pull the sparkplugs, set up a dial indicater on any intake/ exh retainer, turn the engine over by hand slowly and check total valve lift. compare that reading with the cam specs. a couple of thousance diference is normal wear, major differance usually means worn out lobe. if you plull the liters first (keeping them in order) a worn liter will tell what lobes to check. all the debris in the oil is not good for rod/main brgs. hope this helps...
