Blocked oil return path, wrong size seal or/and worn mounting surface?
There is pressure limit valve & spring setup close to oil filter at lower front corner of the block. It should limit pressure to maximum 8 bar by releasing oil back to intake side of oil pump. It can be tested with external pressure gauge using WSM instructions. Sometimes valve will release too early even with new spring. I haven't seen factory spring which would allow much over 8 bar no matter what number of washers are added as long as piston has space move to open position.
what if the pressure becomes more then 8 bar, when you let the rpms rise till the next shift (say 6000 rpms (it's a automatic))?
