Have just been out with another golf head from work, Matt - GPES.
Have identified its definately top end, cam rattle, he reckons chain similar to previous thread.
Spot on about the rev range 3-4K fine either side of that. And about being able to listen to it, can't hear direct, but in the car the Oil pressure gauge feeds the niose straight through as its direct feed from the engine.
Matt has got a spare good head from when he ABF'd his valver so going to pop that on and hopefully rocberts your fathers brother!
Thanks everyone, proper helped.
