Re built top end and new headgasket last year and its done 15 miles since. Like a plonk I turned the inlet can 360 degrees and its now got a light tap - I must stress that its a light tap (not as loud as 'tappers' I have driven) and was not audiable from inside of the car.
Only done 70k
It pulled like a train and has no other issues. There are pics to the head rebuild if needed. £60 collected
