67 289, Factory Air, Power Steering, Front Power Disc Brakes, California Emission, Deluxe Pony Interior. Stored the past 27 years. In restoration stage. A few years back I started the restoration of my 67 that has been in storage for 27 years. It had a cracked timing chain cover that I replaced, but I ended up with a water leak. Disappointed, I put the project aside. I started the project again by going back to the block and installed a new set of gaskets. Evidently, this was not needed because I found that the longest bolt (labeled EY) on the bolt kit drawing, which should be 5 inches long, is bottoming out in the block and not tightening the gasket. I removed the bolt and measured it. It was 5 1/2 inches long and looked to be a substitute from the original. However, a 5 inch bolt does not reach the block. This bolt goes through the emission pump/alternator bracket through the water pump and timing cover. There seems to be water on the bolt threads. Could the bolt have caused a crack inside the block? I used a proper torque wrench setting each time the bolts were installed.
