Bob,
Look for the sign of fresh sealer around the timing cover. Also look for sealer at the intake where it contacts the timing cover.
Get under the car and look for the 4 bottom bolts that connect the cover to the pan. Most times they are dirty from years of grunge. They should show signs of being taken on or off. Any Mechanic would remove the fuel pump to do a timing cover on a Pontiac. It should also show signs of sealer around the fuel pump. Ask for the old
timing gears and chain. I always give them to the customer to check out!
