[Healeys] Fwd: Down pipes

[WILLIAM B LAWRENCE]

The rubber mounts shouldn't cause a problem, but the flexible sections of the down pipes may have become too stiff to flex, in which case the relative motion of the engine to the chassis may be transmitted to the down pipe flanges.

Also remember that heating the steel fasteners will tend to draw out the temper making them easier to stretch. If they have loosened before then they may have begun to stretch when you torqued them.

How are your rubber mounts? Is your exhaust rattling a lot?

I tried everything: new nuts, SS studs and torquing the snot out of the nuts (snapping a stud in the process) and still they would work loose.  Finally gave up and double-nutted with mild steel nuts with high-temp anti-seize on the studs; they haven’t loosened since.

Listers,

Today, I had to tighten the 6 nuts on my exhaust down pipes.  This is the second time in 2 years I have had to do this.  What is causing the nuts to work loose?  Each of the 6 studs from the exhaust manifolds has split lock washers and brass nuts on the down pipe flanges.  Each time time I have tightened the nuts, I tighten them until the nuts squeak.

What am I doing wrong and does anyone else have this issue?  What do I need to do to fix this?  The car is a 66 BJ8 with stock manifolds and down pipes.

Thanks for any advice, I'm stumped,

Fred
66 BJ8
