clicking noise when car's running and at idle

[Howard Hu]

this clicking noise under my hood.sounds like its coming fromt he timing belt..but not sure..clicks faster if i rev up more..any ideas?

[Travis Merrick]

lifter tick, but u have a 2g right? does it go away? we need some more info, did you do an oil change or did it just start to happen, there are many clicking noises in his world, and that description doesnt help us to help you trouble shoot.

Yah dude, same thing happens here.  Usually just while it warms up, then after a few seconds it goes away...  my car is a mystery though.  So I do not know, all I know is I did compression / leakdown & had no problems.  So could possibly just be noisy lifters or diry valves.  Solution to dirty valves is as follows, I have not dared to try yet hehe, maybe you will.  If your doing an oil change soon.  Might get rid of ure noise.  Frankly I love it, .

usually 2g lifters are pretty good, but possibly only on cold starts, what oil u run? i could see it being more predominate (sp?) if you are running a synthtic based oil as regular dino oil is alot thicker and sticks better in the lifters.  When I first start up my car when cold, well the lifter noise is quite...   irritating you could say, but goes away after 5 minutes and will sometimes re-occur while driving.

Get someone to press in the clutch and see if the ticking goes away, if the ticking goes away when the clutch is depressed you may be in for a very bad day, as this is an indication that you have Crank Walk.
If that is the case you have to go and get a more specialized diagnosis made.

yah cold starts it clicks..and sometimes it goes away..but sometimes it keeps going

[Alex Nazar]

Mine clicks all the time...the worst is when im at a red light and the person in the car next to me can hear it...with his widows UP! It's so embarassing  :oops:

I heard even if you clean them and do all that work, its just a quick fix and comes back in like 6 months. Is that true?

[Chris Clark]

If you can hear it specifically from the timing belt area, it could be the hydraulic tensioner.

[Howard Hu]

its aroudn timing belt area

[Milad Lari]

its ur lifters...my car does it for the first like 45sec to a minute when i turn it on first thing in the morning then it goes away...i dont think its doing any harm to ur engine...jus ur lifters...am i right?

[Howard Hu]

hmm i think so
sometimes it stays on the whole time im driving
its just annoying lol

I have a 1gb, and mine does it too, for about 10seconds on a cold start, it sounds horrible, lifters ticking and the belt squeaking somewhere sounds like all hell for about 3 seconds.

[Eric McIntyre]

the belt squealing is pobably the alternator belt....just tighten it a bit.
mine was doin it hardcore in the cold so i just tightened it a few turns and it was gone.....as for lifter tick.....well whatever not much i can do about that

[Leon Hui]

I thought if it ticks when you press down the clutch pedal that's a sign of crankwalk...?

That's correct.
