Took the car out for a couple of short drives over the weekend to get a feel for it...

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? The noise is pretty loud as the body acts like a soundbox!




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? There seems to be plenty of oil getting to the rockers.... and I cant see excessive wear anywhere...

you will always get a bit of diff whine, i get it but you soon blank it out.

don't know about rocker

Regarding the tappet clearances I would say unless it has been converted to use unleaded fuel leave the clearances at the upper limit to aid valve cooling.
