Why do you need a timing cover on a Pontiac?
Keeping a Pontiac engine cool is vital to it lasting. We get a lot of questions regarding timing covers and water pumps. We have taken the time to show each timing cover and address the ways to identify them.
What was the timing cover for a 1964 Pontiac?
Early 8 bolt designs are notorious for cooling issues. The 2pc plate we sell without the notch works in all 1964-68 models regardless of timing cover. These 2pc water pump plates take a single water pump gasket. In 1969 the 11 bolt timing cover and water pumps were introduced with much more efficient cooling.
Where is the 8 bolt plate located on a Pontiac?
The plate is now located on the outside of the cover where it seals off the water in the timing cover. The 8 bolt plate sat inside the cover and had no sealing around the edges nor did it seal against the water pump holes.
