That's why I was wondering if just the injection pump can jump
and still have the cam in the original timing. cause the
compression is good. The timing device breaking is something I
will tell them to check, Though that will require the removal of
the front cover. I think. Maybe just do a drip timing check to
see where it is.

IF the timing chain skips a tooth onthe cam, I think the camshaft and
the bearings break. Certainly if it is off 2 or more teeth, the
camshaft will become several.

A friend has an 82 300D which suddenly lost power while going down the
road at 55-60. Blew white smoke and died. Supposedly no odd noises.
Won't start lots of white smoke coming out the tailpipe that smells
like unburned diesel. He did a compression check and says it's OK. I
forgot to ask what exactly it is. He has replaced all the fuel filters
and bled the injectors. Get fuel with no bubbles when the lines are
opened while trying to start. Says the fuse on the glow plugs is good.
What gets me is the sudden loss of power running down the road.
Only thing I can think of is the timing chain but I would think that
that would mess up the valves and effect the compression. Can the
injection pump jump timing by itself without the valves timing jumping?
Any clues?
