Digging deeper into the CVC reveals a genuine replacement stripped engine STC1965E Serial number AAA S15742 L9
The crankshaft pulley is marked as ERR5085 but has no oil thrower. Parts book seems a bit vague as ERR5085 is replaced by ERR7379 with ERR7374, the thrower.
Does the thrower actually do anything as once the seal has failed I would imagine throwing oil around is not helpful?
Does anyone know the history of the replacement engine serial numbers?
Thanks as always.
