[QUOTE="SRAD97750, post: 227977, member: 425"] Bottom end knock can occur when bearings get worn out. But typically cause it to run poorly or not idle. What was the wrist pin to journal gap? Any detectable side to side play? A loose cam chain will sound like marbles in the engine, or metallic slapping. Typically will not cause any performance loss, but can be literally deafening. What was the measurement of the cam chain for 10 links as per the manual? In spec at the time of overhaul? When was the cam chain tensioner last replaced? Coolant dripping slowly from the case weep hole indicates water pump seals, usually needing a water pump rebuild kit. -BIG DAN:thumb: [/QUOTE]
