Hi,
a few problems with the focus, not sure whether related. Have had to top up coolant twice within last month, with no visible signs of loss - then car started to 'miss' when accelerating, first under low revs but now throughout rev range.
Wondered whether missing was due to spark plugs, as had not been changed for a while, but when I removed the leads I noticed the first plug (to far left) was swimming in oil.
Could this cause the misfire? Wondered whether rocker cover gasket leak could be the cause (but have changed this 3 times within last 2 years...!)
Bit concerned whether coolant loss and misfire hint at head gasket failure, but there have been no signs of overheating to date.
Any advice welcomed.
Cheers.
