Exhaust Blowing - MOT

[Baldin0]

Had car in for service today and my milltek is blowing where the Cat joins the center section

How easy is this to fix? and can it fail an Mot?

 

[Russ_16v]

if its at the join then it prob needs a new gasket and yes if its blowing it should fail

 

[Dave..]

Theres no gasket at that joint, and it's the worst one to try and get to seal properly IMO.

I'd get a new clamp for it, undo the joint and clean off any paste/gum/crap, clamp it up with new clamp and seal with a silicone based sealant

I can testify to a blowing Miltek at that exact point causing it to fail its MOT :O(.

Theres no gasket just that stupid clamp! I put a good seal of high temp silocone sealent on it and around the clamp and it did the job! Seems to be holding well so far.

Shame that I can't say the same about the welds on my back boxes!!! They are blowing but at least Miltek are sending me out a new rear section.

Awww not what I wanted to hear. Least my welds on the back boxes are still going strong after about 8000 miles

Had same problem on my MOT there was a major air leak at the joint where the zorst meets the cat pipe, causing the emissions and Lambda readings to be way out - it is a temporary fix getting the exhaust resealed with paste as after time it will need to be resealed again.i had a new clamp fitted around 5 weeks ago with nylux bolts and the joint where the zorst meets the cat was sealed with a good dollop of paste - everythings still fine but i am keeping my eye on things !!

best of luck with the retest

I had a look at Clamps on GSF and there are 9 different ones
Anyone know what one it is I can get?

 

[Adamski182]

The part number is PGP55, its a factor timax part number - That info was supplied to me by the guys at Birchdown (Renault specialists in Cheshire) I am not sure of any online stockists though

Maybe they can order one in for you or advise of any retailers in your area ??

I used small tub of holts high temp sealant from the local motor spares shop - only cost about 4 quid - mines been fine for over a month now

i used a winter hack last year to save the bike from salt and it passed the MOT with a blowing exhaust. the tester said it was only an advisory as the car passed the emission test.......and that was at ATS where they could've easily failed it (as i was expecting) to get more money out of me for a new exhaust
