Many discussions have occurred on this site about the cause of oil burning in the 6VE1...theories ranged from clogged EGR, to poorly designed PCV vacuum circuit, to finally cylinder 1 faulty oil ring set...

Had an interesting conversation with an engine remanufacturer who was providing crate 6VE1 engines.....I was basically asking whether his line incorporated service bulletins and manufacturer upgrades...so he said yes and rattled off some of the changes to that engine, which oh by the way included having to use a different type of ring set because the earlier ones were really the wrong fitment for that engine....or words to that effect

Remember many website bloggers relating how tight lipped Isuzu was about the oil burning problem and what caused it

This story certainly indicates that Isuzu probably made an engineering design error in its original 6VE1's
