I think I finally found what was the problem with my engine. I eariler reported that I had a knocking in the engine under the #1 piston cylinder. After finding out that I unplugged the the spark plug wire, the noise went away.
We finally took out all the spark plugs and did the pressure test. Below are the results.
#1 - 100 (then added WD40, took the pressure to 143) Spark Plug ends where heavey oilly sutted
#3 - 145 Spark PLug was Black
#5 - 148 Spark Plug was ok.
#7 - 140 Spark plug was ok.
#2 - 140 Spark plug was Black.
#4 - 140 Spark plug was ok.
#6 - 148 Spark plug was ok.
#8 - 140 Spark Plug was ok.

I am planing on taking the engine out of the car and tearing it down. Clean and degreasing it all. I am planing on replacing ALL the Piston Rings, All the Rod Bearings, and the Main Bearings. Then, finally, get a full gasket kit to finish it up.

Could you please advise, to making sure I am on the correct path. Thanks again!!!

I don't recommend simply re-ringing the engine. If you're tearing it down anyway, send the block to a machine shop to have it cleaned, checked, bored (if necessary), and honed. You can still tear it down and put it together yourself (which I highly recommend), but you're going to be very unhappy if you put it all back together and you still can't get the rings to seal because the bores are out of round.

Keep in mind, if the block needs to be bored (which is likely), you'll need new pistons. It wouldn't be a bad idea as well to send the crank to the machine shop to have it checked, machined if necessary, and polished.

Somethign as major as an engine rebuild isn't something you want to do twice. Do it right the first time.
