I recently got my 2018 1.5 Ecoblue Transit Connect back from repair at a Ford main dealer.
They took the camshaft out in an attempt to diagnose a misfire issue.
The camshaft was fine, so they reassembled and test drove it, and no misfires, so they told me to collect it.
I drove home and it seemed fine. The next time I drove it, an engine warning light came on.
I opened the bonnet and found oil pouring out of the engine all the way around the rocker cover seal.
Coolant reservoi also full of oil. There was silicon sealant visible where the rocker cover gasket should be.
They've had the van back for a week now, and told me today that Ford's official service procedure to use silicon sealant, not a gasket.
I don't believe them for a second. Can anybody here help me prove they're lying? Anybody have a workshop manual for this engine?
Or is this actually Ford's official repair procedure?
