Omaga squirts after start and idle phases

Hello together, since a few weeks my Omaga shows the following behavior If he has stood for some time (1 to 2 hours) or after a longer idle phase on the highway he squirts strongly (Oel) When driving he feels normal. Cylinder head seal or piston rings would rule out the oil somehow also have to come into the combs at a standstill I guess it comes out of the intake tract because it is especially the first correct gas giving after the start n especially heavily squalid Have you got an idea Gruss Jerry PS I wrote the text on a Croatian keyboard on vacation Special characters are hard to find grins
