I really don’t know where the rumours if revised engines, recalls and the wrong gaskets being fitted are coming from. Ford are totally tight lipped about this.
The one about the wrong gaskets being fitted sounds like fake news….great fake news for Ford though, implying nothing wrong with the engine, a simple mistake and nothing to see here.
Probably going to get shot down and called negative for daring to mention this but if say 5% are failing at 12 months old, will they get exponentially worse as the miles build? If so the cars will be worth jack at say 5 years old.
It seems the ST has dimensionally the same block….the RS just has a longer throw crank on it to get the extra capacity, why Ford went with the cheaper to make open block is beyond me.
The Mustang using a similar block has cooling slits machined between the bores…the RS seems to have a tiny water passage cross drilled. Maybe they were trying to stabilise the cylinders but the cross drilling is not providing enough cooling. Who knows.
I hope the detail changes if there have been any on the latest engines are enough to prevent failures, not just stave them off for 20 or 30 thousand miles.
Maybe not great going over old ground….but the more noise about this the more chance of a proper fix, if that is possible. The old Porsche 944 turbo engines were similar in bore and head interface design and failed as well….
