    Have you had a dynotune with the cam? They look burnt to me as well as well oiled. Also have you run any sea foam or something similar through your engine? It has been known to foul plugs.

    Car was tuned with these plugs also I have used seafoam in the oil gas and through the booster butbwith the tr6s it runs so much smoother , but honestly seeing that much oil scared me

    If your engine is burning oil, you will have telltale blue smoke coming out the exhaust. I can't really see the electrodes in the pic, but the coloration really doesn't look too bad. Did you clean around the plugs before removing them? Any external oil weepage from the rocker cover down into the plug wells? If so, the threads will come out with an oily look to them.

    FWIW, stop dumping Seafoam into your car. Once a year, use Chevron Techron Fuel System Cleaner and, if you insist on running something else, then do the TCW3 oil treatment at one (1) ounce per five (5) gallons of fuel as often as you would like.

    from what I can see they don't look that bad to me....electrodes look like a decent color from what I can tell and that's not enough oil to worry about.

    I agree, not a good pic of the porcelain but from what I can see the color looks fine. Just a heads up, going to the TR6 is a colder plug so if you are worried about oil or gas fouling the issue would actually be worse with the colder plug.

    Any oil entering the combustion chamber is a bad thing, and alot of that can be traced back to the horrible PCV design. I agree these engines all need catch cans, I'd invest in one if you don't have it already just as suggested. That would clean up some of what you are seeing.

    Would be hard to see any oil smoke out the tailpipes if you are still running cats (unless you have a very severe oil issue), because the cats burn up most everything before it exits the tailpipe, so mild smoke usually won't make it out the tailpipes.

    I also use the TCW3 2 cycle oil mixed in the gas just as Jeff suggested, 1 oz per 5 gallons for gas engines, and I mix 1 oz per 2 gallons for the diesel. Good cleaning and lube abilities at the same time. It's also cheap to do. $11 for a gallon at walmart will treat about 600 gallons at that gasoline mix ratio.

    Is your catch can... catching? Some designs are better than others. Maybe open up your throttle plate a take a look inside with a flashlight to see if things are oiled up.
