M62 ticking noise
Hi all, bit of a sad first post. My M62TU equipped X5 4.4 has developed a ticking noise. I checked the spark plugs they where all tight.
Engine is at the mechanic now, curiously when he revved it the the ticking noise stayed at the exact same frequency as when it's at idle.
Mechanic believes it could be the oil pump (chain?).
I was thinking maybe the dreaded timing chain guides myself, but surely the frequency would increase when the engine is revved.
Worst is my warranty ran out just 2 months ago.
I used the mechanic before but surely it's always good to maybe have another opinion.
