    Anyone see the latest episode of Wheeler Dealers, with the Porsche 997, it suffers with ‘bore score’, when they took it apart it was an open deck block. Not to scare people again but what causes this and could the RS engine suffer with this later in it’s high mile life?

    Watched it last night. Shocking from Porsche to make an engine that suffers like that. Sure they said it was down to the piston moving/slapping about inside the cylinder. Glad I didn’t have to pay for the repair on that!

    No idea on the Ford front though

    Loads of stuff on the web about it but interestingly enough – (copied from google)

    the sixth cylinder becoming hotter when thermal and mechanical stresses were applied across the two banks of cylinders. This in turn causes the sixth cylinder to become slightly oval in shape, causing more friction between the cylinder and the wall which results in the cylinder lining being rubbed away. Once the protective cylinder lining is damaged, the cylinder is in direct contact will the wall which causes scarring…..

    6th cylinder, cylinder protective coating wearing away – perhaps we’ve escaped this one – but all cylinders can be scored in some way shape or form or explosion / breakage. That’s my thoughts.

    Time will tell, although there are a few on here with decent mileage.

    @coastliner: 154000 km/96000 mls to be exact. No idea about the cylinders, though, but it pulls like a train every morning 😆

    Brilliant it was you I had in mind so hopefully good for at least 200000kms or even miles.

    Anyone seen this week’s episode with the evo 7? Nice big hole in the side of the block. Looks very familiar…

    Don’t worry about open decked engines, the most thrashed high revving engine in the world is open decked and that is the ultra reliable Honda Civic 2ltr Type R engine.

    Even the Type R engine benefits from a deck brace lol
