Exhaust bolts

Post by chriscburgess »

Can anyone please tell me what size and length bolt I need to bolt my exhaust to the manifold. I think they are M8 but have no idea what length and I have found two missing.

Also can I just use steel bolts or do I need something specialist?

Can I use Loctite to stop them falling out again?

Thanks

You must have missed this when you tried the wiki

so you'll need a 20 mm length

People usually have trouble getting them out - not them dropping out of their own accord!

Ah! thanks Kev. I did search the wiki first honest gov! but did not see that page.

What is odd is that I didn't have studs in there in the first place it was always bolts. Is that right? (it is after all an Elite engine!)

So would steel bolts with a washer do?

Bolts are better in my opinion, it means you don't need to split the system to get it off in the future, you can drop it as a complete unit. If you want to go specialist get tungsten bolts £££, or stainless, a coating of duralac or similar will hopefully prevent bimetalic corrosion. It's tight with the bends in the exhaust in the way but doable, I seemed to managed it.
