Hello,
I've git a 2.25 petrol with a 3 hole connection between the manifold and exhaust downpipe.
Its blowing at the joint, but I can't find whether or not there is a seal available or required for this joint.
Does anyone have experience of changing this type of exhaust and whether there is a seal required?

Many thanks.
 
As above, no seal required. I changed this, bolted right up taking care to tighten the nuts (get correct brass ones) evenly. Bear in mind depending on the age of the Landy there are two different versions of the nuts with imperial and metric threads. Getting the old one off was a faff as odd nuts (including a Nyloc!) had been used. Patience, winding the nut in and out a bit at a time, and copious quantities of Plusgas meant I got them all off OK.

I have a box of brass exhorst nuts in the garage somewhere ... :oops: still ...
