1996 993 secondary air


Vehicle Information: Model: Carrera 993; Year: 1996; Body Type: Coupe; Total Mileage: 60,000;

I have been adding a half quart of oil to my 993 about every 500 miles. I add it when the oil level dash gauge starts to stay just in the red zone with a warm engine, on level ground, at idle. It seems that the CEL comes on, code P0410 (clogged secondary air injector), after the next 10-15 mile highway trip. I bought an OBD II code reader to reset the light. My mechanic has checked it out, and the secondary air does not need service. Valve guides were replaced under warranty by original owner at approx 15K miles. Have you heard of other people having this problem coinciding with adding engine oil?
