This is a typical VM CRD 2.5 London Taxi TX4 engine, awaiting strip down and examination to assess the reason for crankshaft seizure. Failure of the main bearings and surface cracking (fissures) of the crankshaft journals are common.
After dismantling this VM engine we discovered that the crankshaft had been starved of oil causing bearing failure and server wear to the main bearing journals. The crankshaft had to be replaced with a new one as the wear was more than the permissible amount allowed by VM Motori.
Modern synthetic oils very often allow high mileages to be covered with minimal wear, this being testament to modern lubricating oil engineering and proves the longevity of VM diesel engines, assuming that the owner ensures that the correct amount of oil is kept in the sump.
