I was lucky enough to find an ‘11 that had full oil change records completed at every 5k. It’s my understanding that this reduces the likelihood of chain tensioner issues. I know follow a 7500k full synthetic oil change regimen (Mobil Extended Performance) that meets the LR / Ford spec. Pre purchase inspection and exceptional maintenance records are a must. No matter what year.
ThanksOil changes every 5-7500 miles helps mitigage most of the issues, but I think there's still an aluminum piece somewhere on the tensioner that prematurely wears compared to the steel components used in the upgraded parts. I do believe you can hear when that aluminum piece is worn because that effectively allows the chain to "slap" and make noise because the aluminim piece is too worn to keep the proper tension.
Thanks. I have all the dealer records and wanted to have as much info as I could before selling it.I was lucky enough to find an ‘11 that had full oil change records completed at every 5k.

I have kept up with dealer service and have 119k miles with zero issues. Would it seem reasonable that I have the redesigned timing chains and tensioners in the '13? Does anyone have an estimate of how many more miles that engine would go?
