Hhmm... does it only do it upon startup then goes away? Usually blue smoke indicates burning oil. I think its white for water and black for when its running too rich.

When you rev the accelerator does it still do the same?

Intermittent blue smoke is indicative of oil burning, which is indicative of an oil separator failure in the culmination. Start digging in and see if you have a broken seal....or if the oil seperator went.


Comb through this thread also....as it may help.
