I am having to replace the Timing Cover, Chain and both gears. I pulled everythig of and with out moving the cam shaft or crankshaft put the new chain and gears back on. I noticed that on the gears there are on both gears 2 small counter sunk holes are they supposed to line up? I am at the point where I am puttong on the Timing Cover and thats when I noticed this.
