Replacing The Oil Cooler Figure-8 Gasket
Given enough time, the replacement of the Vigors distributor O-rings and oil cooler O-rings is seemingly unavoidable. Heres a walk-through for the oil-cooler O-ring procedure provided by Heimonator, a relatively new member who's quickly making a name for himself.
If everything goes right, the first time repair should take about 2 hours. With experience, it can be done in about an hour and a half. Special thanks to Lvmilkman202s earlier message posted on the Vigors message board and this website's FAQ page.
Dealer cost for the Figure-8 O-ring and hoses were about $4 each. Oil cooler O-ring was about $3. Dealer told me oil cooler O-ring part number had changed from previous # 91316-PE7-730.
