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?
NB 375, Goodrich hoses, RDU cooler (fitted for the hell of it), gas bonnet struts, Mountune RR, hard pipe kit, V1 cat-back….and RS seat covers!
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
Collins Cp2 map. Ramair induction. Mountune mud flaps. Scorpion Sports Cat. Scorpion Tracker. Wind deflectors. NB washer jets and shark fin aerial. EBC Grooved discs, YellowStuff pads. Airtec Intercooler, Miltek cat back with titanium tips. Collins quickshift. DSC Controller
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.
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
