Nightmare trying to remove CAT / DECAT

[Realnut]

As we all know the two 10mm bolts that join the cat to the manifold are are a right pig, but I got mine up on the ramps today to swap the cat out and and ended up not changing it due to 1 of the bolts having been overtightened in the past meaning that the washer that holds the spring in place had been pushed down the unthreaded shaft of the bolt, nothing I could do would shift it so and as you'll know there aint much access to it so I'm kind of stuck now (

Haven't even put the nut back on the bolt as the washer is keeping the spring bolt tight, hoping it just snaps during daily use so I can actually get the job done.

Proper angry now like, after 3 hours on my back with rust in my eyes :dead:

Horrible job, worse without ramps

Aye it's a terrible job
Only thing you'll be able to do really is see if you can get a dremmel with a cutting disc on up there and cut it off

Honestly it's just not worth the hassle - bit more noise and less power. I wouldn't decat a clio again

 

[Realnut]

Yeah I was thinking dremmel too or a long thin saw of some type, I'm actually putting the CAT back in as I want it back to standard.

Its not the same as a 182 cat, 1 hour on a 182 i would say is pretty slow lol

if you pull out the motor and gearbox its a doddle to get to !

182 cat = 10 min job

172 cat = 2-3 hour job

or if you hold a spanner on the stud from under the bonnet, get the missus to get on her back under the car and undo the nut. Simples

Did you read the original post? The nut comes off but the washer has been pushed down the shaft and is wedged solid

 

[Realnut]

I've given up and booked it into Maltech in Stockton, let him have the headache lol (I have pre warned him of the fun he will have)

 

[bengtt5]

leave the nut on loossely and hit it
or with the nuts off yank it side to side
or thirdly stop being a blouse and man up

 

[Realnut]

Tried all that (and more) Believe me, if I had hit it any harder it would have taken the manifold off!! I was amazed how much crowbar/hammer action it took and wouldn't shift. Despite lying underneath I could get quite a good swing at it but still no luck. Still driving round with the nut off and no sign of it shifting any time soon...

I got my 172 decat fitted for £30, garage quoted not knowing the job is a PITA lol

Lol, I done that too on my first one, haha!

182 cat = 10 min job

172 cat = 2-3 hour job

Can you expand on this please mate?

I assume it's because the 182 has a different manifold?

Is the cat the same part on a 172 and 182?
