Ok in a few weeks i pull of the head make some pictures from cylinderwall and pistons.

Other ideas? Rebuild block or not?

Yes i must do this. So i can the shortblock let it be.

I think it comes from the headgasket. hot exhaust gases heating the water up and the water gives it to oil. Thanks for helping

First the oil temp goes up to 110 grad than the water temp go over the half mark. as i start the engine after 10 minutes cold down it runs on 5 cylinders after i pull the gas it runs normal on 6. Pull coils and sparks out tho check compression.after the test wi give pressure on the cooling system and leave it for 20 minutes. with an endoscope going in each cylinder to check it inside. At the 6 cylinder we are going diving. Water floating from headgasket in the cylinder thats why the car runs after start only on 5 cylinders. but no oil in water and no water in oil. it doesnt smoke from exhaust. but i have power leaks sometime when i pull hard but i think this comes from the headgasket too on pressure the gases pressing in to the water so they doesnt have a good mixture on cylinder 6. Thats why the car overheating. sry for my bad englisch

The headgasket is not changed the test results are with the shi××× headgasket
