Hi everyone.I posted a topic earlier in the month reguarding a loss of compression on my 1.8LX 51 plate Mondeo.The fault was indeed a burnt out valve.Had it replaced at a garage for considerably less than I was quoted from someone else,however,after picking car up,the eng man light was still on and the tickover was very lumpy.The car just didn't feel right.Took it back to garage where a fault reader pinpointed a misfire on number 4 cylinder,the same one as the burnt valve.A new set of leads & a new coil pack were put on but made no difference.Compression test was ok but the spark plug from number 4 was caked in oil (again).They now have the car back & are replacing the injector o rings.Does anybody think this will help or is another strip down required?They ruled out inlet manifold.Think this saga is going to drag on :angry:

oil leaks onto spark plugs are usually down to an ill fitting rocker cover gasket.

Er, was it the part of the spark plug inside the engine or outside?

if it was covered on the inside do you know if the valve stem oil seal was replaced when the valve work was done as a damaged seal will allow oil into the clynder.

I would like to think they replaced the seal.They still have the car because they've sent the ecu away to be re-mapped as they now think this is the cause of the misfire.When the car was started and reved prior to the removal of the ecu,there was clouds of white smoke billowing from the exhaust.They said it clears when you start driving.Never smoked before,at all.

Think it's gonna take more than fingers crossed Peter.Went to the garage where my Mondeo is in danger of taking root.Was told that the new,not repaired,therefore more expensive ecu,had been fitted but on starting the car there is now a misfire on number 1 cylinder.This saga is seriously testing my patience.The mechanic is now on holiday for the week,so wont be any progress for a while,not that there's been much so far anyway.Live and learn.

That'll be easier said than done mate.They're not the sort of people you want to argue with.I knew the bloke years ago and certainly wont be using him again.Might have to buy an old banger for a couple of hundred quid just to get me to and fro from work til it's sorted.Can't keep ponsing lifts and walking everywhere.
