Join us on the Ford Owners Club stand at Ford Fair, Silverstone on Sunday 6th August 2017.
my fiesta st 55 plate 40000 miles has developed a tapping at the top end from 2000 rpm up, and was getting lazy to start (turning over about 5 seconds before firing. did a compression test and found pot 1 only had 8bar, 2 had 11bar, 3 and 4 both had 12 bar. removed head today expecting to find a hole in piston or a valve problem but all looks ok, waiting for head coming back from testing (vacuum and pressure and a skim), has anyone got any idea? did a sniff test before strippig all ok. head gasket looks ok cams are both ok, (will need a polish on caps) but no pitting or gouges just discolouring all followers look ok. next step is bottom end off but it was deffinitly a top end tap
