On my P4 75 (1957), there is a bit of judder when taking off. By taking great care I can avoid it. The front engine mounts look OK. I have not yet looked at the rear one or the midway propshafy holder bush , can the latter cause judder if worn?

Judder is usually due to oil contamination of the pressure and driven plate. It can be cleared sometimes by slipping the clutch. It is well worth checking the rear engine mount under the gearbox as these go soggy, The clutch linkage can also have stiff or slack spots. A combination of all these can make clutch lining contamination worse.

In the end, the clutch and the source of the oil leak will have to be rectified by removal of the gearbox

The clutch linkage is OK, I checked it The rear mount might be the culprit , it felt a bit soft but having never seen a new one I don't know , It isnt a soggy mess though. I will get a new one and have it installed. Again the transmission support rubbers are OK but one day will need new ones. Thanks
