Well you may be over thinking it but you are at least keeping us amused :-)
BTW the BN1, BN2 and 100S didn't have the "O" ring seal so I think in their
cases the gasket was the seal..
Pooffff goes that theory..

>=C2=A0 This is, I believe, the only place on a Healey where 'conica=

>=C2=A0 are used.<br>
>=C2=A0 It has been my experience that conical seat nuts always require =
re-torquing<br>
>=C2=A0 after a little=C2=A0 use. Just like the lug nuts on your every d=
ay driver if<br>
>=C2=A0 you torque them up, then drive the car for a bit you will find t=

>=C2=A0 nuts will take up to half a turn just to restore them to the ori=
ginal<br>

><br>
><br>
>=C2=A0 That said however I do have to agree with Chris regarding aggres=

>=C2=A0 On AHX12 we found it necessary to re-torque those nuts after eve=
