but I just followed the smell of battery acid. That place had tons of...

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...

:ditto: Diesel engines don't wisper their complaints.

If you plan on keeping this truck for a while and want real world info on the condition of the engine then change the oil and filter. Run the truck for 3000 miles then pull a sample of oil out and send it in for analysis. They will be able to tell you exactly what condition that engine is in...

If you can't tell the difference between engine clatter and bearing knock then there is nothing to worry about. I've been around knocking diesels before. It's a gut-renching sound. Believe me you will be able to hear it.

That oil has changed dramatically in the past two years, and unfortunately not for the better. It's not a bad oil, just not what it used to be. Oil companies change the chemical formulation of their oils all the time, so it's impossible to say that an oil that performed well last year will...

If the heads have been off then you need to run the rack. That refers to injector timing and height adjustment. You need a 92 series service manual, and a few special tools. You also need to find out what number and color code the injectors have, and to make sure they all match...

How many car windows can you blow out at once with those?

Every inline engine is designed like that. It's what makes them so well balanced. A little blow by is OK, you just don't want to see alot of smoke coming out. I wouldn't worry as long as the engine runs good, doesn't knock, or make any other bad sounds. Unfortunately engines are only new...

ZDDP additives are liquids that you pour into your engine. However ZDDP itself is a solid. So what are you actually pouring into your engine? Also I have built quite a few high performance diesel and gas engines with flat tappet lifters, and have witnessed cam lobes wiped out on engines that...

But you were able to work on the truck and fix it. Imagine having two flat tires on the road and not being able to do that. What are the words that would come from your mouth? "CTIS sucks!!!"

A Dana 80 and Dana 70 are different axles. Some one ton pickups have Dana 80s with Dana 70 shafts. These axles are known as Dana 80 hybrids. If the axles your talking about are true Dana 80s then I would say yes, but no winch, no hauling, and no towing. What kind of budget are you working...

While I agree with the zinc-phosphorus issue I have to warn everyone that the zinc-phosphorus additives are not just zinc and phosphorus. Those are metals that are mixed with who knows what else. I have personally seen oil analysis and bearing wear tests that show how the introduction of these...

Awful lot of backlash for that post. I myself have made the mistake in the past of trying to improve an inferior product thinking I could save some money, but end up spending more than what the superior product would have cost. If you can get all the parts for cheap then by all means go for...

The military GL site that I bought my m817 at had a bunch of m923a2 trucks, and everyone of them had flat tires. CTIS sucks!!!
