Ok the dealer put a new head on my car last week because I cooked the original and now the dipstick keeps poping out? I searched and it seems like this happened to a few people, but there was never a fix mentioned. The car has 16k miles on it and never had this happen until the head change. I don't see a PCV or anytrhing on our cars either.

 

According to what a local dealer told me, the oil filler cap is vented on the 2.0. I asked if I could interchanged the oil cap from a 2.0 with a 2.2 and they said no b/c the 2.0 has a vented cap and the 2.2 is not vented.
