Initially, I was looking for extraneous noise in the timing belt, and in the end I replaced the main bearings. I have already carried out a similar procedure on another YUMZ-6, more than a year has passed and the pressure in the lubrication system is about 1.5 on a warmed-up engine at idle speed, and initially it was 0.2-0.3 on a warmed-up one, taking into account the clamped pressure-reducing valve on the centrifuge. Now I will see what happens with this engine.
