hey guys, was told by the Ford service ppl that i need to change valve cover gasket cause it's leaking. they found the problem while doing a regular service on saturday.

forgot to ask the guy there but i was wondering if this is covered by warranty? and if not, what's the price of the replacement?

so i'm looking to get a 2nd hand 1.0 ecoboost, do you guys have any recommendations or things that I should take note of when looking at the car ie which manufacturing year to avoid, wear and tear, mileage etc

seeing in carlist.my that the prices is around 50k+
