Gentlemen,
I have a 1972 SeaRay SRV200 with Ford 302 engine that smokes profusely. I
checked compression. It is 120 acrosss all 8 cylinders. I replaced the
valve stem seals. Still smokes bad. Can all 8 cylinder's oil rings be worn
out, which the compression rings are good, or is the oil coming from
somewhere else, like the valve guide being worn in the heads, etc? I'd hate
to pull the whole engine if I can get away with something faster and
cheaper. Thanks for any ideas.

The ol faithful approach to chosing beween valves and piston rings is
with a spoon of oil through the plug hole to look for a
compression pressure rise due to sealing the rings (temporarily)

The 120 looks high, but maybe it will go higher?
