What It Helps Correct

• Erratic ignition timing caused by a leaking vacuum advance diaphragm
• Slow or inconsistent timing advance during throttle changes
• Vacuum loss at the distributor advance canister
• Driveability concerns tied to worn distributor vacuum control
• Restoration needs for select 1968-1972 Oldsmobile ignition systems

Installation Notes

Verify distributor number and OE reference before installation, especially on 1968-1972 Oldsmobile Cutlass, Cutlass Supreme, Delta 88, 98, and Toronado applications with multiple distributor variations. Confirm the vacuum hose connection matches the single hose connector and inspect the vacuum line for cracks or restriction before final assembly. This part cross-references Standard Ignition V373 for the same application.
