Diesel truck discussion

"Cummins set the record straight in their May 2013 newsletter, outlining that Ford Motor Company had purchased 10.8% of the diesel engine manufacturer in 1990. In 1997, those shares were bought back, and as such Ford has not owned a stake in Cummins since.Nov 10, 2013"

So using this theory

I own Amazon because I bought their stock..................

 

The fuel system like stability, if your buddy have viered away from OEM there is a possibility this is his issues. I had River City injectors they were junk 6 of 8 leaked out of the top of the injector. My buddy is a Catipillar mechanic he made a fitting to install the injector in and bench test it on the Flow bench. I went back to OEM they all tested fine. The fuel rail in the head had to be rebuilt. All the orings needed replacing, we used Cat and John Deere orings. Also up graded the stand pipes and dummy pipes.

 

Yes...as long as you buy a measly 10.8 %

 

Many of them were electrical. IE; sensors and modules, wiring harness and connectors...
valve cover gaskets/wiring harness combo

 

The idea of a diesel used to make sense to me, but all that emissions stuff just made me not want one. Its not so simple as just removing the emission crap and deleting it. we have emissions tests here on newer diesels, and there's no way you'll pass with a deleted truck.

 

We are into my buddies 7.3, hpop replacement, rebuilding the harness’ all new connections(they were rough) coming out, turbo rebuild, new downpipes, fuel rails rebuilt. New manifolds all new gaskets. It’s a 12,000+ hour motor. It will be up and running in a few days.

 

Yes, sadly they've pretty much ruined them imho. My old 87 6.9 IDI still runs fine, makes no power & pulls the rest of the old rust bucket just fine. Starts everytime & away it goes.

 

Memories, I had an ‘83 6.9.

 

Nice!
it'll be nice to see it come back to life!

 

Around here it’s not broke until it’s not worth fixing anymore. It just needs some love.

 

The old 6.9's and pre PS 7.3's respond really well to a Banks turbo kit!
Oh, and BTW...anybody know that Ford had 3 diesel options in the F250/350 in 1994?

 

For older trucks diesels make sense, but for new trucks I don't really see the advantage? Unless you're consistently towing >10k pounds, a diesel is more expensive to buy, and more expensive to run, given how much more diesel fuel is relative to 87 octane, and you don't really get that much performance/reliability advantage.

Not that people buy trucks for what they need

 

I only need my motor to get me another 450k that should get me to retirement.

 

I have a 2000 dodge 24v that I really like, gets good fuel mileage, & will pull a house. it has 285000, miles & still runs good. 4x4 auto.

 

Ford purchased 10% of Cummins in 1990, and sold it in 1997.

I've driven diesels for 25 years, anywhere from the doggy Ford 6.9 to the 425HP Caterpillar in my wrecker. Everything in between for company owned or personal vehicles.

I think that my run with diesels is coming to a close at this point. I don't tow anything anymore, and the unreliability that the epa has caused, combined with the enormous cost of the engine just dont make sense for me. I mostly drive a company car, so the mpg loss wont bother me much.

 

I agree with this. I wanna give it a couple years before I dive in though. For what they are extracting I feel it is too small, but technology makes things possible.

 

That's about twice what l paid for the 87. The 96 ps is bone stock & no rust. That pulls the wood trailer in the summer & l'll likely leave it alone till it needs work.

 

Somewhere from the cobwebs of my mind I recall that a straight 6 is the most efficient engine design.
Makes sense to me.
2 rotations of the crank to complete cycle, that equals 720 degrees rotation, 720/6 cylinders = one cylinder firing every 120 degrees.
very well balanced without massive counterweights.

My Dad always bought plain jane pickups when he ran his business back in the day. Back then that meant a straight 6 with a 3 on the tree.
I always thought the straight six was a very good dependable engine. Ford, Dodge and GM all had very good straight sixes.
My daily driver has a straight six. A smooth and silky engine.

Of course I'm talking about gassers but the theory would hold true for diesels too.
