Burnt Cylinder Head: Causes & Repair

Hello!

Today I saw a strange engine failure; it was the 1.6-liter turbo diesel engine from a T3.

The engine apparently seized up on the highway and stopped running.
Okay, head removed:
My photo is unfortunately blurry/unclear, but I've never seen anything like it.

The cylinder head bolts were all relatively loose, and some of the bolts had what looked like sintered metal dust on them, which was a bad sign, indicating that the cylinders were full of water.
And then, it appears that the flame escaped through the gaps next to the swirl chambers in the two inner cylinders, and ejected a significant amount of material from the cylinder head towards the center of the cylinders.

Sometimes, to the extent that the valve seats are exposed.

Of course, these are all clever people,
Approximately one year ago, the cylinder head was replaced, and during that process, the cable to the glow plugs was apparently torn off. Since then, the engine has been started using starting fluid.

Kennt jemand so einen Schaden? Or the cause?
I've seen a lot, but I've never seen anything like this before...

I can take a photo if you would like, and possibly add it later.

Hi Steffen,
The engine was running without coolant until it stalled. I've experienced this before with a T4 engine with ABL and a Volvo D24Tic.
The water on the pistons was the first attempt at repair .

Best regards, Kurt.

I've seen something similar before, on an E39 with a 4.4L V8 engine, where everything had melted.
"Even with an E39 525Tds, you can run it without adding water for a very long time."

Sure, please provide the text you would like me to translate.
Has anyone ever seen anything like this before?

Hi,

What do the cylinder bore surfaces look like?

Hi!
"It's all junk; they were full of water for a quarter of a year."
I just saw that the plastic insulators on the glow plugs have even melted.
So, he was really hot back then.

It surprises me that the lubricating film lasted so long at those temperatures.

The chambers, on the other hand, still appear relatively healthy in terms of cracks. I've seen much worse on the 1.6 models, especially when there was enough water inside.

.
Because the cracks in this engine have fused back together .
It's a shame that VW didn't equip the 1.6TD engine in the T3 with a proper oil cooler and intercooler.
Then they would run for much longer.
And then there are the VW Beetle transmissions from 1938 .

mainly because the left side linkage rod from a Passat 3B fits quite well into the right rear light assembly.

In _that_ case, an LLK (Low-Emission Vehicle) wouldn't have made a difference either - because no engine is designed for such incompetent drivers .

This summer, I'm installing a BMW 740D intercooler on my T3 with a 1Z TDI engine.
Just good enough for the air conditions underneath the car.
Before that, I also had the Passat LLK.
I'm already curious to see how it will perform after the reconstruction.

"Ha . I know that very well from people who drive with the warning lights and temperature gauge in the red zone and think, "What is that? Oh, I can still make it to the next parking lot."
