Forum:
Can anyone identify the source of this noise. It comes in at about 3000rpm in all gears and sounds like a heat shield or plate resonating, it stops about 800rpm later. I have just driven a mates car and it makes almost the same noise. He has replaced the exhaust and cat on his to try and eliminate it to no avail.
Any ideas?
i cant believe no one can
i cant believe no one can assist with this one
Hi, I have the same problem
Hi,
I have the same problem with my Sportrak. I have had it for a few years now.I had the exhaust changed thinking it was that - but it was not. Must be the catalyst then.......
Cat
Probably the shield which coats the catalyst.
Note ... if its J reg or earlier the cat can legally be removed. Replace with a longer front exhaust pipe. Later than J reg must have a cat or it fails on MOT even if CO2 is below the limit.
Rattle on Exhaust.
I have two Sportraks and they both rattle and it is the Catalytic Convertor. One has had the shield removed to no avail and continues to pass it's MOT regardless. One has been like it for so long, at least 9 years and is fine once in 5th gear and over 2600rpm. On accelration in all gears it is noisy but I have got used to it. I must admit when I brought the 2nd Sportrak last year I was looking forward to not having the same but, the noise was there.
I have a spare 2nd hand Cat but have never replaced either. The intention was to replace the first but when the second did the same I felt it may prove a waste of time till it fails on emmissions.
