The main problem is valve seat burnout and loss of compression due to
Look for the cause of failures in traction in the turbine control system, DMRV, USR valve
The culprit for the oil leak here is most often the bursting lower flange of the VKG tube
The ribbed belt due to a breakdown of its roller sometimes gets into the timing and the end of the motor
