Hallo,

i am having this noise since i got my ride , didn't notice it much until I heard other CA18 running very quietly.

it 's kind of metallic sound , sounds like something hitting on th cam cover or some thing like that.

Any one experinece that before .care to share how I can DIY , take off the cam cover to see the cams and the belts to see what's causing the sound.

thanks a millions:help :help :help

Probably needs the valves adjusted. If it's got a black valve cover it has adjustable rockers. Silver has hydrolic unless someone changed the valve cover. Valve clearance is 0.012 hot or 0.008 int. and 0.009 exh. cold. If not sure when you remove the valve cover there will be a 12mm lock nut with a adjusting screw in the center on the rocker arm over the valve if they are adjustable valves.

hi,

thanks , found out the the timing belt tensioner bearing was loose and needs tighterning. now everything is well.
