There are small vertical scratches and I didn't know if they are fine or not, and didn't want to take a risk.
Anyway I think I got the wrong bearings, I should have get H1042/5
Actually it is the right model.

Please, look for the size markers on the old bearings.
Please check the size painstakingly. https://www.motointegrator.de/artikel/13...h10425-std
If in doubt, please reuse the old bearings.

I bought the right dimensions from King, after measuring the old ones, and they sit good.
I need to buy a new water pump because the bearing is a little worn.
And I'm waiting for the honing tool to hone the liners.
This is the big end bearings which I bought and fit:

Can anyone tell me what's the width of the big end bearing? My old ones were 17.7 mm. So why all manufacturers say it should be 20.75 mm?

I do not see the C3G in the compatibility list for the CR4426AM bearing set.
Besides, if the width is 17,01mm and not 17,7 and not 20,75 either, why did you order it?
Why do you think I wrote the quoted stuff above?
You also have to observe that you don't buy "oversized bearings", usually by 0,25mm ore even more.
The oversized is in quotation marks because they are usually undersized (the bore) and intended to be used together with a revised crankshaft.

Don't mix up the main bearings with the big end bearings.
The small size is used with revised crankshafts, the bigger size with the original crankshaft.

Perhaps C1J engine. Look for the engine plate under the cylinder head.

Mine are 17.7 mm same as the King engine I bought. I compared them and they look identical. I bought the standard bearings.
That's what I don't understand, why they say that c3g should have 20.75 mm.

Also, what do they mean? that I'm supposed to change the order of the used liners and their pistons to achieve the correct protrusion?

You don't have to do that if you reuse the old liners because they should have been perfectly aligned in the factory.
The protrusions are wildly exaggerated just to show you how to arrange the liners in case that they are new and different in hight.
I wouldn't even care to measure.

I removed the valve cover and checked compression again and I have
1. 7 bars
2. 3.5 bars
3. 3.5 bars
4. 7 bars

Yes, he did and caused me a lot of effort because of his unprofessional job. Look at the water leaking from burning chambers 2 and 3.

I opened the oil pump to clean and inspect it. The retainer of the oil pressure valve which looks like a washer wasn't seating properly when I closed the oil pump or it is supposed to be put in one direction. It deformed the bore and the washer and it couldn't go in the bore anymore until I removed some material but now it sits tight instead of free.
Watch when you do it.

Putting back the oil sump was not fun at all.

You can also see here why the a/c compressor blocks the way. Even when removed. its mounting prevents you from raising the oil sump straight up.

I hope I won't have leaks.

Sorry, no, But I will show you the diagram. The marked part was not sitting well and was deformed when tightening the pump screws.

Same problem after second rebuild. I will see if I can leave with it or salvage the car.
