I have a 2000 S with 66k with recent IMS upgrade. The car runs great and no codes. I recently bought a Durametric and ran the program to see if there was anything to be concerned about. Turns out that after a thorough warmup bank 1 is showing a cam deviation of 7.08. Bank 2 shows 5.33. At idle cam angles are 2.48 and .92 for banks 1 and 2 respectively. Running rpms up over 3000 results in cam angles of 22.16 and 23.67 for 1 and 2 respectively. I ran this by my local independent and he wasn't too concerned and suggested a wait and see approach since I had not found plastic shards in the oil (yet).
Based on all I have seen and read it looks like variocam tensioner pads. But I wonder if it might just be that bank 1 is and has been out of time. Is there any benefit to simply retiming the bank 1 cams, are tensioner pads a better diagnosis and is there any other likely explanation?
