Thanks all,

I guess what I'm looking for is some kind of guidance on replacement. I messaged Autodata to see if they had any 'known fixes' and the guy said that the problems were on the replacement belts and not the original fit..??

I only have a couple of customers with the Puretech engine and in the last few months, we've just started to see some Ecoboost Fords for servicing.

I know some of the Ford diesels had a random choice` of belt or chain (and the dealer couldn't tell what was fitted) but I've never known an issue with either.

So, are you folks just changing them earlier, or do you wait for things to start clogging up - which is surely too late? Anything to look for in the oil or filter when they're being serviced?

FWIW, we've never used any oil additives. I remember when Wynns were paying for Gold Seal boxes on Austin 1100s & 1300s when our local dealer added it by default.

TIA
Dick
