It sounds quite similar to the noise my first F made just before the cam belt tensioner exploded it's bearings all over the place. I would personally avoid driving the car until I was sure. Hopefully it's something with less chance of causing the engine to beat it's self to death from the inside.

Aha! I've experienced this exact noise before (the kettle noise), both with my ex Rover 45 and the TF, and only really when cold. It's the oil filter. No really! Trust me on this.

I was baffled for months about the noise on the Rover, and I had a listen with the screwdriver against my ear underneath the car, landed it on the oil filter and it was that! Obviously was completely full or faulty, and there was some sort of pressure relief whining. Changed the filter and it was fine ever since.

I then got the TF (I'm a new TF owner by the way and loving it), which hadn't been serviced for ages as it turned out, which was making the exact same noise. Changed the three year old oil filter and all was fine.

Sounds mad, but before you do anything, just do an oil and filter change and that loud whining kettle noise you hear in the video should dissapear.

Thats a very interesting reply, thanks martin... ive not heard such a noise as that ever - yet, and it would not occur to me it might be a fluid whine, so to hear from someone who has experienced such a noise and cured the problem is good to discover...

Thanks for the replies guys I've determined that the pitch and speed of the whine is connected to the speed of the engine so that would point at something under the cam belt cover? I hadn't thought about the oil filter, it is due a change, but would it cause a whine that changes with the speed of the engine? I have no idea so please let me know on that one.

I'll investigate the filter but I'm pretty convinced its the cam belt tensioner so going to do that myself as I think I can do that (leaving the existing 2 month old belt on) without locking the flywheel or removing the uber tight crankshaft bolt.

And onto my next problem.... Now that the tf isn't drivable I was planning to use the missus's civic to get to work, dropping her off on the way. So we get out there and now that won't fire up either, it's just turning over and over! So now where both on the bus and I have no way of picking up the parts I need. Marvellous!

sxxxt i would go back to bed for an hour and start the day again.fuel???? getting a spark?????
I just need to convince my boss about that :lol: Fuel is all good only recently been filled up, could be dodgy fuel i suppose, hmm. I'm unsure about the spark as I just had to bail and run for the bus. We have RAC cover for both cars so might just let them sort out the civic tonight. Ive never been in a situation where both cars are laid up before, the civic has always been faultless... gremlins must be playing havoc with me this week.

The pitch of the whine gets higher when the engine is revved, as the oil pump is being driven faster, thus resulting in higher oil pressure and a speed related whine. I only wish I'd video'd both of my cars when they were doing it as the sound and charactaristics of your whine are identical.

Trust me, just do an oil and filter change first. It's easier to do that first (especially if needs doing ayway) than go through the process of doing the cambelt tensioner. Or at least have a listen to the oil filter through a long screwdriver when it's making the noise.

Hope this does the trick!

Hi mate I took your advice and listened to the filter through a spanner and it definitely amplified the sound so I think you are spot on with your diagnosis! Ill be getting the parts or a oil and filter change asap to see if that cures it. Hopefully it does :)

yeah I'm very pleased, it is weird though as I haven't heard the noise at all today even before the filter and oil change, anyway fingers crossed it doesn't come back. The used oil did look very old so I'm betting it hadn't been done for a long time, it was a mg rover branded filter that came off btw. Hopefully its the same problem you're having as it is a nice easy fix and good to know the thread's been useful! :)

This is fantastic news!:bgrin: Glad to hear it's done the trick so far, so much easier than removing the cambelt to find it wasn't that after all. And I'm glad you gave the filter change a go because it's such an unusual thing to make such a noise. Hope it stays quiet!

Give it a go! It's a wierd noise, and I thought it was either the alternator or cambelt when it first appeared on my old Rover 45. Was literally about to take all the external belts off before I had a poke round with the screwdriver and landed on the oil fliter. Hope this sorts the problem!

So have I discovered another unique K-series charactaristic? The fact they moan and whine when they need a service?

Im pleased I made the video and that you saw it, id of been scratching my head for days otherwise and still not even thought about the oil filter. Nice one :broon:

I think you may of, funny thing is id been meaning to do the oil change for a few weeks, id done plugs, ht leads, air filter, coolant change, and had the cam belt done by a garage. Think it was my cars way of saying "Oi, you're not finished yet c'mon finish the job" :lol:

Like a woman?
I'm astonished this thread managed to get to the bottom of page two before someone mentioned the horrible whining noise coming from the passenger seat.
Good man MiniM for bringing it up as it has been a constant pain in the neck for me for the last 20 odd years.

I fitted one of these




Never had a problem since

Thanks to everyone who contributed to this thread. Had exactly the same noise on my TF 135 and was convinced the cambelt tensioner was knackered (even though it had done less than 5,000 miles since it was changed in 2012).

Anyway, as always I had a good scout through the threads on MG-Rover before I started work and saw this. Changed the oil and filter this morning (Genuine MG Rover filter and Castol Magnatec) and hey presto no whistling kettle. So much respect and thanks to you all!!

Found this thread the other day, had not found it before as I normally look for r25/mg zr. I too have had this problem and the oil filter change made the difference.
Some months ago my 1.8 zr 120 started making a strange whining noise – but not as soon as I started the car, it took a few minutes to start making its noise and the longer it ran then it changed note a bit. But after a few more minutes say 10, it would make a bit of a click and then the noise would stop. Could easily be heard from 30-40 feet away. Seemed noisiest near the bottom of the engine near the crank pulley.

I knew it was not the alternator or PAS belt as it still made the noise when the belts were off the bottom pulley. Found a thread somewhere that suggested the pulley can make a noise if the rubber vibration ring in the pulley has failed, so got that changed, but made no difference. Had bought a new water pump and belt tensioner thinking that they would be the next things to try. But then found this thread and had a crawl under the front of the car and wow what a noise from the filter.

Talking to a mate of mine he recalled an occasion when the mechanic that lives opposite him had a car up on a ramp with a few people under it trying to find where a noise was coming from – it had just had a new exhaust fitted, but it turned out to be a noise from the oil filter. Wasn’t a Rover/MG though.
My zr had a genuine mg rover filter, have replaced it with another genuine one.

Well done whoever found the solution to this.
