Subject: Re: Exhaust Manifold Gasket
I apologise for the late reply Laurence - we took a short holiday to recover from the short holiday. I'm sorry the evil orages caught up with you - we somehow ran between them though had the hood not been up (which I hate) I'm sure we would have been also soaked under Dr Sodde's Universal Law.
I think I described the gasket condition poorly. There are no cracks or tears but plenty of soot marks on both sides marking the blow. Nothing I could call a burn though. All the evidence is that the brass nuts just kept on loosening off, something I've never encountered before.
I didn't try your Redex ploy as having got home I just charged in and removed the manifold. Great idea though.
My thanks to Colin and Hugo for excellent ideas but I think now that the problem is simply brass nuts refusing to stay tight. As yet, I don't have a cure for this. Something called a Nord-Lock washer has been suggested to me as being better than a spring washer but I've yet to investigate.

Thanks to all for the help,

John
