Update 2. Just had a phone call from the dealer.
1. They could not fault the car.
2. The tapping noise is the normal noise from the injectors.
3. The Oil leak picture above, is just sweating. They have torqued up the bolts on the cam cover.
4. I spoke to them about a knocking noise coming from the foot well of drivers side. (when the car is cold and you lift of the accelerator in 2nd / 3rd gear) Nope could not see anything wrong with it.
5. Did not even mention the spark plugs and the oil that the car went in for in the first place!
I asked the person I spoke to on the phone, if i could hear another 197 / 200 they have in their forecourt. Hopefully i will have time to do that this evening.
Failing that could someone post up a vid of their standard 197 / 200 engine sound?
