Does A Blowing Exhaust Fail MOT And Why?

If it's a "significantly large" hole it will fail, otherwise it won't/shouldn't. It's to do with gases going up into the car as much as anything.

Chance of fumes in the car and emission failure

Wiggy ( snipped-for-privacy@hotmail.com) gurgled happily, sounding much like they were saying :

Yes.

No, it's because if it's blowing it's either not fitted correctly or it's falling apart.

Yes it will fail. THe only place exhaust gases are allowed to come out=20 is the end of the tailpipe.

It hasn't to do with the noise. The tester will block off the end of=20 the tailpipe and hear the hiss.

I'm really a nice guy. If I had friends, they would tell you.

The message from Conor contains these words:

That's not strictly true. Some exhausts have small holes drilled in them to allow condensation to drain. Exhaust comes out of these and that's OK.

Note: A minor exhaust leak from, for example, a connection joint or a pin hole, is not a Reason for Rejection

Are you allowed to put aluminium tape over a hole? Mine has a small hole, it makes a nice noise I like my hole. But MOT next month. :(

Number of times I've pasted that URL in here...

and if your that bored you can also view on-line all the special notices we get sent.

So who's volunteering to assemble an FAQ for this NG?

The message from "reg" contains these words:

F*ck but it's rivetting!

Chris Bolus ( snipped-for-privacy@RILEYELFb0lus.com) gurgled happily, sounding much like they were saying :

I think you just did.

Has anybody EVER read a NG FAQ?

Guy King ( snipped-for-privacy@zetnet.co.uk) gurgled happily, sounding much like they were saying :

Sad but true.

Bookmarked.

uk.d-i-y is very good.

I'm tempted but it wouldn't be a one man job. I'd need the 'experts' to write their bits up once and for all.... I'd just dump it on a website somewhere.

Hah! No.

uk.music.guitar used to have a very good one until its maintainer retired.

Here too..
