But I got it off, all looked ok underneath, there was a LOT of an RTV like substance around the plate. I decided not to dig into it at this time. I know that's probably where the leak is and that it's still going to leak, I just don't have the know-how to tear in that deep.

So, I started to button it all back up. 2 things:
1. Why do I have to put the pully back on before torquing down the cover bolts? I did it because it's recommended, but I don't understand the need.

2. I don't have a torque wrench that could possibly fit behind the pulley. So I got them "snug" but not too tight. Good enough?

Now to get a new water pump gasket and probably some new hoses and see if this project at least REDUCED the leaking.
There is some play in the placement of the timing gear cover before all the bolts are snugged down. Keep them loose, then put the crank pulley on to center the cover. Then tighten down the bolts on the cover. Everyone knows, or should know that the bottom two, the big ones, get some RTV on their threads. As I posted above, a little smear of RTV on each side of that cork gasket will make future removal easier. It is not needed for sealing. Do not over torque the bolts for the timing gear cover, like oil pans and side covers that will deform it and make it leak. The factory cork gasket works great and is very forgiving. As with all seals, smear some grease on the timing gear cover seal before putting the crank pulley on.
