Of the last 20 IMSR procedures we have done on 5 chain engines, 75% of the engines did not pass my pre-qualification due to excessive cam deviations that were created by these components being worn. We will not carry out an IMSR if cam deviations are in excess of 3 degrees, because the car will set a CEL after our work is done and then we have to explain that the issue was not a result of our work.
The 3 chain engine omitted these completely.

Jake, do you replace them with the superseded OEM part, or do you have a better replacement part?
