10,000 miles and two years of driving in very cold weather and short trips. I never have to add any oil. There is not any mayonnaise type goop in the valve cover gasket!

I have a really bad idle in D and R (red lights). Smooth idle in park and neutral. Car seems to drive well. Usually use qt. of oil about 500-750 miles. I have done just about everything you can think of to this car except CCV. 2001 X5 3.0i and 187k miles. Do you think this could be my culprit? How are cars with modification? Are they all still ok? Are their any new updates?

Close to 70k with this mod with zero oil consumption. On two occasions the CEL came on with misfire codes. Both were vacuum leaks. One was from a plug that developed a crack in it. The other was from a piece of original CCV hose that developed a small crack. Easy fixes. Great mod!
