Hi everyone. I need to reseal the front cover on my 2016 gen 1 3.5L Ecoboost with 160k miles. I'm planning to replace the timing chain, tensioners, and other small parts while I'm in there. I'm not sure about the cam phasers though. It's not a gen 2 so there's no new part to upgrade to and gen 1 phasers were never a problem. I'm not having any particular problems with timing chain stretch, this is just preventative.
The only reasons why I'm considering replacing the phasers is 1) I'm already there and replacing things, and 2) when you run a stretched chain over a gear it can cause excessive wear on the gear teeth which can then cause additional wear on the new chain.
If there's no need to replace the phasers then I'll be happy to save the $700 and not do it, but I don't want to save money just to have it open again in 40k miles to replace the phasers. I'll have it open in a few more hours of work so I'll be able to assess the condition of the teeth then.
What's the common wisdom for the gen 1?
