1999 996 VarioCam Concern

Engine

Vehicle Information: Model: 911; Year: 1999; Body Type: Coupe; Total Mileage: 87,000;

An independent shop told me last August that my 1999-996 C4 VarioCam assembly should be replaced soon. At that time Durametric reported the cam angle 1 at -8.89 degrees, cam angle 2 at -4.68. After approximately 4000+ miles the cam angle 1 is now -9.07 and cam angle 2 is -4.79. Reportedly once the angle is more than 9 degrees, failure probability increases, and the consequences can be major damages and likely require engine replacement. As the summer driving season approaches, I find myself reluctant to plan any trips in the P-car. Am I taking a chance in delaying the replacement of the parts involved (plastic guides?)? In addition to the cam work, I was told that it would be a good time to work on the clutch and RMS. Should I plan on anything else? What would a reasonable cost be for all this work?
