So here's my problem. I've got a 2001 Boxster S with the factory 3.2L engine and ~70,000 miles. I bought the car in 2010 with 38,000 miles on it. I have it serviced regularly every 5,000 miles at the independent dealership, iAutohaus, where I bought it. They specialize in European luxury cars and I trust them as much as a person can trust a dealership, I guess. My wife drove out Monday from Phoenix to Albuquerque with no issues. After spending the night at a friend's house, she left to drive on to her final destination in Santa Fe. After leaving her friend's house, she called me saying the CEL was flashing and the car was running really rough and had very little power. She was close to an Autozone so I had her take it there to have the codes read. She called me back saying it read a P0303, P0302, P0301, P0300, P0304, P0305, and P0306. Which I know are misfire codes, on every cylinder. Well, while I was checking around to find a reputable Porsche mechanic in Albuquerque, I guess the Autozone salesman told her it was due to bad gas and to buy some fuel system cleaner and she'd be fine. I called her back to tell her what I had found mechanic wise, and she said she had driven it on to Santa Fe. She said it was fine as long as she stayed out of 6th gear and didn't rev the engine too much. I'm not real happy she did that. Anyway.... She got it to a mechanic in Santa Fe and he initially checked the coil packs. After clearing the error codes, he said the misfire on cylinder 3 kept coming back. He swapped the coil packs but the problem stayed with cylinder 3 so he began to think maybe spark plugs. That didn't help either. A compression test showed very low compression on cylinder 3 and a leak down test showed it wouldn't hold pressure. The mechanic is suspecting a broken valve spring, or worse, and is suggesting either a $4500 rebuild or find another engine. But of course, I'm in Phoenix and the car is in Santa Fe. Oh, and my wife, she is still there too. I guess I'm a little confused on how it can go from running fine one minute, to having misfires on every cylinder, to having no compression on cylinder 3. Although, I'm sure the fact that she drove it an extra 50 miles didn't help anything. I'll be leaving Sunday to go pick up the car, and my wife. I'm am an experienced mechanic, just not fluent in Porsche so I'm not sure if I want to tackle this myself or not. Do you have any suggestions on additional troubleshooting I could do or should I just start looking for a new engine?
