Followed this DIY tonight and I sandwiched in the Oil Housing Gasket DIY (
http://www.e90post.com/forums/showthread.php?t=632565) in between Step 8 and 9. Every step is accurate and the write up was definitely descriptive enough. Took me about 3 hours for both DIYs. Thanks to everyone for all their input.
Looking back, I should of done the flush again because I DID have the rubber particles when I drained the radiator. I expected it and that's why I did the oil housing gasket replacement.
Performed at 61k miles.
