I am considering a 2012 platinum ecoboost with 171,000 on the clock. It is a clean 1 owner truck with complete records of all service completed at the dealership. The owner just let the dealer perform the recommended service intervals. It is a salesman's work rig with mostly highway miles(hahaha obviously). I know that the ecoboost hasn't been around that long and am wondering what everyones thoughts are?
1. longevity?
2. durability?
3. things to look out for on a truck with this many miles?
4. common problems with the ecoboost?
5. is this too many miles for this engine?

P.S. the seller stated that someone else looked at the truck and told him that it may need timing chains. He told me if I wanted to take it, get it checked out I could. If it was a problem then he would cover the cost of repair.
6. what model years is this a problem, how big is the repair, how do I check for it?

thanks in advance guys.

Timing chain issues are normally discovered by owners because of cold startup rattle in the engine. The engine needs to be cold like having sat overnight so the tensioners have bleed down. Other symptoms include timing jumping around, reduced power, and reduced MPG if you believe all the reports posted over the years.

I think you could call a ford service department and get a cost for timing chain, guides, tensioner, and phaser parts and installation. I'm sure it is in the thousands of dollars (2? 3?) as most things at the dealer are.
