My Zetec is doing my head in !!!
!!!!
I've lost count of how many times I've han it in and out again ( and Stripped right down) !!
On tick over and on partial throttle (parked up and under load ) it has a very slight miss-fire on no. (I think) 4 .
I've had the head off, lapped the valves, had a head specialist give it a visual check and given it the all clear(twice), I've changed the bottom end, fitted 2 new head gaskets in the process, done a compression test on all pots which are at about 130 PSI, swopped no. 1 and no. 4 Injectors around, and swopped no.1 and no.4's HT leads - Yet still I have a miss fire on No.4
The piston top looks slightly wet/shiny through the spark plug hole, and after sticking a cotton bud down there to take a sample it seems to smell more oily rather than of petrol, Yet it doesn't seem to be burning oil?
What could cause the oil to get on top of the piston ??
!!!! HELP !!!
