Hi all, new to the forums but have had my 2001 525i Sportwagen for about 7 years now. I rebuilt the engine about 2 years ago but have recently found that there is a leak from my valve cover area (rear passenger side). I did the gasket back then like anyone would but have heard that the valve cover itself can develop hairline cracks over time, and having 175k miles on my beamer I am expecting that that is the issue. Has anyone else had this issue? And do you recommend buying from the dealer or are there good quality valve covers elsewhere? I’m sure the dealer is going to be expensive and this isn’t exactly a wear item so I’m not concerned with going aftermarket for this. Thanks for you help!
