Whining-noise

[Kenbo1000]

Hi Guys I need a bit of help here.

Started the Boxster yesterday and it made a horrible noise similar to a starter motor stuck in mesh. I drove about 10 feet then parked it up as I was on my way out. When I came back I started the car again the noise had seemed to have gone. Took it for a drive and it seemed ok but on further listening it still there but very faint. Today I removed the engine panels to see if I could trace the noise but no joy. There are no management lights on and the engine seems to be running as normal other than for the noise. It’s now like a very low whine.

Anyone got any ideas on where to check. I did listen to a YouTube clip of a starter motor not releasing and it was the same horrible noise but stayed on mine until it was parked up, about 2-3 minutes.

any help would be appreciated.

Thanks Ken.

Remove the drive belt and spin all the pulleys, see if that determines it, in the first instance.

Thanks Bally.

that’s my first job in the morning. Just have to get on with it until I find the problem.

As Bally says and also remember you can run the engine BREIFLY without the belt and if the sound dissapears you know it is somewhere on the belt run...

Cheers bud.

did wonder about that. Will spin them first to see if there is anything obvious. Still have a niggle it’s the starter motor but will check everything else first. If it is the starter I might as well change the AOS and the oil Cooler seals. But we will see.

If it sounds like starter motor it could well be just that.  It’s fairly common for the Bendix to stick. Some have been able to remove and clean and get some more life out of them but typically eventually you end up with a new one.

Update. Removed belt and no untoward noises from any pulleys in fact it was just as normal so put it back together and went for a little drive and it starts to whine when it gets under a little load. Put into neutral and rolled a little and the noise was still there. Standing still and ticking over no bother. Plugged my reader in and no faults found. Anybody got any ideas….

Found out that we now have a Porsche specialist not 5 miles away. AHRS Porsche. He is located near Bishop Auckland and specialises in engine rebuilds. He used to be a Porsche racing mechanic in Kent. Anyhow took it to him and he immediately diagnosed that it was the power steering pump. It needed topping up with fluid. He did say it’s quite common and scares the daylights out of owners. One for the memory bank I think.
Anyway he is going to look at it later to see if the rack is leaking.

Many thanks to everyone who commented with suggestions.

Good to have at least diagnosed the general issue and thanks for sharing. Obviously one to keep an eye on and good luck on any further remedial work to sort.
