Hi Folks, I cleaned my spark plugs and noticed all were ok except No.1 that was wet with oil. Engine has decent compression and runs smooth as silk. Car has been sitting for about six months. Could it be I have excess oil that has creeped into the cylinders due to a bad valve stem seal? If I rev it at idle it will smoke at 3000RPM and then clear up. I'm guessing I should drive it for awhile....any suggestions?

After sitting for six months I would drive it a while and check the plugs again.

A way to test valve stem seals is to coast down a long hill, foot off the throttle and then full throttle. That way the cylinders have high vacuum and suck the oil in through the valve stem seals. If you get a big puff of blue smoke thats an indication the valve stems are leaking oil.

PCV's can also be a source of oil. You can check the PCV hose to see if its wet with oil.
