Hi,
I have got a 1998 M3 Evolution Coupe and wonder if you guys could shed some light on a little noise problem I have. I know that Euro-spec M3's are a bit different but maybe you can help.
My car makes a 'ticking' noise, that sounds like tappets. It is there shortly after starting up, as it warms up, and stays there no matter what RPM. It is very quiet at tickover however. There are no noticable power drops throughout the rev range.
I've heard mixed suggestions about it being a lifter, needing valve adjustment, needing shims to the dreaded double vanos problem. What do you think? The noise appears to be coming from the middle/rear of the engine on the throttle body side.
The car has done 87,000 miles and has full bmw service history.
regards,
Matt
