So I'm getting a buzzing/rattle coming from the engine area at 3000 RPM, when i'm giving it 1/4 or so throttle. This happens at exactly 3000 rpm, and stops when the revs go above or drop below. It happens in gear, and in neutral, but only when I give it a good push of throttle. Meaning if i slowly creep it up to 3k, i don't hear it, but if I give it a good blip, or accelerate at a normal rate in gear, I hear it. Any suggestions? I have heard everything from loose
exhaust
brackets to oil pump issues.
ive actually got a similar rattle/buzz at 3000rpm only its once in a while not all the time.
It's probably a loose heat shield. Does the sound go away when the engine is hot?
One of my heat shields (rear right of the car) rattles and buzzes but stops once the
exhaust
is hot and the fittings have expanded.
It's not really worth doing anything about, it's not causing any harm and is temporary.
It's still intermittently around when warm. It seems to have more to do with how hard i stab the throttle, than how warm the car is. I've still got until August on the CPO warranty, so I was making a punch list of "free fixes" that I was going to have them do before that gravy train runs out anyway.
My car has done this from new. It's not an annoyance unless you concentrate on it. I've been told that these engines have a natural harmonic period at 3000 RPM and the vibration is perfectly normal. I've long given up obsessing over it.
I wish I could remember if it did it since I got it. I guess since I have a rattle/buzz in the driver side door that's driving me up a wall, I might just be more "tuned in" to rattles now. Hyper Vigilance is my curse.
All of the
Caymans
I have had did this. Perfectly normal.
Well, "Perfectly Normal" for a
Porsche
.
I'm starting to realize perfectly normal is a relative term. :thanks:
Brought it in this morning for this. Waiting to hear.
Well they were unable to find the source of the noise today. They thought it was a cam phasing issue, but apparently it was not.
So they did the oil pressure sending unit TSB that people on here talked about and they claim the noise is gone. I will pick it up tonight. They also replaced my hatch struts which were leaking, and my ash tray which was peeling badly.
I am having the exact same problem with my 99
boxster
with 2.5L engine. Was the problem oil pressure sending unit? I think my
boxster
doesn't have such a thing.
