Zenedge Posted February 17, 2018 Report Share Posted February 17, 2018 Hi folks, I’ve noticed for a long time, that my car has a strange whine when on over run. I can’t usually hear it coming on the way up the gears due to the carnewal but on the way back down I can hear a faint whine from what I think is the near side of the engine compartment. It’s too faint to be positive about the location of the noise but that’s what it sounds like. It’s a whine that disappears at 2k revs, bang on 2k, every single time. I’ve had a search on here and found lots of posts on whining noises but not describing anything like this and I don’t want to get sucked into paranoia, especially as it doesn’t sound like a majorly worrying noise and it hasn’t changed since I noticed it not long after I bought the car, around a year ago. The car is a 2.7 987.1. Can anybody shed any light on this??? Thanks, G Link to comment Share on other sites More sharing options...
Dave_4 Posted February 17, 2018 Report Share Posted February 17, 2018 Mine dose this, having never owned a car with the engine sat behind my head before this, I’ve put it down to some type of belt related stuff that I know nothing about. It wasn’t mentioned after the health inspection I had post purchase, so I don’t worry about it. Probably not the answer you’re looking for, but it’s all I have.

Billzeebub Posted February 17, 2018 Report Share Posted February 17, 2018 I have owned four 986 3.2s, doing a combined mileage of around 100k. Never had any kind of mechanical issue/failure. Whines from the engine on every one. Lots of lovely engine related noises from just behind you which you will never experience on the usual dull front engined cars. It's probably nothing to worry about, but get booked into your local specialist for a reassurance inspection if in doubt. Link to comment Share on other sites More sharing options...
bagss2 Posted February 17, 2018 Report Share Posted February 17, 2018 Possibly your water-pump is on its way out. The first sign is a whine.... Cheers, Baggers. Link to comment Share on other sites More sharing options...
V987S Posted February 17, 2018 Report Share Posted February 17, 2018 My car has the same symptoms you have described for at least several years now. Initially thought it was water pump-related, but having had the OPC visually inspect the pump, it looked fine. I think it is normal. Link to comment Share on other sites More sharing options...
Zenedge Posted February 17, 2018 Author Report Share Posted February 17, 2018 After reading plenty of threads about whining, I suspected water pump at first but I think it’s just too consistent to be a bearing failure... it starts and stops at exactly 2k every time without fail, sounds like it’s something that’s supposed to come on/off at a set rpm. Im not gonna worry too much about it for now based on these replies. Thanks folks, Gordon. Link to comment Share on other sites More sharing options...
perleman Posted February 18, 2018 Report Share Posted February 18, 2018 I had this on my 997, was alternator whine from the amp I had installed! Took me ages to figure it out - only realised one day when the head unit stopped responding as I drove along so I took off the detachable key pad thingy to force reset it & suddenly the whining stopped, restarted again when I put it back & I realised Also though the engines are very whiney Other culprits are water pump or wheel bearing Link to comment Share on other sites More sharing options...
That986 Posted February 19, 2018 Report Share Posted February 19, 2018 It could just be a characteristic of the exhaust tbh, they can make strange noises at times. Link to comment Share on other sites More sharing options...
