4HE1 problem

[HATCHEQUIP]

Does this engine have copper washers under the injectors down in the head if it does are they correct should have only 1 per injector ive seen where they would get double stacked smoked so bad you couldnt be around it and slobering fuel everwhere. The spray pattern doesnt hit the dish or cup in the piston correctly. Other possibility headgasket to thick and lowered compression, need to test comp.

Yes, there are copper seals on each injector. The diesel specialist had informed me of this possibility where the spray could hit the well, leading to poor combustion due to seals that are too thick. The copper seals I use are new (Chinese) and appear to be identical to the original ones. There are no other options available for me to choose from...

As for the head gasket, I previously had doubts with my Chinese gasket and my resurfaced cylinder head, but in this case, everything is new and just like the original.

Hello, I haven't received the compressometer, I hope to get it tomorrow. As for the Reddit videos, do you have access? Because my post hasn't been published...

 

[mekanik]

I have not been able to access them.

 

[bibabo]

Oops, I don't know how to do it... I'll look for another way.

Grrr...

For my compression test, I will connect through the glow plug well. Is it better to do it with the engine running? Or with the starter for a few seconds?

If I do it with the starter, how can I prevent the injection pump from sending fuel into the cylinders?

In the photo, the bottom cable allows me to stop the engine if I pull on it—does it cut off the fuel to the injectors?

Thanks.

 

[mekanik]

Do it with the starter. 4 to 6 compression strokes and the gauge should go as high as it will go.
Pulling the shut down cable should shut the fuel off.

 

[mekanik]

The engine should be warm when you do the compression test.

Thank you for the information. Still haven't received anything for now.
I’m adding two links for the smoke videos. One shows when everything was disassembled, and I realized it was unburned fuel. The other shows the engine fully assembled as it is now. If the links work, I’ll add them to the first post. Let me know.

 

[mekanik]

Both videos work for me!
Someone did not accidentally top up the fuel tank with gasoline by chance?

 

[bibabo]

Cool!!!
I had the thought. I drained the tank as best I could. With a new fuel filter and a purged water separator. Currently, there are 10 liters of old gasoline mixed with 20 liters of new gasoline. There has been no change...

 

[mekanik]

Gasoline?? You mean Diesel?

 

[bibabo]

Yes diesel, the good liquid. It's the correct fluid. But since it sat for a month without moving and the temperature dropped to -5 degrees for several days, maybe it deteriorated.

In the second video, you can hear the engine's cold idle (higher) for a few seconds. The engine runs smoothly at 80/100, acceleration is good, and it smokes moderately—but it's still not great, and it smells bad. Then, as the engine warms up a bit, the idle speed drops, and that’s when the disaster happens. I don’t know which sensor, probe, or mechanism is causing this.

There is a screen in the separator assembly filter head. Undo the clear bowl and spin out the tin insert, then pull the flat screen.
I find it easier to remove the whole unit and place it upside-down in a vise.
On my '99 & '00, that screen was nearly plugged solid.
Ironically, the aftermarket unit i installed did not have the screen.

 

[bibabo]

What are you thinking? That the injection pump isn't able to draw in enough because of a clogged separator? Where exactly? I'm having trouble understanding the translation.

 

[heymccall]

#29, after unthreading #42.

 

[bibabo]

ok, I'll take it apart to see.

Hello, I was able to perform the compression tests: my 4 cylinders are at 23 or 24 bars (about 340 psi), while the workshop manual specifies 31 bars (about 440 psi). I definitely have a compression issue identical on all four cylinders, which must explain the poor combustion. What do you think? What could cause this on all four cylinders at the same time? A major internal crack? Thanks.

If I test the compression by removing the camshaft, so all the valves remain closed, can I do it, or do I risk breaking the connecting rods?
