I just finish put the water pump in yesterday got the vehicle all back together and started it to check for leaks and there was a "tinking" noise coming from the valve covers its not a knock or a ping but a tink. Somebody told me it sounded like the rocker arms were loose. What else could it be, if it is the rocker arms should I tighten them or replace them as well? thanx

 

What motor?

 

Might bethe lifters, mine tink sometimes.

 

Oh sorry 3.0 V6. And I just finished putting the valve covers back on after checking the hydrulic lash adjusters and tighting the the rocker arm bolts and the noise(ticking, tinking w/e) is gone. thanx for the input
