Change exhaust manifold 182

[mark31]

My manifold is knackered (flange where it bolts up to the cat is rotten). I'm replacing it with a used stock one. I've heard that changing the manifold is a bit of a b*tch of a job - can anyone who has done this can confirm that is the case...?

Cheers,

Bit of pain...

you will need to drop the subframe to remove the manifold!

 

[sideways danny]

yes. yes it is a "bit" of a pain.....

I've done it the other day and i need to say I expected it to be a lot worse from what i read. I also need to point out I was doing it by myself in front of my house I dont think you need to drop the frame to remove it it's getting the new one in that requires to dropping it.

Are you talking about a 172 manifold?

Make sure it is the actual manifold that is rotten and not the "cups" that the spring bolt heads sit in. I made this mistake and started pricing up a manifold before I took it apart and figured how it all fit together.

I was changing the 172 to a 182 one

I should have mentioned it's a straight swap - one 182 manifold for another, on a 182. Sounds like putting the 182 manifold onto a 172 is a bit of a pain - but will I need to drop the subframe to do this if it's a 182?

[Adam-o]

its pretty much the same thing, and yes you will need to drop the subframe

 

[mark31]

Glad I checked then - pretty sure tech manual makes no mention of dropping the subframe at all!.

How long did it take you?

Cheers Adam.

you sure its not just needing a new fitting kit?

pictures?

 

[Adam-o]

well it took me a few hours, hard to say exactly as i was doing a few things at the time, but as Fred said are you sure you don't just need a fitting kit? there was some rust on mine aswell but nothing to worry about tbh

 

[Rudda]

did you lads take the subframe off completely or just hang it on the balljoints? Changing my 172 mani to a 182 mani on saturday? Cheers.

 

[Fred@BTM]

^yeah its easier

I followed the guide on here, took probably 4 hours as it's the first time I'd done it and I wrapped the manifold. I dropped the subframe pretty much down to the floor whilst the car was on axle stands, makes it a LOT easier; just watch for any cables/pipes (e.g. brakes/PAS) being stressed when the subframe drops. The guide on here was written very well and the photos show you exactly what you need to remove. Make sure you get a fitting kit and a new exhaust manifold gasket. Also be aware that the 182 manifold is a lot 'longer' than the 172 one, therefore you'll need a 182 -> 172 link pipe/decat (or sports cat) to link it to your 172 system. Don't expect the 182 manifold to link straight to your 172 center section!
