4HE1 problem
Hello, Here’s an update. My truck has been checked by two mechanics, one of whom previously worked for ISUZU. As we had all diagnosed, it really is a timing issue. My injection pump needs to be set at 8 degrees and not 6 degrees before TDC (it’s even written on a sticker inside the cab). After... -

4HE1 problem
If my theory is correct, only my crankshaft is out of alignment. The injection pump and the camshaft are properly synchronized with each other. So if I adjust the timing of the injection pump, it might become synchronized with the crankshaft, but the camshaft would then be the only one out of... -

4HE1 problem
Yes, I tried everything I could without removing the engine. It’s definitely a timing issue, but how did it happen? I only changed the head gasket. After all these tests and thoughts about how this engine works, the only explanation I can see is a misalignment between the small gear and the... -

4HE1 problem
Hello, it’s possible that you have a worn head gasket, and that a bit of coolant is leaking into the oil passages (coolant in your oil) and also into the combustion chamber (white smoke). But yes, I can confirm — white smoke can also be diesel. -

4HE1 problem
Hello, I tried to reproduce my initial error ("klac") by aligning my camshaft with the wrong mark. First off, I was really unlucky because it causes valve 2 to drop just enough to smash into cylinder 1 without me realizing it, since the rocker arms screw down fully without any resistance. If it... -

4HE1 problem
So it's possible. Either the key broke, or there isn't one. If that's it, it's really weird because I didn't force it, for me it was the resistance of the compression. I'm going to try to lock the camshaft and make myself a tool to turn the crankshaft, because turning it the other way unscrews... -

4HE1 problem
Hello, I'm coming back without any news but with some questions: Is it possible that the small gear has shifted in relation to the large one? Is it a single molded piece, or are they each press-fitted together? Because after my 10,000th check, it seems like my camshaft alignment might not be... -

4HE1 problem
It's probably that. But I don't understand how it could have shifted. It's impossible, it's a mystery! I'm trying to find another engine, but mine isn't available, only newer ones. Or it's in Asia, but with shipping and customs fees, it costs as much as the truck... I'm looking for a mechanic... -

4HE1 problem
Thanks again for helping me. If I set my crankshaft to TDC, my camshaft is perfectly aligned with the "B" mark horizontally on the cylinder head. As for the injection pump, I can see the marks, but nothing is aligned, which is normal. If I set my crankshaft to 13° or 8° BTDC (as per the workshop... -

4HE1 problem
I had already tried when the engine was bare. There was no change. But it was very cold, -5 to 5°C, which may have skewed the result. If I have to try again now, it's so difficult to access that I have to disassemble a lot of things, so I might as well take out the engine. But I don’t have the... -

4HE1 problem
Yes, I am sure, even after completely removing the intake, so with all four ports open and the valves visible, it's the same. My breakdown is supernatural! Incomprehensible! -

4HE1 problem
It's fixed. Oh no, that's why, I hadn't thought of it... false joy... Attached is a video with the injectors, I tested them all on all the outings, everything looks good. back to square one... -

4HE1 problem
Hello, Attached is a video showing the fuel injection pump outputs to the injectors. I don’t have a comparison, but it seems to me that the pressure is sufficient, especially since this is only with the starter. After a while, the fuel doesn't shoot as high because the batteries are running... -
B
4HE1 problem
Hello, no, I don’t know what to do anymore, but I’m going to test my injection pump differently. When I took the injectors to the diesel specialist, before doing so, I had removed, cleaned, and tested them outside the engine using the starter. This sprayed diesel everywhere, making it difficult... -

4HE1 problem
Thank you very much for your help! When I tested the pump pressure, I used the engine oil compression gauge that I had. Its needle is not stabilized by liquid, which made it hard to read. With the engine running, diesel was still coming out of the orifice a lot without the screw, and there was...
