Hi,
I have a noisy XUD diesel engine on my 205 - sounds like an old 8 valve fiesta, it's really clicky when you rev it. Firstly is this normal? And secondly if not, is it true that you can flush the engine with half-half cheap engine oil and paraffin and run for 15 minutes to solve it? Or should I just change the oil for some quality oil and have done with it. Cheers
