I just bought a 2000 gt that been sitting for 7 years. Long story. But anyway I just got it running good and everything legal and I herd what i assumes was a valve issue. Supposedly it had the timing chain done already but from what I’ve been reading about that noise it doesn’t seem to be that. I will say i have no power steering at idle and not moving. But can a bad power steering pump make a noise that would come on kinda like a rod knock but it’s more tap then knock

Maybe its your ac pump. That stops and makes that noise. Its caused by excessive use.

Old mechanics trick. Take an old wooden handle (hammer, axe, piece of a broom handle, whatever) and push it tightly up against the accessory component you think is the issue and put the other end to your ear. If there's a problem in there, you should hear it being translated through the handle.

If its engine related...could be a lot of things. Could be a little piston slap, could be rod knock, could be lifter (oil actuator) noise. Hard to diagnose over text on the internet. Why not shoot a video clip and post it up?

I can’t get the video to post but I thought it was a chian issue and even seen rub marks in timing cover. Got it opened up to see no wear on guides and tight Chan’s. Yet still put new parts on. Still makes noise. And being a mechanic it sucks. Does not make a peep till warm and only when no load on engine. Put 20/50 and a Lucas in still does it when hot. Plenty of others have the sound on internet yet no explanation. I do know it’s not a good sound and I’m gonna try and find the video and save the link and see if I can get u that
