Piston is out and these are the results, yet to take all 4 out but it was cylinder 3 low on compression so just took that out for now. Luckily no scratches or marks in the cylinder bore so just ordering devil development spec forged internals which are Mahle Pistons, BW Rods, ARP head stud kit, Deck brace, New Genuine Sump with baffle kit, King Racing big end bearings and a Ford head gasket. As long as I don’t find anything next week when I take the others out and have a good look in all the nooks and crannies that should be it.
