I do see some blue smoke when I get on it hard, but I attribute some of that
to boost. This smoke is not very easy to see during the day, but it is a bit
more evident at night with headlights behind me. There are no spots on the
floor, but you comments about leaked oil burning before it hits the ground
warrants some investigation.
Plugs and wires get changed every year, so the ones on there are no more
than a year old. I will change again just because it is easy and cheap.
A leak down test is in the works.
Thanks for your input.

Not too bad, but the lower #4 numbers and the plug buildup might point
to a problem.
Depending on your definition of "a lot of oil", you may have other
problems, too.
If a lot of oil is being burned, then you will have blue exhaust
smoke. If it is leaking out then you will probably have puddles of
oil. Mine leaks a little from the valve cover directly over the
exhaust header so I don't get puddles but I do get a little burnt oil
smell.
The clumpy buildup might be caused by a bad ignition wire or bad plug.
A leakdown test is probably in order. That will give you more clues
as to what is going on. Oil problems are usually valve stem seals or
rings. Good luck.
Cheers,
Derf
