I have been having a ticking noise from the engine that seems to parallel the rpm of the engine. it only becomes noticeable when slowing down for a turn or stopping. I have checked manifold for cracks adjusted valves and all new injectors. Hold down clamps are tight... Any other suggestions before I take it to the Mechanic to double check valve lash and diagnose the ticking? 

Cracked exhaust manifold maybe? Bad front u joint?

As stated I checked the exhaust manifold for cracks. What would other u joint symptoms be?

Did the ticking noise start before or after adjusting the valves and doing injectors.

If you're planning on keeping your truck and having money I would forget about that word (mechanic) if you're capable of changing injectors and adjusting valves I think you can handle quite a bit more with right tools and patience.

Plan to keep the truck forever. I'm definatly not afraid to do anything as I even plan to rebuild the engine when the time comes. It was all before the valves and injectors. Its been going on for 3 months now and I cant find the problem which is why I suggested a mechanic LOL. 

It seems like the sound is coming from the engine but I  cant verify that. It is not possible to hear it at idle only when in gear shifting down to a stop. 

Does it follow the engine rpm or wheel rpm?

Its hard tell but I'm pretty sure its engine rpm...

Perhaps the A/C compressor clutch kicking on/off if heat control is left on defrost?

Its a fast ticking not a slow ticking. 

Bad idler pulley? Also wondering about something caught in the rear drums perhaps. Try slowing with it in neutral with brakes only might help detect something.

Thanks I’ll try that. 

I once had a buddy walking along side my truck while idling up to his shop. He kept hearing a ticking sound and it turned out to be that I had a slightly bent inside dust cover to the front brakes that was rubbing on the wheel.

That could very well be my problem... I’ll check these things and see what I come up with.

I def need to check again but seems like I never hear it unless truck is in gear....

I had a cracked rotor n my Pstroke one time that ticked every time it went through the pads. Just a thought............

What are a few symptoms of a bad idler pulley? I am writing a list of things to check so I don't forget and thought I might as well see what tht might have to do with it while I'm working on her. 

Ticking noise, Screech, screech noise, belt running crooked are a few things that come to mind. I'd pull the belt and feel for tightness or sloppiness. Do a typical bad bearing check in other words.

Thanks I’ll do that.

If I could add to this, if you can’t find the noise, what makes you think a mechanic will? Most mechanics won’t give it much time, if the trucks running right, it’s fine. Unless it’s blatantly loud, turns it’s likely obvious what it is. 

 

Just saying, being a mechanic doesn’t means they can fix everything.

I actually have a very good friend that’s a quality mechnic. I stopped by one day just to see him and we somehow got talking about it. He got out this tool that looked like a stethoscope and probed around and he thinks there is excessive noise coming from the tensioner arm....
