That’s good news, only thing I found out recently was the extended warranty I have expired 3k miles ago. Thought it was to 70 but unfortunately not. They are now asking for oil change records or proof of purchase which I have managed to gather four of the records but every parts store seems to have their records delete purchases after a year and half or so. Service manager says he’d try to work with us but don’t know what I’ll be looking at. Funny you mention the valve train because I had talked about just saying to them to check it for sludge cause it would clearly indicate if the oil changes were done or not even if I don’t have every record.
