Unknown noise ... someone help please

[chakota]

Hi All,
First of all happy new year to all bongo owners.
I will try to describe my problem, To let you understand i am a bit deaf so noises may go un-noticed by me. I took my wife to tesco yesterday shopping , first time she has been in it for months. As we were going round bends she said there was a graunching type of noise , she thinks it was near-side rear. Also i did hear a noise when i was accelerating up a small hill hard to describe what it sounds like (perhaps rattlely).When its on the flat it is fine no noise at all. Coincidentally i put some product called cataclean in day beforehand , after 30 mile drive i stopped to re-fill with petrol i could smell like burning rubber with a high temprature type of smell (sorry cannot think of another way to describe it.) . Bongo runs excellent its just the noises appeared yesterday (day after i added additive) Dont know if its just co-incidental. All oils and coolant at normal.
Anyway has anyone got an inkling to my problem .
Bong is 2 wheel drive , 2.5 V6 1999 model.

Many thanks all ........... Harry

I may be way off ( and probably am )but its worth a look, When we were in europe earlier this year we had a similar noise to the one your describing and it turned out to be low coolant causing the water to swoosh in the water system behind the dash, the noise was only there under acceleration and up hills, on the flat it went away, me and dan couldn't decide whether the noise was front or rear, it wasn't until it started to overheat the next day and we topped it up that the noise went away, for me it was the begining of head gasket issue that were sorted by the dealer when i returned to england .

many thanks for your reply , i shall have a look at cooling system more closely asap.

Many thanks.........Harry

It seems a little coincidental that you used "cataclean" recently and now you have a rattling type noise and accompanying burning smell coming from (possibly) The exhaust area...

From what i can gather cataclean "steam cleans" the catalytic converter, supposedly improving the performance/emissions. Could i ask what prompted you to try the product? had you sensed performance falling off at all, or was it a case of chucking it in as a precation?

I have no evidence to suggest that the product may have "overcleaned" (for want of a better term) the exhaust system, but could the addition of the product killed a failing cat? (do the petrol bongo's have a cat? I'm not clued up on them).

I'd be tempted to whip the bongo on a ramp and give the whole exhaust system a damn good shake to listen out for tell tale signs of a collapsed silencer baffle, or (if fitted) a rattling cat (if the cat does rattle it's fluffed i'm afraid)

Have you cut a cat up Steve? Like extruded honeycombe...

[bigdaddycain]

Aye... like a metal malteser

I saw a post on this forum about the product .. seemed favourable so read some reviews which were favourable also , but not the link you have posted (wish i had) The reason i tried it is because my bongo has done 102,000 miles and i thought perhaps a clean of the injectors and cat would be in order. She runs perfect no smoke or other issues , i suppose its what you would call a bit of tlc (maybe too much). Not being able to get under cars anymore i think its a job for my local mechanic he done my cambelt , service, etc .
Just hope i have not done any damage to our baby

Many thanks for your reply to my query ... Harry

[MAZABON]

hope you get it sorted but this situation brings that old saying to mind

if it aint broke dont try to fix it

[bigdaddycain]

Oh i understand your thought and drive to try the product Chakota, After research you thought what harm could it do? I'm not saying it definitely has caused any damage, it could just be coincidental. And your preventative maintenance attitiude is very prudent indeed Without further investigation it's difficult to suggest a solution really, exept it may well be worth a visit to a trusted exhaust fitter that could have a fiddle around with the exhaust to either condemn it, or give it the all clear so that you could search elsewhere for the source of the annoying rattle...

Many thanks for your opinion bdc , do you know a link for exhaust detail for the 2.5 lt V6 1999 , looks a bit weird underneath... does the V6 have a cat. ?

Many thanks for your input.....Harry

Does this help..........http://www.lushprojects.com/bongopartsm ... mgno=.html

[bigdaddycain]

It does indeed help very much, thank you Teenmal! I always forget about the lushprojects parts database So the answer is yes, there is indeed a Catalytic converter in the system...

Nearside front brake ??

[bigdaddycain]

Possibly... The addition of cataclean, then the noise could well be nothing more than a coincidence.

Nearside front brake ??

This could be the problem as when going round corners my wife says it makes a noise pads look ok so does disc , think i will have to explore further .

Many thanks Hadyn
