G1 engine noise

[stephens]

Took my '95 Lightning into the shop last week. They said it had a leaky water pump and timing belt cover. I had them replace the waterpump and timing belt cover gasket, chain & gear (123kmiles). Ever since then, as I'm driving and maintaining a speed the engines rattles (sounds like lifters). Once I give it the gas the noise goes away. At idle it sounds fine, but warmed up and lightly reving engine sounds like its coming apart.
This is a highway driver and never made this noise before.
Is this telling me its time for a rebuild?
Oil pressure guage is normal.
Performance seems unchanged.
No tailpipe smoke.
Truck is stock.
HELP!!!!!!!!!!!

I would be suspect to a damaged harmonic balancer. They might of damaged it while removing or installing it to the crank snout.
Good luck,
Steve
