Another way to look for oil from the exhaust is to run your fingers over the
bumper above the tail pipe. If there's an oily film on the bumper - you can
guess where it's coming from. Low compression will tell you if it's rings
or bad valves. If the compression or leak down are good and you're still
burning oil, its likely to be valve seals. A quick check for ring problems
is to look for blow by - oil in the air filter coming from the crankcase
vent tube. Oil will pool along the bottom edge of the out side of the air
filter - on a stock one anyway.
By the exhaust seeming strong, I'm assuming you mean it's smell. Likely
your mixture is rich. Check for that - black soot on the plugs after a
drive - they may get a bit sooty after idling for an extended time even if
the carbs are adjusted correctly. Better to be to rich than too lean
although rich won't due worn rings any good as it washes the cylinder walls
of their oil and shortens ring life.

1. I finished my Gary Boone distributor install. today I finally installed a
proper coil. car crank rights up without a hitch. im still getting smoke
however. I asked my wife what color she thought it was and she said bluish.
so it must be oil. I placed a paper towel at the tail pipe but it did not
get anything on it so im not sure. I held it there for about 20 seconds or
so. is there a way to tell if the oil is seeping through the valve stem
seals or if it is worn rings? would that be a compression check? if so what
numbers should I be looking for? the car exhaust seems very strong as well.
the blue smoke does not poor out. it puffs out. the faster the engine runs
the more it puts out although it is not a cloud. the car can sit at idle and
nothing seems to come out as well.
