Hi,

I have recently sold my EFI disco for a low mileage '91 RR with the notorious/legendary (delete as appropriate!) 2.5 VM TD.

I have been making good progress re-commissioning the truck but have run out of ideas to solve the problem of excessive engine vibration, especially at tick over.

I think I have a good example of the VM engine as have paperwork of a rebuild at an established VM specialist along with receipt for the all important re-tourqe of the head bolts ect. Engines done 74k since the rebuild back in '97!
Runs well with fairly decent power, good mpg, warms up quickly and temps where should be.

The problem is as mentioned the vibration at tick over is definitely excessive. I have fitted new engine mounts, transmission mounts all seem to be ok and treated it to a new exhaust system as someone decided to attempt welding the down pipe to the centre box instead of fitting the required olive!

But has made little to no difference, the bolts holding the engine mount brackets were slightly loose when I came to change the mounts, so I guess something must be out of true in the engine?

Anyone experienced this or have any suggestions? I can't live with it to be honest, but don't want to do an engine swap as besides the financial issue I am confident the engine has a good few years left in it.

Thanks,

Keith
