My BMW X1 2011 have done only 45k and its rocker head cover gaskit / seal was cracked and leaking oil. Never expected this from BMW. Later I have come to know that its common problem with BMW. The plastic cover is also de-shaped a little. My mechanic have fixed a later model with the same issue. Why BMW don't make covers from a high temp resistant material? I have seen BMW running in +40 degree heat of Middle East but temperature in New Zealand are much lower then other hot countries.
