smoke out of tail pipe

I hope that's all it is! Run it like you stole it!

Now, after the drive ( while warm ) check the plugs and see if they cleared. If not, change plugs ( or clean ) and drive and check plugs for soot. Hopefully, it will clear itself on just being warmed up. When restarted after a cool-down does it smoke?

On restart after a cool-down (restart it the next day), it still has the whiteish smoke when engine is revved up even after warming up (warm up in the driveway). If I go out and drive it, the smoke goes away and exhaust is clear. After driving a short driving distance (~5 miles) and then sit the car in the drive way and rev the engine, exhaust is clear.
 
Warming up in the driveway isn't a great idea. I know lots of people do it, and some here may well disagree with me, but if you're going to warm up an engine, like you do sometimes before a race or what-have-you, then warm it up at reasonably high revs, like 2,500 plus - too high for the neighbours possibly.
If you warm up at idle speed you'll get condensation from combustion in your exhaust, as well as incomplete combustion in your cylinders and consequent risk of contamination of your lubricant.

I suspect the "smoke" you see when you rev up after warm-up is the condensate in your exhaust system being driven out as steam.
 
What is the air temperature and humidity in Oregon at this time? Have you checked the plugs to see if they are clearing up? A 5 minute drive is not good for a warm-up. Car needs to be at running temp to clear out excess moisture. I'd still like to know about the plugs though. There is an old trick to letting excess moisture out of mufflers I learned and use sparingly.

What is your old trick you talk about?

It's cool and damp, but my Frogeye doesn't do that here in Portland. Very odd.
 
It requires drilling a hole of a certain size in the muffler at a certain spot. Never refer it, as I would not do it on a mild steel unit, with a possibility of staining a concrete drive or garage floor. We used to do it years ago on new installations on rarely driven vehicles to help lengthen the life span of the muffler and resonators.
