1G Ticking noise coming from intake

[BoostBolt]

Anyone have a video of what lifter tick sounds like? My car developed a tick. Not sure what it is. Here is a video of the noise Ticking video

I'm getting a intermittent ticking noise around my intake manifold on my 2.3l It sounds like it's coming from by the injectors or behind the timing belt cover. It only started about a week ago and comes and goes at idle. It doesn't sound bad it's just annoying.
It kind of sounds like if you were to take a card and put it in between bicycle spokes.
Any help would be vary appreciated. Here is a video of the noise Video

Sounds like a partially collapsed HLA
I'd take off the valve cover after it's been running for a little bit (but not before it gets too hot to handle) and see how much play you have in all of them. You might find you can depress one

Ok thanks. I did give that a try already but they all seemed tight. Maybe it's not failed enough to tell? It's not always ticking though. If you rev it up then let it idle. It ticks and then goes away kind of in random patterns, but that seems the most consistent. If I open the oil Cap I can't tell a difference in the sound

I'd agree it sounds like what you are hearing is an HLA.

When you remove the valve cover to inspect you also need to rotate the engine to different spots. If the collapsed lifter is compressed on a cam lobe you aren't going to feel any play. If you do find one that seems to be collapsed re-install the valve cover and run the engine again. Then pull it back off and check that one again making sure it isnt on a lobe. They will bleed down so this verifies the lifter is actually bad and not just bleeding down.

Its a huge pain to do all this. A lot of times it's just easier to get a new set of lifters.

Short of a collapsed HLA, inspect your timing belt tensioner.

Okay I'll give this a try I didn't think about them being on the lobe, but that makes sense. I also have an extra set of lifters laying around I could try. Thank you

I don't think it is, but I already have a new tensioner I'm planning on installing. Thanks
