Hello guys My car seems to have developed an odd metallic rattle. It only happens in 2nd, 3rd and 4th between 2k and 3k revs. Almost sounds diesel. Now I've not had the car long so it may be that I've only just noticed it. I've not long had the cam follower replaced, could it be linked? I have no loss of performance. If I rev the car from a standstill I get nothing? Its very odd. Also I can floor the car in 5th and 6th from any revs and it doesn't happen?
