    for what its worth, the way I read that is the "do not replace...." is specific to any repairs being conducted ahead of the TSB release... That would leave me to believe they could likely be included in the final TSB repairs if ford determines it is required.

    Just speculation of course. We'll know more when the TSB hits the streets.

    You actually don’t want to replace a relatively new timing chain with a new timing chain unless it’s stretched out of spec. Most of the chain ‘stretch’ occurs when the chain is new and can be disproportionate to the overall stretch over the life of the chain. In other words, the chain is going to stretch more in the first few thousand miles than it will over the rest of the life of the chain.

    If you have a vehicle with a timing chain that is in spec, replacing it is not needed, the chain will actually wear in a more predictable and linear progression than if you install a new one. But, if you’ve got a chain that is marginal or, has excessive stretch, you replace all the related components - sprockets, guides, chains because if you put a new chain on an abnormally worn sprocket, you end up with a chain and sprockets that wear abnormally fast. These things stretch and wear very similar to motorcycle drive chains.
