manifold nuts

Post by **superchargedfool** » Sun Jan 11, 2009 9:32 pm

Has anyone else had the experience of manifold nuts coming loose?

I am running the brass type and have found recently that they are coming undone slightly after a few hundred miles.

I will probably change them for a steel locking type, but just wondered if others have had the same prob on modded or standard a series's

Brass are best! They may be badly worn - or the engine may have severe vibration. The long brass nuts are the best ones to have - they are about an inch long, and easier to get a spanner on too.

my dad has had this problem, its a standard 1275 engine with an alloy inlet manifold and a triple branch. he did not buy any new nuts though...so i wonder if it could have an effect as they could wear i suppose...but i would imagine someone of your building skills would have got new ones!

this has happened to me as well it was just worn nuts in my case as the ones that came loose had started to mushroom where they had been on & of several times in there life

You could possibly wire them together.

I find h/d lock washers work for me even though my nuts are worn

worn nuts is never good eh?

I might try new brass ones before looking at other options then.
