97 c180
I have a intermittent sticky tappet,sometimes it clicks for a few seconds on start ,other times is starts quietly then clatters after a few minuits running. Sometimes this stops for no reason. I am fairly adept at mechanics having done my own engine/gearbox/axle repairs many years ago. Is there anything I can do without interfering with the timing etc? possible to undo cam bolts and tip up one end enough to get lifter out ?(I should be able to identify culprit) , try high detergent oil?, oil is clean but did run over milage before last change. Mobil 1 10/40 always used
