I can't figure out this noise. I have been researching it on the forums and I think it could be a spun bearing. I am getting my valves adjusted today just to be sure it's not that, what do you guys think?

its hard to tell but it could b ur tensioner. i noticed when my belt was old/ i guess stretched the tensioner would make a knocking sound at idle or if i lightly blipped the throttle.

 

I noticed that it got louder after my oil change. I switched to rotella t6

 

yea than its deff not what i was saying

 

I got my local honda to take a look at it and they seem to think that I need a valve adjustment

 

My car and many others do that, its cold piston slap. Does it go away when hot?

 

No it doesn't. That what has me worried.

 

Mine kind of does it to when its cold. After it warms up its nice and smooth.

 

Mine does this as well. It's not as loud as yours, but it's the same sound. Stops as soon as it's half warm. I believe it's piston slap as Billman said. I used to worry about it too until I found out how many others do it.

 

I can hear it when the car is hot but it's not as loud as it is when it's cold. I been sending my oil samples to black stone labs and they been telling me everything is good, so I think it's normal.
