Sound Video of BaBaKa's Engine Squeak

Paula · 7-20-09, 14:00

Hi Guys,

I have just done a video of BaBaKa's squeak which I first noticed last Saturday night and is intermittent.

I started her up and for the first 2-3 minutes the engine is dead quiet and then you get the usual HLA's ticking all the time when the oil starts to warm up.

You will hear the low pitched squeak at the beginning of the video and it is at it's worst from 32 seconds to 21 seconds and then it goes altogether.

What do you think?

Paula that sound more clattery, if it is it could be the hydraulic tensioner, very dangerous to drive if it is!! Get it looked at ASAP!

Hi Mark,

This was my original post:

http://www.mx6.com/forums/united-kin...w-her-age.html (Is Ba Ba Ka starting to show her age?)

I had a brand new Mazda HT fitted by Nick Clulee less than 3000 miles ago together with the Cambelt and Water Pump.

He looked at all the other belts and did not consider them worth changing as they would have to be readjusted as soon as I had done a few miles back in Surrey.

You're sure??

Hi again Mark,

Sorry the car has done 5000 miles since the HT was done.

It was a Mazda one too.

Hi again Guys,

I have sprayed some WD40 around the belts and the noise is still there.

The noise seems to be coming from a pulley but further back on the engine than the alternator.

The noise takes a couple of minutes to start again once the engine has cooled down a little.

But the noise is similar to an alternator squeak.

I think I can hear what you are talking about, but I wouldnt describe it as a squeek but thats by the by. Mine used to do this before I fixed my broken engine mount bolts. the noise was the water pump pully/belts, could it be that the water pump pullye bearings are worn perhaps? OR is it something a bit simpler such as the timing belt cover loose?

just thinking furthur, this noise, I am wandering if its something inside the engine, hows the oil and what oil do you use?

actually paula, if you look, past the oil dipstick, past the water pump pully, you will see another pully, right at the back, low down, is it that one thats making the noise? I cant remember which belt it is that goes round that, but that could be the problem....

possibly the power steering pump tensioner pully bearing OR the bearing in the power steering pump itself if the noise is coming from the back. If its the tensioner pully, you can get a replacement bearing from probestore and very easy to remove and drift in the new one.

Hi Guys,

Wow, thanks for all your suggestions.

Clive, I use Silkolene Pro S 5W/40 and it was changed only 1000 miles ago along with a Mazda Oil Filter. The engine never uses any oil and there is no blue from the exhaust at any time. The HLA rattle has been there ever since I bought the car 15,000 miles ago at 93K but since using the Silkolene, it has stopped any HLA noise on start-up until it's been in there for around 5 thousand miles. When the engine is warmed up, it gets the usual HLA rattle which you can hear on the video but my Mazda dealer said this is quite normal at this mileage and is nothing to be concerned about.

Paul and Clive, it does sound like a worn pulley bearing to me so I will get my Mazda dealer to listen to it. They have listening devices such as a hollow tube ( I think ) which should locate the noise.

I will report back when I know more.

Cheers

Paula

PS. I sprayed the WD40 on the belts that I could visibly see to see if it stopped the chaffing noise ( a better description ) as I used to do this on the alternator belt of my Volvo 340 and it ceased immediately until it dried out again. I replaced the belt in the end. So it could possibly be a belt that I could not get at with the WD40 earlier?

PPS. Clive, Nick Clulee fitted a new Water Pump along with the Hydraulic Tensioner and new Cambelt 5000 miles ago.

Hiya again Paul,

Could it be like this report?

Sorry for the panic but I didn't realise you already had the HT replaced.
Going back to the power steering pump pully bearing, have a listen to it while someone turns the steering and puts some pressure on it.

Hiya Mark,

I'll forgive you .....

I will do that in the morning, thanks.

Must be honest sounds like it could be the HT to me too. does it still clatter like this when you rev the engine? and is the clatterying then not in time with the engine revs? As these were the symptoms when my HT needed replacing. Not being funny but I have heard some other members slagging off this nick cooly guy. Just what I heard. Long way to go too.

Paula · 7-21-09, 12:34

Hi Dave,

When I rev the engine the noise goes away.

The noise only happens when the engine is warmed up.

Also it's only on tickover and is intermittent.

As soon as I slightly raise the revs the noise goes altogether.

I have just been outside to check again and will post up more videos.

Nick Clulee used a genuine Mazda HT that I brought back from the USA at half the price that I would have been robbed for over here.

I cannot see one being being faulty after 5000 miles.

Nick Clulee is an awesome mechanic and very honest. He is very much old school.

He ran a Mazda wokshop in Sheffield and knows 626's, MX6's, RX 7's etc like the back of his hand.

The Sheffield Mazda dealer went bust because Mazda cars were far too reliable in the 90's and they never came back for serious repair apart from general servicing. Not so these days, I'm afraid with RX 8's giving all sorts of trouble and Ford's cheapening down of the Mazda range.

This made Nick start his own business and he has never looked back.

Nick is also very reasonable and I can tell you that a trip to Sheffield and back is well worth the fuel when the cost savings of his work are taken into account.

Einstein (John) our moderator recommend him to me by the way and we all know that John's knowledge of our cars is legendary.

Take care and thanks hun for your input.

It's so great on here.

Hi again Guys,

Just come back from outside in the rain.

Here is a video of my dead silent engine on Start-up (Thank you Silkolene Pro S 5W/40)

After 10 minutes or so the chuffing noise begins with the normal HLA rattle but when I rev the engine slightly, the chuffing noise goes:
