In one of the old posts ( which I now cannot find) someone mentioned that they were getting a slight knock and was told that if the van ( mine's a water cooled DG) is standing for a while the push rod tubes ( their words not mine) stick a little "but after a good run they clear" is this true Iv'e had that happen to me. The slight knocking seemed to come from the head end of one of the cylinders.

The hydraulic valve lifters (that push the push rods) can drain down of oil if the engine hasn't been run for a while.
When you start it you then get a knocking till the lifters "pump up" again.
Fairly common, can take a few seconds or 10 mins depending on how badly they have drained down.

Thank you MM now I will not worry, the problem has not ocured again since I use the van more regularly.
