My Camshaft Deviation Numbers
 

Camshaft Deviation #1: -7.02
Camshaft Deviation #2: -8.36

Read from a Durametric with the car at proper temperature (driven for 20 min+ prior). Car is a 2000S, running fine with no codes. Based on what I have read from searching the variocam pads need replaced. My question is can I expect to see the deviation come down within spec of +/-6 with just the pad change or could there be other things at play here?

How many miles on the motor? And do you know if the IMSB is the original?

76k on the motor. IMSB was changed by the previous owner at around 70k.

Sure thing, such as chain tensioners. I wouldn't redline the engine until you get this sorted out.

Just sayin'............

Worn variocam chain rails

Replace both the variocam wear pads and the 4th and 5th timing chains. I had a 2000S with cam deviations of 7.xx and 5.xx. The wear pads were extremely worn on both banks. The cam deviations are now in the 2's.

Pad change: parts don't cost much, but it's labour intensive. You can DIY if you are brave. I did mine when one was at 8 or nine. You need the cam lock tools ( I made mine).
