I have 2001 C2 cab. Have a mag drain plug. Just changed oil after 5k and had 2 small bits of metal on it. Is the IMS about to fail? Can the car be driven 250 miles over mountains to the nearest dealer? Have a closer option on flat land. AJRS who specializes on air cooled P cars. He didn't sound like he likes the newer cars much and I'm not sure if he has done a IMS retro fit before. What should I do
