I have a 914 with fresh CIS 3.0 6 in it (less than 3k on rebuild). Due to travel etc I'm only driving it every 6 weeks or so. Every time I start it it smokes like crazy and some oil actually flows out of the tail pipe. Oil level is 2/3 of the way up between low and high marks. Took the air filter off to look for oil @ the air intake and did see a little as well as a small trickle of oil @ the top of the breather in the oil spout running back into the tank. Do I just need to keep the tank emptier?
If the car is driven 3 - 4 days in a row the symptoms go away
