Ve Calais
Hi im having trouble with my calais , i purchased 2 years ago months later check engine light comes on a got this checked with scan tool and it read oil pressure sensor problem not long after the stability control fault sign pops on the dash with the engine running rough.scan tool showed misfire in 2 cylinders after inspection showed head gasket in cylinder 1 was gone so repaired all sparks plugs coil oil pressure sensor and head gasket drove fine for 6 months the whole thing started again. i now have the engine running rough with all the same signs again had checked misfire in cyl 1 and oil on sparkplug cyl1 leading them to think piston rings has anyone had any of these problems this car also has afm would this be a problem not wanting to get fixed then have the same issues again.

leaky valve stem seals can also cause oil on plugs
