Here is what I'm doing:
Timing Cover Gasket
Front Seal
Thermostat
Coolant System flush

I pulled it all apart to where my next step is opening up the timing cover (that harmonic balancer nut is a PAIN!). I had a pretty good oil leak and things are pretty oily.
Question: Should I use some type of engine cleaner/degreaser before I open things up? Can I use carb or break cleaner inside this area after it's open?
Befor or after, either way will work. It is probably easiest to clean it up as much as you can before removing the cover. If it is typical cruiser gunga, a scraper will peel most of it right off. Then hit it up with brake clean and a rag should get you back to clean.

I know you already have it torn down a ways, and this may not apply for you... but ... if you clean it down and then run it, you should be able to confirm it is your front seal, or timing cover gasket, or two lower bolts, or oil making its way down from the filter or oil making its way down from the valve cover or oil from the oil pan gasket. Of course, it yours is like mine - a combination of all the above.

Question: Is it a mistake not to do the plate gasket when I have it torn down this far? I can't say for sure if it's leaking or not, it was too messy to tell where the leak was coming from.
It could be the plate, once you have the cover off, you need to check the oil squirter to insure it is not tightened up to the point the plate is bowing out. If the squirter is not too tight, you should not be leaking from the plate.

FIPG is a good call. Use it on the gasket as well as the lower bolts. The gasket is thin and you will need to be careful as you tighten the cover. You want to get a good seal and it is fine line between where you need to be and what it takes to split that gasket. DAMHIK.

Also, keep track of which bolts come out of which holes. They are not all the same length. The FSM has a diagram of which goes where if you happen to lose track of them.

PS, if anyone has the hose from the smog pump to air cleaner, I'm in need! Thanks!
Sounds like you are on the right track. You will be happy when you are no longer leaking oil from the front.
