2002 Boxster S fuel in oil

Fuel System

Vehicle Information: Model (Boxster, Boxster S,Cayman, Cayman S): Boxster S; Year: 2002; Engine (type, size, modifications): 3.2; Total Mileage: 77,000; Transmission: Manual;

Oil analysis shows 10% fuel in oil. Also secondary air injector in bank 1-3 malfunctioning, showing check engine light. I believe the two problems indicate leaking injector in that bank, carboning up the charge and clogging valve. Does this theory sound plausible? If correct, will flushing the injectors solve the problem, be a waste of money or would new injectors be the way to go. Maybe another solution would be best? I did buy this car and this check engine light came on 1000 miles after buying the car. I would like to know if my assessment is correct and will cleaning the injectors solve the secondary injector problem. After the first reading, I drove 3,000 miles and showed a 2.8% fuel in oil. I then ran about five bottles of Techron thru the engine at higher than normal concentrations. A check of the oil with an additional 4,000 on oil showed a 2.9% fuel in oil buildup. This I believe shows that I stopped the injector problem.
