HI All,

Got a blow from where the front pipe meets the cat.

No big deal, but its the 2nd time I've had it sealed in 3 months....

Got the car in Jan, blow started about 2 weeks later - took to exhaust place who said pipe was brand new but had been fitted without any exhaust paste, result, all sorted.

Month later MOT, blow from same place, resealed - hmmm strange.

Month later its back - Is this a known issue or am I just dealing with muppets who cant seal an exhaust ?

Photos would help. If the two pipes are different diameters - and tolerances can vary - then the putty is trying to fill too big a gap and it can fail more easily. Plus the 3 pot engine does rock more so the exhaust takes a hammering, hence the failure of the exhaust manifold on them.

Cheers Taurus,

No chance of pictures - car too low and no ramp

I hate working on cars on the floor - lol :laugh:

Well it's impossible for us to help then without pics

is the exhaust held up properly? is if not movement in the exhaust can cause it to free itself gradually it may just be missing a rubber or off the hanger

Are you sure they're using a proper exhaust silicon and not just bodging it with exhaust paste?

Yawn.

You're asking why a joint keeps failing, it's very hard to say why without pictures.

Not sure about the 1.0, but the 1.2 has a close coupled cat on the manifold and the front exh pipe has a flange fixing to the bottom of the cat. Three bolts and a gasket - no sealant necessary. Is the 1.0 not similar and in need of a proper gasket?

Exhaust places often cut the pipe after the cat to fit an aftermarket replacement exhaust system. So the suspect joint could be after the cat - at least that's what I was figuring.

Hence the request for a photo - to see what exactly is going on.

OK - i'll get a picture
