engine wobble?

[locoboy]

Guys,

My 1998 406 2.1td is niggling me at the moment.

When driving alone at a constant speed say 60 in top and you let off the throttle, after a second or 2 you hit the throttle again you can feel the engine juddering a couple of times like the engine mounts are loose / worn.

It is eveident in lowergears but its more pronounced in top because the engine is working against a greater resistance.

I am lead to beleive that the engine has a dual mass flywheel, could this be at fault?

It makes no noise on drive take up, there is no slippage of the clutch at all.

I have wobbled the enigne back and forth and it does seem to move a fair bit but i dont know how much is 'normal' or 'acceptable'

Its done 135K miles and upon looking through the history i can see no evidence of a clutch change within the last 60K miles, or any engine mountings for that matter - surely they dont wear out do they? i have never had to change one one on a car before.

Thanks

As far as I know it was only the 110 HDi's that had the DMF.
Does sound like worn mount to me; top is the easiest to check, you have to remove the OS driveshaft to replace the bottom one!
