Can anyone help diagnose this ticking noise for me? Engine sounds fine on idle and it only starts ticking at a specific RPM ~1.75. It will tick consistently at around there. Otherwise, it goes away. It has been cold recently and I let it sit for 3 days, pretty new to cold weather. Is it really possible to tick like this if I don't let it heat up? I drove it for 3 minutes, heard it, then turned back home and have been reving and testing it out for a few minutes. The noise seems to be coming from the top of the engine, seemingly under the RSTurbo cover. I got the spark plugs and oil replaced (5W-30) last week. Anyone got a clue?

I also must add that the engine mounts need replacing, but I'm waiting to take out my transmission mount so I can have both of them polyfilled before i install the new mounts. Although I'm not sure if the mounts are responsible for this kind of ticking. Just putting it out there just in case. Thanks.

Did the noise start AFTER the spark plugs or has it been happening before?

It happened after at least from what I could tell. I had someone do it for me, haven’t open it up and checked since but here’s more: Streamable Video

I would take a sparkplug out and make sure that they are Denso or NGK plugs.

ill check it out, thanks. from what u heard is it possible to be timing components in the engine??

Also could these fluids be a reason for the ticking?

these are the spark plugs the mechanic put in

Spark plugs look correct from that part number I pull up on my side.

Was a fuel system clean done? It really sounds like injector tick but these cars are not known for that. Any Malfunction Lights on? Timing chain is a possibility HOWEVER, unlikely as the noise you recorded is not similar enough.

nada. i had it inspected 2 weeks ago and they said nothing. i mean there was none of that ticking until earlier this week which is annoying

I would try a fuel system clean. Like a full induction service and if it does not go away, have a Hyundai technician take a look at it. I don't know how well parts from amazon are but I'd be worried the spark plugs are not correct.

i planned on using some CRC valve turbo cleaner and fuel injector cleaners. but wait till my next oil change since i just had it changed. Would that not be enough? Or would i need a full on actual fuel cleaning service?

also do u recommend a hyundai technician over a local mechanic to check my engine components, etc.?

 

[ggthomps23]

I always recommend a technician over a mechanic. Mechanics throw parts at things. Technicians Diagnose.
It's up to you how you want to do it. But I would start with a fuel induction system cleaning from a dealer and go from there. If this were at my shop that is what we would start with after diagnosing and finding spark is good and coils are good. I know I probably don't need to say this but make sure there is the correct amount of oil in the car before anything else. Good luck.

Ugh I wanna stay away from stealerships. I’m gonna open up the engine myself with a friend. We’ll see what’s up with it. I don’t think it’s rod knock either bc the symptoms are completely different. Fingers crossed. It’s freakin bugging me not knowing what it is though.

You should try to find where the noise is coming from.

Take a looong screwdriver, and place the driver side of it against various area of the engine. Put your ear against the handle. try to find which area gets the loudest, doing this.

BUT, to me it sounds like its coming from outside the engine.
When cold, see if any of the heat shields or cover panel fasteners are loose.

Will do but after having someone rev it for me and listening to it it sounds like it’s coming from inside the engine in the front? Idk how accurate it is to diagnose sound without a screwdriver it just sound like it’s most likely coming from the front of the engine

[kristuhphur]

so I pretty much confirmed where it is. I didn’t even need to use that method bc it’s so obvious. But here is a perfect video showcasing where and a perfect rev spot where the ticking was insanely loud Streamable Video

Hey. I opened up the cover and the spark plugs are champion. Are these the wrong ones?

5 miles before the chain jumped

You "guy" is trying to put a fast one on you, if you paid for ngk/denso plug price.
When engineeres design the combustion chamber they practically design it around which spark plugs are going to be used.

The chain jumping timing, may be unrelated, but your "guy" might have had too much fun "testing" his work.

On the bright side. If power and engine operation seems fine, then you might have gotten lucky, and just need to replace the chain (not needing a head rebuild). Replacing the chain is not hard, it's getting to the chain to do the work, that's a PITA.
