Unexpected problem after repair
 

97' Honda Accord LX, 4cyl.... I just had my timing belt, water pump,
value cover gasket and other major belts replaced at 170K (sec belt) by
a local Honda dealer. The dealer also recommended having my spark plug
wires be replaced because oil had been getting them soaked. Now when I
drive the car, I hear chatter noise from the valve cover area. I've
never heard this noise before. I assumed the noise is coming from the
engine values. I also checked the oil level and it looked ok. I've only
owned this vehicle for 4 months and never had a problem. Could
something have gone wrong with my repair? Any help is greatly
appreciated
