My diesel does the same until it's warm, Changed the engine oil last night, and now it goes away a LOT quicker. seems like the same issue the petrol boxers have where (as far as I know) the pneumatic cam followers are expanded by oil pressure get a bit stuck and don't open fully. I was able to fix this years ago with a new oil pump and 2 successive oil changes - essentially a flush. - don't forget to reset the oil dilution ratio
