But at least the cam drive system as a whole can be evaluated externally by monitoring deviation(measured in degrees).
PS- we do offer the M7 bolt conversion service for workshops who don't have the machinery and the fixture.

Hmm maybe I should try checking this

When bolts are backing out, you'll hear all kinds of ruckus, CEL, low oil pressure warning...so no need to continue to run the engine to check the cam deviation. Should the engine continues to run the cam deviation would be maxed out due to zero oil pressure operating the flaps inside the actuator.

Lots of threads on the cam bolt issue. Wasn't sure where to post this question, so I just picked this thread instead of starting another.
Let me first say, I love this car. Only put on about 300 miles so far, but it's glorious. But the two issues that are forever on my mind are the coolant pipes and the cam actuator bolts. I try to be hypervigilant about any changes in the sounds from the transmission. While I know it makes quite a ruckus at idle with the clutch out, is it normal for it to still sound like a bag of marbles (albeit less so) with the clutch engaged and driving at low speed? I never noticed it before but heard it today while negotiating a parking lot. Just trying to stay ahead of any potential (catastrophic) problems.

Well, that's a mixed blessing, I guess. But I do recall one member here stating that he heard something not quite right with the normal rattle. Shut it down and fortunately saved himself from replacing the motor. Who knows if he actually heard something or just luck. I'd have to find the post.

Since I'm in the process of having my coolant pipes pinned on my 2011 RS, I will be checking the cam actuator bolts. Assuming they are in spec, would anyone recommend taking them out and putting thread locker on the bolt and retorque? If so, is the torque specs the same on both sides? TIA

Are you getting the lines pinned as a precautionary measure or did one of them let go?
