Exhaust manifold leak

Hi I have a 1982 bedford cf motorhome
wondered if anyone could help, I’ve got some smoke coming from where the exhaust joins to the manifold, I’ve looked in the Haynes manual and it says about a copper/asbestos ring/gasket, I’ve taken the the 2 bolts off from the flange and pulled exhaust from manifold but can’t seem to see any copper ring could it have disintegrated? Is there an alternative? And is there a temporary fix as in using some sort of sealer as I’m hoping to go away at the weekend
Thanks in advance

Alex , you can just use exhaust paste , make sure you bolt as tight as you can , make sure the down pipe has no play at the manifold , you can get a seal ring and try that in the future , but it should get you back on the road.

Copper/asbestos ring is for earlier models only.

Later manifold casting has a protruding conical seating for the flare of the front pipe.

For the later manifold use exhaust sealing paste as John says if the front pipe won't seal just by tightening the flange nuts.
