MG ZS 120+ noisy - Newby
I bought an MG ZS120+ in November 2002 and thought, at the time, that the engine was a bit noisy. On Monday (23/6/2003), this week, we dcided that the noise was so bad that we should do something about it. The car has 3500 miles on the clock. The Rover/MG dealer diagnosed the noise as being from the rear exhaust box and, next day, fitted a new one with the explanation that the spot welds must have gone in the box and was sending the box back to the manufacturer. I find that the engine is still noisy. It sounds like "bag of bones" rattling and I'm a bit concerned that it caused by something which, in about 4 months time could be an expensive "out of warrenty" job. Any ideas, suggestions, please?

Could you clarify the engine noise? What 'sort' of noise and at what speed/load?

The K series engine is known for being a little vocal - due to its lightweight construction

David Lacey,
Thank you for a prompt reply.
The noise sounds like everything is loose. Probably the sound you would get if all the tolerances of all the engine parts were at their maximum. The noise is particularly bad when reversing or starting off. In othere words, it's not related to speed. The changing of the exhaust box made a slight - very slight - difference. It's the kind of noise you would get from a clapped out 150,000 mile engine. That's the best I can do to explain it.
Thanks again,
Newby Stanley.

Sounds like piston slap to me......does it go away when hot?

Try a search on \'Piston Slap\' here - I think it has been discussed before..
MG ZS 120 noisy - Newby
David Lacey,
The problem is that it cannot be heard when the car is moving. In other words, there is a general overall noise when the car is moving, but that's to be expected because soundproofing in this car seems to be non-existant. To soundproof the car using a sheet of adhesive backed material from Steve Biithell would cost about £70.00 - but that doesn't get rid of the noise when starting up. I will check next time we use the car to see (hear) if it is quieter when hot. Thanks for your interest. I have looked at the "piston slap" threads but, somehow, I feel that's not it. I'm still baffled. I'll sort it! But keep the advise coming. I'm always willing to learn.
Thanks again,
Newby Stanley.

Have you compared your car to another similar car, perhaps at the dealership where you bought yours?

That seems a sensible solution - perhaps trade it in for the Diesel version - the offers are fairly strong at the moment!
MG ZS 120 noisy - Newby
It did occur to me to compare it to a similar car but I just haven't had a chance to do it yet. I intend to, however. As far as trading it in for a diesel!! I've just bought the car - it would be money down the drain to do that. However, thanks for the suggestion. It will probably be about another week or so before I can compare it - I've a lot on at the monent.
Ta, and thankk you.

There is a problem with some MGs in that they are fitted with the wrong engine stabilizer bar . This gives extremely rough running at idle. The stabilizer bar wrongly fitted to the 4cyl is that intended for the v6. There should be a colour code on the stabilzer. see which youve got, let me know . I cant remember the correct colour but will find out.MG are reluctant to admit this

Hi, Grumbler,
I have had further words with the MG dealer from whom I bought the car and re-emphasized my concern. I pointed out that I didn't want the dealer to tell me in six months time when the engine blew up that "it was out of warrenty". On 21st of July they are bringing me a loan car (no charge) and will keep my car for two days (or so) to check it out thoroughly. I will comment to the dealer your remarks about the stabilizer bar. I'll have a look at mine - let you know. As a matter of interest, was the incorrect bar fitted as a factory error, or design change! Come to think of it you answered my question in your comment - FACTORY ERROR!
Thanks a lot!

The other car may well have the same problem!I will get back to you with the colour codes. They wont admit anything

Hello Mr Newby,
Heres the info. Your lower engine tie bar should have a green paint mark on the bar itself or the bushes. If its yellow youve got the wrong one. The correct part No is KKH 102450. If you get no help from your dealer try Mr Martin James, Service Director, Sales Block, MG Rover Group, PO Box 41, Birmingham B31 2TV.

I should like to hear how you get on.

Hi, Grumbler,
I still haven't looked at my engine tie bar, however ----
on 22nd. July the dealer brought me a loan car (prearranged) and took my car away. Yesterday morning (23rd.) I receiveds a call from the dealer. The gist of the call was that the engine was short of oil!!! 4500 miles on the clock! The upshot of it is that they topped up the oil and the engine is lovely now, however--- when my car was brought back I was handed a Rover Tchnical Bulletin dated 18.05.94 No. 0003 issue 1 in which it quoted oil consumption problem on all models registered from January 1993 and it states thatacceptable maximum oil usage when confirmed by yourselves (dealers staff) etc. VEHICLE MILEAGE 3000 MILES (5000 Kilometres) ONWARDS
1000 miles per pint or 850 miles per 1/2 litre.
Since Dec 1994 I have had (new) a Mini Cooper, MGF, Rover 200 (1.8 engine) and have not heard of this problem before. The service guy said I should have been told of the propensity for oil burning at this rate when I boight the car!
Have you heard anything like this. The car, by the way is (touch wood) running like a sewing machine now.
Comments???

So, are you saying that since you got the car in November 2002 you've not checked the oil??? The handbook says that you should do weekly checks like tyres & pressures, screenwash and oil. If the engine had failed due to lack of oil, the dealer would well be in his rights to say 'no claim'. My own car uses no oil but it still gets checked weekly like all the other parts I'm responsible. If the oil level drops suddenly at least I'm aware at the early stages of something more serious. Engines these days are designed to use a bit of oil to help with upper cylinder lubrication and contribute to the longevity of engine life.

If as is indicated in this thread, the oil was not checked in 8 months or 4,500 miles, I too am astounded! First thing I do with a new car is to check the oil weekly to get an idea of how much oil it uses!
MG ZS 120+ noisy - Newby
Hello, Robin the technician,
I also am an engineer and have stripped, rebuilt and tuned engines (around 45 years ago). I am very much aware of the checks that should be carried out on cars but, over the past few years have discovered that all the cars I have purchased new have not needed checks other than windscreen washers, tyres pressures. When you buy a new car and have NO INDICATION OF OIL LOSS, OVERHEATING, OIL LEAKAGE or any other sort of deficiencies with a car run properly ( not flogged or overloaded or misused) and always fully, correctly serviced it comes as a shock to find that the amount of oil that is acceptable to be lost in a new car is KNOWN to the service personnel but not passed on to the customer. The dealer admitted that I should have been informed. The car is running very nicely (touch wood) and I shall certainly check my oil more frequently now. Incidentally we are down to one car now - bacause between us we were only doing a combined total of 8,000 miles per annum. Incidentally, you surprise me with your comment - if your oil level drops suddenly you would be aware of something more serious - I would have thought you would know why it dropped suddenly, black smoke, oil on the drive oron the garage floor!. Thank you for your comments.

Hi, Grumbler,
I've checked the rear stabiliser bar but, to be honest I can't make out any colour. Tha whole thing looks black without any indication of colour. If the marking is small I probably wouldn't be able to see it. Where would the mark be and what size. I mean is it a stripe, total colour code, spot. I don't really know what I'm looking for.
Thanks, anyway,
Newby.

I find it hard to believe that the problem was cured by adding oil. If the oil level droppedto the point where the oil pressure was not maintained it is true that the engine would become noisy
but you would have only 10 secs of engine life left before it self destructed.Furthermore there would be an oil pressure warning light to indicate what was happening.
Even if you were useing 1 pt per 1000 miles after 4000 miles you would still have at least half a gallon left in the engine.

I dont think that your dealer has told you the full story.
MG ZS 120+ noisy - Newby
Hi, Grumbler,
The engine takes about 7.5 pints of oil. I agree that there is something fishy but, at the end of the day, what I want is a car that is trouble free and reliable, apart from all the other reasons for buying a car. The car is running fine (touch wood) - no I'm not superstitious but I dislike tempting providence. The problem, whatever it was, seems to have been cured. What more can I ask for? The result is what I want.
It would be, I think, a waste of time and energy to pursue the matter further, unless of course, I hear from anyone else who has had a similar problem - and knows the cure. C'est la vie!
Thanks again.
Newby.

Newby, are you confirming that you never checked the oil during 8 months? even when it first started to sound noisy?
MG ZS 120+ noisy - Robin the Technician
Hi Nweby,
You seem to contradict yourself in that you 'say' you are fully aware of the checks needed on cars but- and I assume this is so- you ignored a most vital part and neglected to check the oil. Irrespective of mileage/ carefull driving/ flogging, it is still necessary to check the oil weekly. Cars can use oil and you can be blissfully unaware of it- unless you drive looking in the rear view mirror all the time. I had an Allegro (for my sins) a few years ago and it did 300 miles to the pint of oil. If you took the plugs out they were clean as they should be- the exhaust was clean and exhibited no smoke either stationary or on acceleration/ decelleration. When I finally got the motor out and stripped it down, the bores were extremely glazed. All i did was to use a glazebuster and reassemble - not even replacing the rings and it never used a drop of oil after that.
When i said by checking the oil weekly this could alert you to a potential problem that's precisely it. At least you can go straight to the dealer if you get a sudden loos of oil- rather than not bother and end up with a knackered unit and nobodys fault but yours.
