Lots of things to do

Exhaust looks OK...... |
Well, the exhaust didn't exactly fall off, but it started "fluffing", and I knew there was a problem. Back in post 0077 I had noted that there was a small crack in the exhaust, but it wasn't blowing at that stage, although I still intended to get it welded up. But over this past week I have driven the car quite a lot, and on Friday it was noticeably getting noisier. So over the weekend I took the cover panel off, and set to removing the muffler itself. Although annoying that it had to be done, I guess it was good for me to have to do it myself so that if it needs to be done at any other time during P2P, i know how to do it.

Once I had the two mounts undone, I could see the problem - the front mount was broken ! (There was also still a lot of red dirt caked
in around the mounts !!) The mounts used are Austin Healey Sprite exhaust mounts and are a hard rubber bushing sandwiched between two metal attachment plates, and are mounted in compression, not

shear, so there should be no problem. In this case the upper metal plate had just delaminated from the rubber. Over the weekend I experimented with the broken mount and tried wirelocking it as a way of preventing, or at least limiting, de-lamination of other mounts, and it seemed to work quite well - At least it would minimse the chance of mounts literally falling apart in future.
