    BMW E53 X5 oil leaks

    Hi, I have a 2001 BMW E53 X5 4.4i sport and it keeps having huge oil leaks. It was running perfectly before I had an oil change, air filter replaced and oil filter replaced by my mechanic. First huge amounts of oil squirted out of the oil cap so i had it replaced, then huge amounts of oil squirted out of the crankshaft seal so i had it replaced. Now there's another oil leak but i don't know what's broken this time yet. All this happened within a couple of weeks so there has to be an issue. too high oil pressure? If so why is this happening? Thanks for the help.

    I own a '05 E53. Last week it had a huge oil leak on the right side of the valve cover. It occured after starting 1st thing in the morning (the outside temp was 6°F). Root cause was a frozen CCV valve causing high pressure in the crankcase.

    Hi, still looking at this thread? Did you buy the cold weather ccv valve kit when you replaced it? I have cold winters also and have the same car.
