[Healeys] Down pipes

[Tom Felts]

There are washers called Nordlock's that are good for this use.  I use them on the downpipes on my E-Type.  they hold.tom

Brass nuts are fairly soft so may be the split washers work there
 way into the flanges of the nuts thus loosening them up. You may
 try SS nuts or a steel washer between brass nut and spring washer.Another possibility is that the lock washer loses its tension
 because it gets to hot.I am not a lover of split lock washers anyway as they damage the
 surface of the nut and the item that is bolted down. I always
 prefer the smooth but slightly bent ones (don't know the proper
 name for them)

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,
Fred66 BJ8
