106 burning oil

[craneman160]

pug 106 1.5d burning vast amounts of oil. Recent cambelt fitted,sailed through mot emmisions. starts and runs well, but has a tendency to cut out after a long run at high speed, when decelerating. Only signs of smoke when accelerating hard

Sounds like your piston rings are on the way out. The oil is seeping past them into the compression chambers at higher pressures; when your accelerating hard or at high revs. This will soon happen even at low revs as the rings continue to degrade. To delay it as much as possible keep the revs as low as possible and accelerate slowly. They already need changing though.
All assuming I'm correct in my diagnosis of course.

Thanks Skids

Had my suspicitions, just clutching at straws.

80000 miles on a diesel, must have been hammered, will have to bite the bullet and strip it.
