Exhaust touch point on the chassis,
spiggot bearing worn allowing the clutch plate to run off-centre,
worn bearings in the gearbox,
fan blade missing, ( once saw one that had gone up INTO the bonnet after
shearing off...)
Water pump bearings worn,( rock the fan...expensive,)
First signs of worn main bearings.....is the oil pressure good with a
very hot engine, at idle?
You say you have fitted a new engine mounting? Often the modern rubber
is very HARD, and simply transmits more vibration, very true of the
front one. The old rubber was probably very soggy, absorbing it.
Is the gearbox sitting on its cross-tube, again touching the chassis?
New mountings needed if so.
Is the gearbox steady still there? A tiny eye-bolt facing down, with a
nut, a steel cup, and a RUBBER WASHER, to stop the gearbox lifting.
