As a side note to possible failures... If you have the 'marbles in a coffee can rattle' at start up the problem is the plastic pulley that the cable attached to inside the IMRC. See pic #9. The shaft that turns the pulley can strip the engagement pin on the pulley. If you open up your IMRC and have plastic shavings the pulley is toast and unrepairable. In my case this failure was caused by a faulty DSI manifold. The runner that rotates inside the manifold was beginning to 'sag' from the pivot points wearing and the runner was catching/binding causing the pulley in the IMRC to fail. I suspect the runners catching and binding is the actual cause of the broken DSI clip that so many experience.
