my car use to make a small pinging/clicking noise when going u a hill in a high gear, pretty much when ever the engine was under pressure and couldnt pull so well, i have just replaced the timing belt suspecting that was the problem and because the timing belt was due and it still makes the pinging noice maybe not so bad but still noticeable. any ideas anyone? anyhelp would be appreciated

 

also i wasnt fully certain if i tensioned it fully right, i did the right procedure according to manual, and im using my original tensioner.
