chris525i 2 Report post Posted March 22, 2017 Hi everyone. So I changed the spark plugs on my e60 530i over the weekend. The old ones were filthy and I noticed a fair bit of all around the plug for the cylinder closest to the back on the car, which I believe is valve cover gasket?? After 2 days the check engine light has come on, car is not running poorly but am concerned as to what it could be. Does anyone have idea of most likely cause? Also does anyone know a good/cheap place to pick up a code scanner from? Thanks in advance. Quote Share this post Link to post Share on other sites
