Thank you yes well I'm getting confused with what they've replaced and what they haven't. Apparantly this is the last thing to be replaced that has any bearing to oil leaking onto the pistons over night. Could they have bodged the valves, 2 engineers have looked at them and say all is ok and they don'tunderstand how the oil is still getting in. The car is still missing and is getting worse as is the smoke in the morning. I only took it in for a flaming service!
