[Healeys] Down pipes

[Mirek Sharp]

As I recall, you don’t need the split washers.  The washers could be fatiguing with the extreme heat and losing their “spring” – just guessing.  Make sure  the rest of the exhaust system is properly secured.  I have never had an issue with them loosening and have always got them just really tight – never torqued them, though that sounds like a good idea.

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
