Noises and things

[tegwin]

As fortune would have it, the car was finished and MOTd for the first sunny weekend of spring

Did about 20 miles just making sure everything works ok...

Two annoying noises though..

Firstly, the diff makes a honky type whining noise under gentle acceleration but only at specific speeds/engine revs. I had the diff out of the car and inspected it when I rebuild the back end... everything looked ok, there is some backlash, but nothing untowards.....

Is this noise normal?




Secondly, the rocker gear in the triumph engine seem to be excesivley noisy.... I adjusted the clearences to the higher end of what is recomended in the owners guide....

Would closing up the gaps a smidgen reduce the noise?

When rebuilding the engine, was the head skimmed?

The SAH stage 2 head I fitted to my 2500M some 30 years ago required shorter pushrods to avoid contact with the rocker cover.

I dont know I am afraid, I didnt rebuild the engine.... was done a few years ago by the previous owner..

Just checked the valve clearences and they were a bit loose... tightened them up a bit and it seems a little quieter... the gap in the exhaust where the headers meet the exhaust might be exasporating the noise... Will plug theat up and see if it makes the valve noise a bit quieter....

Still not so sure about the diff though!
