Exhaust sealing
« on: 22 October, 2017, 17:38:00 »
I'm sure it must be on this site somewhere but does anyone know the best way to seal a push in exhaust on my B31? Thanks

I use PTFE tape and exhaust paste on my A10. Seals well and comes off OK. Have also used PTFE tape and high temperature Loctite 5920 (copper) also works OK.

Is it necessary? I recently took my exhaust off, no sign of sealant, put it back together without it as well. By the way, couldn't see any purpose in the finned rose at the entrance to the cylinder - it's just held on with a kind of clip, appears to serve no purpose other than look nice. Phil (novice)

I think that the idea of the finned rose is to help to cool the exhaust pipe and minimise discolouration of the pipe. Some people used to wrap copper wire around the pipe instead. Don't know if either method helped at all.

Sealant needed or not will depend on the individual fit of the exhaust pipe into the head. It cannot be generaised.

The rose also improves appearance

My engineering view is that the rose serves absolutely no purpose other than cosmetic. My B40 is fitted with a rose but my B40WD is not.

Standard bathroom silicone sealant has worked for me.
