Could be as simple as injector noise that you're not used to (DI systems are loud). Could be valve adjustment, which is inexpensive.Hey guys,I'm fairly new to the forum. Please excuse my long post but I wanted to be as thorough and detailed as possible. My new SI that I drive about 45-50 miles a day is making me nervous because it has developed a rather louder than what may or may not be normal ticking sounds. Having a 2nd Gen Acura Integra for years, I knew this very well could be a Honda thing. It definitely goes away when the RPS are coming down. However During the first couple of weeks + the engine ticks were whisper quite. They were there but not very audible. During these first couple of weeks of owning the car I absolutely babied her to give her a smooth break in, up to about 650 miles. During this time I did absolutely NO launches, only revved to about 3500 RPM and I barley even hit boost, 1-3 IBS tops and if I saw boost was coming on I backed off right away.
At the end of the break in period I decided to ordered a Ktuner V2 to jazz her up a bit. For the next week after patiently completing the break in of 650 miles, I started to engage in some spirited driving and by No means " beating " . For the next 350 miles or so (still waiting for my Ktuner unit to arrive) I occasionally and moderately sped up from 1st-4th gear rolling my foot into the throttle maybe revving her out to 4500-5500( some WOT on the highway) but no redline no rev-limiter no tire cherpping and I still haven't launched the car to this day, (meaning dumping the clutch from like anything over 1000 RPM). SO Still up to this point(about 1000 miles) whisper quite ticking/ clicking from most likely the injectors and or lifters, like you could barely notice it. It was there but you had to listen for it, but it wasn't sticking out in anyway.
Skip to 6 days ago My Ktuner V.2 shows up Friday and I have about 1000 miles on car. Of course I could barely contain myself and I had to install it and flash it as soon as I got home from work. I went with the normal/23 base flash and didn't mess with an other settings. That night I drove around did some data logging and didn't notice anything out of the usual ( <14 AFRs , .49-.53 knock learn and knock count went up something like 20 that night over a few mile drive) except the car moved like a bat out of hell when you got on it... .... For the next three days the car seemed fine. I drove to and from work mostly in normal mode and would pop it in and out of sport on the way home.(man that boost feels good) I even sent some data logs to a well known tuner that gave me the thumbs up and said the car was running safe and the tune was good.
However, when I went out to start my car 2 days ago and warm it up, this is when I noticed that there was some rather louder than normal ticking almost buzzing noise going on. I didn't think much of it because it sounded like a loose washer or heat shield, and with a tiny blip of the throttle the sound seemed to vanish. So with a stressful day at work I sort of forgot about it, until the next day when I heard it again and investigated a bit further. Holding the throttle doesn't make it go away, but on the down rev it seems to vanish. This leads me to the very first time popping the hood and being confronted with the nosiest newest engine iv'e ever heard in my life. I'm not gonna lie, this made my heart flutter. I immediately flashed the ECU back to stock to see if the top end would shut the heck up and stop what nearly sounds like chattering. After the flash back to stock, I started the car and proceeded to go and have a good listen under the hood. Bringing my head close to the valve cover, I can hear the noisy injectors (don't sound too loud) but moving my head closer to the drivers side of the valve cover there is another noisy ticking /clicking maybe even tapping/ clacking noise. Please tell me I haven't bent a valve. I've run nothing but shell V Power 93 octane and even add a bit of octane booster from tank to tank which I've only filled like 4 times now.
I've called my sales man and hes trying to get me a service appointment/loaner car asap. I'm thinking I shouldn't drive it until its checked out.
If anyone is reading I'll let you know the results as soon as I find out. fingers crossed
Could be as simple as injector noise that you're not used to (DI systems are loud). Could be valve adjustment, which is inexpensive.
Could be you blew the whole thing up, hung the rods out the bottom.
The internet really can't help you much from what you're describing, take it in and get it diagnosed.

Goddamn sewing machine there.
110% sounds normal.
Thankx for replying . Is it normal for these things to get louder as they break in? I know the 2017 type-r I test drove was loud as well. It had about 8 k on it.The primary noise is the injectors and the other noise you were referring to is the cam driven mechanical fuel pump
Thanks for this. I had my Si for about 3 months, and now that the weather is getting colder, I seem to hear the ticking noise more than before, especially when accelerating in 1st and 2nd gear. I thought it was not normal, but I guess I have to learn to live with it.It sounds like it might be the typical direct injection tick that all the DI engines seem to have today. They are like mini-diesels with the way they sound. Just a thought.
Those who previously posted are correct. It's the Direct injection. It makes a tapping sound, especially when the engine is cold. This is typical of Direct injectionguys
Not sure if this is normal but when i turn on my si there is a pretty well defined fast ticking sounds coming from the top of the engine. My 9th gen did the same thing (like plugs firing) but not that loud. It only does it at ideal once i give it gas in gear or in neutral it goes away up until the needle comes down to idel then it ticks again. Hopefully this is normal just want to see if its happening to anyone else. If i have my windows up and ac blasting i csn barely hear it just for example. Maybe im just paranoid but thanks for any help you guys can give
I’ve got the same sound . Does it persist ?My '17 SI has always had the ticking, sewing machine-like sound at idle. Recently however, it has sometimes started chirping at idle and very low RPM's. It sounds like a very fast chirping cricket, and seems to occur more once the engine has warmed up. It is also not a constant sound, and seems to cut out every few seconds before returning. Honda technicians claim that they can't hear anything wrong, so maybe it's just normal?
The chirping seems to be a persistent characteristic of the engine once it warms up. I found a solution though: I traded the car in.I’ve got the same sound . Does it persist ?
I had just accepted that the Ticking was normal, as I have heard it on all the SI's I have listened to. It is louder with the hood up, but is barely audible within the car .. maybe I have the Radio turned up too far, ?On some Honda engines, the new Earth Dreams engines, they were putting little shrouds around the injectors to keep noise down. It does not appear that Honda is using them on the Si.
