The high pressure oil pump is driven off the cam gear, there is NO cycling to it...there is NOTHING to tear up. There is an A/C pressure cut off switch that STOPS the compressor from running when pressures reach high levels to prevent any damage. There is also a pressure relief valve on the A/C manifold that will release excessive pressures if they would get to high from a failed cut off switch. I have never seen a crankshaft sensor fail yet...except for one that I damaged myself. (yes, I do make mistakes) Thank you for the congrats on my 13 years, but that wasn't my intent. My intent is to caution other users of some of the "repair procedures" you have stated.
