Hi thanks for getting back.
I removed the tensioner and that was clean and working correctly but did refit 1 clock further out however.
The previous owner was changing the oil ever 1000miles.
Last change 51miles ago, level is correct and clean.
I shall check the headers, however its not a exhaust noise. But will check.
Exhaust fully checked on ok tight.
Its booked in for the valves to be checked and new shims if need be in 2 weeks. But was hoping it was something simply.
