      Did run today to full heat, till the fans start up. Oil press min was like 0.8Bar on idle. Revved also little. Sound is gone now when fully warmed up? Need to check tomorrow again when engine back cold.

      Aand sound is back. Did go buy a stethoscope and listened the engine. On picture (link below) you see orange arrow. The rattle is loudest in that spot i think. Also at blue arrow i can hear a silent knoking. Could it be bad oil pump? The sound doesnt appear when full cold or full warm engine. Also did "roadknock" test. Pushed back pistons whit long extension when pistons going down. All did feel good, did not move.

      still can't see the link there is nothing like a stethoscope to make your engine sound like it's just about to go bang very sensitive instruments. there is a chance your crank bearings are worn, might be worth replacing them as a starting point. if you've replaced the oil/filter and the pick up gauze is clear, its the next step I guess. check your oil pump while you're there

      Going to grap "new" (used but 100% working) oil pump on next week. If sound still there. i guess i need to tear up again timing chains and check if everything good on lower chain. Maybe replace international shaft bearing and chain gears same time.. After that i guess it's time to replace all crank and rod bearings.. Maybe working again whitout sound on next christmas

      I would do the bearings while you're in there. might just be what it needs.
