1999 Boxster Camshaft Deviation Repair

[CRNile]

I sold my 1999 Boxster out-of-state to a guy in Ohio. Well when the car was analyzed by two Porsche shops, they both found a cam shaft deviation of 4 in Bank 1 and 14 in Bank 2. They told him not to drive it.

When he got the car repaired, they replaced two timing chain tensioners and stabilizer link. In addition they replaced the IMS bearing, clutch, spark plugs, front sway bars, and brake fluid.

The IMS bearing replacement was ~ $2000 and the total $4,000. Now the buyer is asking me to consider paying him $1,500 to help cover the unexpected costs.

I went to my garage with the invoice. The owner of the garage is also a 1999 Boxster owner with about twice the mileage. He had just performed my annual service in February and said it was nearly perfect. He also told me that the 1999 Boxster seldom had an IMS problem. It was 2000 models and after. He also saw no evidence of filings in the oil filter or any error codes.

Any thoughts about whether this person was taken?
