30 Series Engine Flaw

[D7E]

By artics you mean articulated models? What type of head problems and why with those specific types?

Hey i'm not a green lover but have had many over the years and some 30 series " and i mean SOME" did suffer from blown head gaskets and warped heads but no worse than the old " Ford porous engine blocks" or " CAT v8 Head trouble " it is but a few . Why would there be so many being used ?
