About 3 or 4 of my spark plugs seem to foul just at about 1 month for the past 3 months, I can tell when they go because it will stutter like crazy and have no power. When I pull them to check, I noticed they are covered in oil. Where do you think this oil is coming from and how to fix it? Its not the valve seals is it?

valve seals' is the most common resone for this, but ring's can be at falt also. if you have a little blue smoke at start up but that is it most likely valve seal's. if you have blue smoke while running, most pronounced while coasting down after a run, IE like on a freeway off ramp.

Make sure your engin is runing at the right temp. Or try some hot spark plugs. Also make sure your not runing with to much oil.

Change the valve seals...that's cheap to do. Also be sure it's not over filled with oil like the other post said. Someone had a chrome oil pan in my car when I got it, and the dip stick wasn't the proper one, so it always showed low, when in reality it was full.

If fresh valve seals dont fix it, then get some of them spark plug anti-foulers from your local parts'll go farther between foulings...this will help get you by until you can get the engine rebuilt. How do I know this? My first vehicle ('69 chevy truck) had a totally worn out 307...burned a quart of oil every 65 miles...a real mosquito killer. Turned out the rings were frozen to the pistons.
