I'm otay. You are not.
I think it's time to give the 540i a nice engine cleaning. It's not too bad, but after seeing some underhood photos on this forum, I'm feeling a little guilty. I've not done this before and was wondering if anyone had some good horror stories about getting something wet that they wish they hadn't. Or stories with a happy ending... like how they did it quick and easy (hopefully). What works good, what doesn't, etc. Thanks in advance!
