Annoying tick. Fuel injectors?

When I bought the car it came with this annoying tick. The guy I bought it from said it was a bad lifter. But I've changed out all 16 and it still has the annoying tick. So after a little research I discovered it could possibly be the timing chain, so again I take off the cover and check...the chain wasn't lose nor broken, the teeth were all there and in tact. I bought a stethoscope yesterday and took a listen all throughout the motor and transmission and discovered it's coming from the fuel injectors. I removed them one at a time and then checked them all again and I'm pretty sure it's every single one of them. Note that when I bought the car it had been just sitting in the guy's yard for a while. My question is if I clean the injectors will that solve my issue?

It's pretty loud...and obvious. It'll make you think something is about to go out. Although it's most likely not. It runs just fine, no sputter or anything so it's getting enough fuel. I assume they're just clogged since it's all of them and not just one or two. I haven't priced injectors but I've heard they can get expensive especially if you're replacing all of them.

I listened with the stethoscope and that's where the noise is coming from. When you remove one (while running) it gets a little better and not as loud. When I adjust the idle to lower rpm's to around 700 to 800 the noise stops completely. I can't leave it like that though otherwise the car won't stay running unless my foot is on the gas. I do need a new IAC valve.

As far as miles on the car? Haven't the slightest. The odometer stopped working at 108,000 miles.

Yeah. I think it sounds worse than it actually is. I'm not sure what else it could be if it's not the injectors though. I'm all ears for new suggestions.

Sounds like a piston slap or a rod:/ but I can't hear on my phone very good the speakers suck. So I could be wrong.

Idk about that. That'd be more of a slap and a knock than a tick. Valve maybe? I'm certainly no expert on mechanical engineering by any means. That's why I'm asking you guys haha.

Did you check for exhaust leaks at the manifold gaskets?

Didn't check that. I know it has an exhaust leak on the down pipe but you can tell this noise is coming from under the hood not under the car. But if it was an exhaust leak why would the injectors be making the ticks? When I place the stethoscope on the block itself you can't hear it, only on the injectors.

I just changed the oil not even 2 weeks ago, all new filters, plugs, the whole nine yards. Synthetic oil. We've tried 5w20 and 10w30 and it does it with both weights. Right now it's running the 5w20 because I'm afraid the injectors are heavily clogged with build up. Maybe I'll try cleaning all 8 of them completely and drain out the 5w20 and replace it with the higher weight to see if it makes a difference. He's got a lot of gunk running through his veins that I'm still trying to get cleaned out.

The injectors are solenoids that are constantly opening and closing.
They tick.
Some are louder than others.
Get that exhaust system "tidied up". It's bad if I can hear an exhaust leak in the video...

I'm hoping that's all it is. A leaky exhaust is still cheaper than forking out $400-600 for a set of injectors.

You can have yours cleaned and tested for around $120 if you think that may be the problem. Repairing the exhaust will help a lot though.

I'd rather do it myself. I'm pretty picky about who touches anything that goes in, on, or around my Grimace haha. My boyfriend thinks I'm nuts. But it's just a thing. I have no intentions on racing him or "showing off" like most of you men do. It's all for the bond of the car. I've done quite a bit already (things that my boyfriend said were impossible for a girl my size) but I managed. I think clean fuel injectors would be a lot easier than the things I've already done lol

Unless you have the machine that cleans them ultrasonically while simultaneousally opening and closing the injector, and the equipment to flow test them, and a source for the tiny little filter that is inside of the injector and should be replaced... That is going to be EXTREMELY difficult...

I have a guy for that. He's been restoring cars for decades. He has everything I could possibly ever need.

I ran seafoam through him when I first got him. I don't think it's strong enough. I need something a little more heavy duty.

Checked the exhaust manifold today. This morning while it was still cool out I put some soapy water around it and started the car and didn't notice any bubbles so I don't think it's an exhaust leak. Everyone I've talked to around here says it's the lifters but like I said I replaced all 16, and I've even gone back and checked to make sure none of them were damaged or flattened anywhere. They're all clean. I've googled it so many times but people are saying this is normal. But this tick is quite loud as you can tell in the video, am I missing something? I know someone mentioned a rod but the noise isn't coming from the block. Can the injectors really be that loud?
