Oil level regulator groups are attachments on these engines. A new longer vent line is used in these oil level regulator groups. This longer vent line is routed to a higher location on the engine. This change will help prevent oil from collecting in the vent line. The oil that collects could block the vent line. This could result in a incorrect oil level in the engine sump.

The illustration identifies the components that are required to replace the shorter 8V-0536 Hose As with the new longer vent line.
