Catalytic Converter bolts

Post by steve747 »

Hi
I have just ordered a new Catalytic Converter but im stuck on the size of the 4 bolts to the manifold..
Do i need to use joing exhaust sealent between the cat and the manifold, or just the gasket..
Also the mot failed on the dust cover for the wishbone, can i get the rubber with 2 small tyewraps, or do they have to steel rings..



Thanks
Steve :)

Not bolts, they are M8x125 studs and "nuts with base", according to the Service Box Documentation. The Repair Procedures do not mention using sealant.

You might like to get the documentation for yourself - see this post.

Do not use sealant before the cat ... after is fine. If a bit comes loose and ends up in the cat it could cause problems.

No, the studs and nuts are what attaches the top flat plate. When you take the old one off, the studs should stay in the manifold.

I don't know why you keep talking about bolts - the manifold and the flange above the gasket are joined by studs and nuts. If you need to replace them, they would best be bought from a Peugeot dealer. The Part Numbers are dependent on when the car was built - if you want to know, post the last eight digits of the VIN.
