Exhaust Tailpipe Nut....

Post by **T2Andy** » 09 Jun 2006, 14:56

Hi

Anyone know of the size and thread for the exhaust tailpipe for a 1.6TD, got to change the tailpipe (blooming great hole in it) and know I am going to have to cut or grind the nuts/bolts off. So wanna get the new ones before I start.

Thanks

Andy

Its M8 by 20, use stainless steel bolts then the buggers will come off again in the future. I have a used tailpipe, bit of surface rust but solid, yours for £5

standard steel bolts come out dead easy if you use brass nuts as should be used on all exhaust components

the tail pipe is held on by bolts only as there is a thread in the silencer box, no nuts are required just screw in the bolts through the tailpipe and into the silencer box, 3 required

I loosened some using this http://www.club80-90.co.uk/wiki/index.p ... bolt_punch

and drilled others out in situ... you might have trouble getting a grinder on the rear one. A few cheap (Silverline) cobalt drills are worth having, make it a lot easier http://www.club80-90.co.uk/wiki/index.p ... tuds/bolts

Have you still got this tailpipe? and if so would it fit a 1.6 non turbo diesel engine?? cheers

Think from quick try with the spanner going to have to drill, I have been plusgasing for the last couple of weeks, going away for the weekend, so next weekend, will be getting stuck into it, assume the black shround thingy round the silencer comes off easy enough to get better access or do you leave that on?

If thats the heat shield, should be silver/ally colour and is held by set screws into Rivnuts a few od which which'll probably shear off.

Try uisng a blunted off chisel as that tool I linked to - one of the finest ways of loosening nuts/bolts

- drive in and around, as described

A Turbo tailpipe will NOT fit a non turbo the turbo one is much wider

Yep looks as though it is a heat shield, but it is black? seems to be screwed to the rear bodywork in about four places and somewhere up tother side.

Have got a cheapish set of small chisels, will get on the grinder and give it a go first.

Thanks

Some of the turbo to manifold bolts are a bit special.. the main pipe is nominally 2" diameter.

Did this job at the weekend so thought I would post a follow up for information.

Removed the Black heatshield thing, was held on by 8mm Hexagon Flange Head self tapping bolts (x8)

Tried the tailpipe bolts with nice tight fitting socket and spanner, no chance.

Tried Harry's punch idea, got one of them moving, then snapped the head off, bit more Plus-Gas and got it out with the aid of a decent pair of long handle grips.

OK, to the remainding two. Cut off the bolt heads with a cutting disk in my Dremmel (Black and Decker copy), which then let me take the old tailpipe off.

More Plus-Gas and managed again to get one out with the grips, the other one was not budging, so cut it off flush with the Dremmel, ground it completely flush, then Centre punch, drilled out with 3mm, 5mm, then 6.8mm drills, pocked out what was left with a small screwdriver.

Then cleaned up the silencer flange and stuck on the new gasket and pipe, took just under two hours and about 8 pints of sweat.

Satisfying though
