Kubota L6060 Engine failure

Why I put Stanadyne fuel additive in every tank. ULSD needs all the 'help' it can get, IMO.

The CP3 in the Cummins is about as reliable as it gets.

But if you have one of the newer CP4-equipped ('19 and '20 I think) Cummins..... Yeah, do it. Especially if you live up North. Cold weather isn't real easy on any to do with diesels. I do't know about the Denso-equipped Isuzu in chevy.

It's also a good idea to use a good anti-gel additive if you're in the Frozen Tundra. A real good idea.

Back when gm was trying to come up with something to compete with the Japanese with, they invented the Vega.

Believe it or not, it was a good engine with one minor flaw. The block liner would detiorate right at 75k miles and the engine would grenade shortly after.

But when cheby was testing the engine..... Here's where they went wrong --

They used perfect fuel. Perfectly clean, zero-dirt, zero-nasty, zero-pollutant fuel.

And when people put them into service in the real world and used real-world gasoline....... The pollutants in the gas ate up the cylinder liner. Not sure what it was they used...... Calcium Carbonate or sumpthin. Not like today's Fords that use plasma-wire-lined cylinder walls.

Then there was the fiasco created by (who else?) the EPA when they discovered that ZDDP (zinc) destroyed Catalytic Converters.

So they made Oil refiners cut way back, or eliminate it. ZDDP was an important lubricant in oil for flat-tappet camshafts. If you've got an older 454 or another flat-tappet camshaft equipped engine, be aware.

And what's funny is -- Anybody here old enough to remember the rash of NASCAR engine explosions for a couple years? Right around 1990? It was a real thing. The Oil Refiners didn't bother to tell people. Not even Racing Teams that they sponsored. They couldn't figure it out.

Told my buddy about it years ago. He pooh-poohed the whole idea. He rebuilt two HP 454's for his boat and they didn't make it off the trailer before both camshafts disintegrated. He eventually solved the problem by putting weak springs in the heads and won't admit he was mistaken to this day. He's a mechanic. A good one. But like most mechanics (certainly not all) he's a bit of a Luddite

Just passin it along. Do with it as you will

Don't apply to me. All my diesels are pre 4. They all smoke, just the way I like it.

Never be a post 4 diesel engine on this farm

Only good Diesels smoke (some)!

Depends on how hard you work them actually. In reality the new ones smoke too, it's just the smoke gets trapped in that magic cannister and needs 'regenerated' or whatever it's called, whereas mine just comes out the stack and blows away.

If Rudy Diesel ever saw how his engine was castrated, he'd roll over in his grave.

I do sometimes miss the smell of diesel on a cool morning. I like my new tractor but it does not smell the same.

That and cigarette smoke in the air (outside). Even though I have never smoked, I like the faint smell.

I just want to see how this all works out in the end. Sad story for sure.

Sorry to read about your troubles. This sounds like an unusual problem (since I don't recall reading any other threads about something like this). I would do the fuel test for a couple reasons. First it will show good will to Kubota, like you are willing to do your part. Secondly, even more so that if it comes back as bad fuel someone would need to explain how that caused the ECU to fail. Hopefully Kubota helps you out with the bill but out of warranty is just that.

I have absolutely nothing against clean air, clean water, clean fun, etc.

What I object to strenuously is an unelected, unresponsive, unacountable goobermint bureaucracy coming along and FORCING unproven, untested technology on us that WE have to pay for.

That DPF? Who do you think is paying for that? The Fairy Princess? You are. I am. The Company passes the cost on to the end user. Every time.

And when that ridiculous, absurd, half-azzed-engineered pile of garbage breaks down? Guess who pays for that?

You do. I do. Under warranty? Guess who's paying for that warranty? You don't think they're free, do you? The warranty is priced in. And when the warranty is up?

Four thousand dollars to remove GARBAGE from my Diesel Truck that I didn't want put on it in the first place. Because it kept breaking. Because the engineering is way behind. It's even worse on some makes of tractors. You can't touch them at all.

Because the EPA is a rogue organization that needs to be shut down, Then we can start over. Maybe with one that doesn't recruit from Eco-Terrorist organizations. Oh yes, they do.

Sorry about the rant
