Rattle or clicking at higher RPM

I'm looking for a little help....

I did my best to search the forum, but I couldn't find anything that helps me with this.

I notice a rattle or possibly a clicking that starts when I pass 3k RPM. It immediately goes away when I drop below 3k. I have a manual tranny. It seems to happen in all gears.

I have 77k on my truck. The rattle/click started right after I changed my spark plugs. I followed the method posted on this forum that allows you to sneak out the plugs without having to remove the intake manifold.

Does anybody know if there is something that I could have done when I replaced the spark plugs that would cause the engine to be clicking? I'm hoping it's just a rattle that I will eventually find.

 

Remove any vacuum lines when changing out the plugs?

 

Yes, but they have been reconnected and clamped. I double checked.

 

engine cover on right? That will make noise if it’s not on properly

 

I was as careful as I could be, but I'm sure there's a chance that dirt could have got in. Is there something that you had in mind that could be clicking if dirt got in?

 

Yes, engine cover appears to be on properly.

 

Probably in your head?

 

V-tech kicking in yo?

 

Update.... the rattle / clicking kicks in when I am 3k+ RPM AND somewhere around half throttle or more. If I back off the throttle the click/rattle goes away, even if I am over 3k RPM.

Any ideas?

 

No clue man, i wish i could help. Any way of taking a video so we can hear it?

 

Could be pre-ignition....or...it's a resonance vibration from something at that rpm.
If it's caused by resonance, it could be anything.

 

I have the same noise sounds like it's a manual issue. I'm starting to think it's the spring clock behind the steering wheel. It's similar to an ABS noise but much more quiet. Any luck?

 

I seem to be having the same issue, have been experiencing intermittently for a few months now. 3k rpms and above seems to be the sweet spot.

I was hoping it was an ignition issue so I changed my plugs for the second time at 125k miles but still present after the swap.

V6 Auto, so doesn't seem to be only a manual trans issue.

OP, are you still around?!

 

Hey guys I’m another auto here with the same problem. I have a 03 pre runner at 297k it’s a one owner and always kept up on. As far as I remember it just started happening. At 3k she starts ringing and stops when you stop accelerating. Any info found yet?
