Hey OP..any updates on this...TODAY I NOTICED MY BRZ MAKING THE SAME NOISE FOR THE FIRST TIME.


22K miles. Baby the car. Car was warm and I was waiting at the bank drive through. Pulled up after the car was off for 3 min and heard it clearly..same as your first video. Then noticed it at idle when I got home for 30 seconds.


What happened in your case???

That's normal if it's the tensioner pulley.

imo your first video sounds weird but I wouldn't freak out, especially if it's intermittent, in the second video the noise doesn't last long enough but again doesn't worry me.

Folks on the forum say "that noise is not right", Dealership techs say "Its normal". I would agree with the forum members since the sound is no where near what I would say sounds like a modern new low mileage engine of any level. However I also know that sometimes owners hear things that the average knowledgeable tech rightfully doesnt bat an eyelash at. I have an especially critical ear and think that might play into it. But on another opposing point I also took the car in for both the fuel pump crickets and the window seal/squeak issue. Both which now sound like are back just weeks after being in the shop. I also know that the brand new cars dont sound like this on the lot.

IM COMFOOSED!!!!

Im almost at the point where Im going to take the advice of a wise old machinist I used to work with and get a louder stereo each time I hear a new noise until I don't hear noises anymore. I mean once I put on the exhaust I plan to put on I kind of doubt Ill be able to hear the engine compartment noise anyway and the car still performs well.

I realize this is a brand new engine but do the WRX and other boxer subbies have a similar loud topend sound as well? I heard someone say that ths subbie boxers were just loud mechanically. Could we all just be a bit too critical?

Sometimes this knock is found to be fuel pump. I noticed this when i started putting Arco gas. Premium of course.

I swapped to Shell and Chevron and its gone. Imo dont worry unless you find problems when accelerating. My 90 pickup does this too on super cheap gas.

This one isnt normal. Theres 2 knocks going on.

^^^cause for concern.


This is normal.

Also, @BRZnut

Op said dealer said it was normal because of fuel pump. Op believes it may be bad gas.

So, I suspect rocker arms are going, on a babied BRZ with 22K miles! DD, no track, never been above 5K RPM. Ridiculous. Since very intermittent and only after I stop and then restart a fully warmed engine, I am just going to watch and see if it gets worse. If it does, no time or patience to deal with an engine repair. Will just trade it in for a non-Subaru.
