Reply to "Exhaust Smoke"

Well it took me awhile but I finally got around to doing a leakdown test on my engine. You guys were right, it is indicating a problem. Listed below are the cylinders in the order we tested them, followed by the percent of pressure they held:

#3--96%
#7--93%
#2--98%
#6--98%
#5--87% Heard air thru carb
#4--18% Heard air thru carb
#8--96%
#1--98%

So, it looks to me like I've got a couple of intake valves that are not sealing or closing. Any ideas as to why this may be happening? I have a call into Russ Fulp but I would like to hear what you guys think. I could hear a very slight amount of air passing when I stuck my ear into the tailpipe. I assume this is normal? Could this problem with the intake valves account for my excessive oil consumption of less than 300 miles on a quart? One encouraging thing is that I think I have found some of my missing horsepower. I'm looking forward to your responses.
Thanks,
Art
