I have a 09 porsche cayenne turbo and every 250miles I been fouling out spark plug with carbon build up only in cylinder #5. I replaced spark plug, coil pack, fuel injector. I did a compression test it was strong. Also going thru 1 quart of oil every 250 miles. Has anyone ever had this problem not sure what else to check.

I have only put 4000miles on the car it had 111k when I purchased it. I have also checked the oil separator that looked in perfect condition. So i running about 3000 miles from when I found out about the problem.
