Engine Ticking (another one..)

Because I'm out of warranty, my only other instinct is to come here and talk to you guys. There's so many smart people on here that it would be silly of me not to try. I can only do so much, but I'd hope that with so many people having similar issues, we'd have a few tried and true explanations, but it seems we don't.

I just ordered a stethoscope so I'll get the car up this weekend and see if I can pinpoint exactly where the noise is coming from. Maybe that will help get some insight into the issue.

I'm hesitant to just 'accept' the noise and continue like nothing is going on. That's not really my style, I can't stand when things aren't right, so I'll keep investigating. I'll update the thread if I come across anything interesting.

Yeah, I wouldn't go so far as to say anyone should simply accept this noise without identifying the root cause. It's too loud, and while it is arrhythmic, it does increase frequency with engine RPM, so it seems connected to the engine's reciprocating mass somehow. It could be as dumb as a piece of metal creaking as the engine vibrates. Metal makes funny noises under stress.

I think you're headed the right direction with the stethoscope. Some tips for using it:

The experience of listening to sound through the mechanics stethoscope is a unique experience. Be prepared to hear things you've never heard before.

Sound travels better through more dense material, so if you press the stethoscope against a part of your car/engine, and the noise seems really loud, keep probing to see if it gets louder or softer.

When trying to isolate the sound, look for sound barriers and test on both sides. For example, a bushing will dampen the sound significantly. As will a flex joint, gasket, or any other object that can move/flex. Solid blocks of metal transmit most efficiently, so place the stethoscope on either side of a sound barrier to see which side has the stronger sound level. The more flexible the object, the greater the barrier. A bushing will isolate sound a lot more than a gasket.

Cool, thanks for the tips!

Some guy crossing the street actually made a comment about my ticking during a stop light. He said it doesn't sound right and that I should go get it checked.

That's embarrassing. Almost as much as when my car used to stall every time I filled up with gas.

Embarrassing until I dusted him in the sweet smell of my cat less exhaust

I always just tell people it's the fat cam when the car stalls or surges at idle lol

Nothing to see here, move along!

Because he drove with a Kia....

Hey mate did you ever work this out? How's the car now?
I m having same noise
Thanks

[nickauger]

Sound like fire is jumping. Maybe cause by very old spark plug or bad ignition coil. You can check in the black and see if its spark.

i have the same intermittent ticking on mine.started straight after an oil change,which seems to be mentioned a lot on other threads. for some the noise has decreased or gone with mileage b ut someone had this for 20k with no other issues.
mines only when hot-silent when cold and im on 14k miles.
i certainly dont suspect theres a link to bearings ,but it would be nice to find a solution.

Interesting thanks for the info, seems a lot of people are having g the same issue. I ll link my other post where I have posted a few videos

Post rod bearings been done, weird sound https://www.m3post.com/forums/showthread.php?t=1526470

its bizarre how a lot of cases are starting after an oil change.one chap has tried different brands of oil ,but no difference.the heat shields are quite flimsy around the manifolds but its strange that each case is in the same area of the car.
mine only started about a month ago when oil changed,never heard anything before that and its most prominent under passenger side wheel. (uk rhd car).

Agreed, it s like something is being moved or not tightened correctly but I m just speculating, hopefully it is only something like that and noting relating to the engine internals

Sounds like heat shields, mine has the same noise, 2012, 45,000 miles.

[yidgyi]

Bring it to RRT in Sterling for another opinion if it still drives you crazy. Probably heat shield related though.

[Scrippy]

ITS NOT HEATSHIELDS!!!! I've had this noise since 23,000 miles, still after 2 rod bearing changes and I'm now at 162,000. It is more prevalent with new oil and let's up after the oil gets about 1,500 on it. I would love for someone to figure this out because this fucking noise is my ONLY gripe about this car and as you can read aggravates me!!!!!
