I have a 530i just recently removed intake manifold to change seals and the infamous "No Return Valve" and the leaking "O" rings. There was alot of oil in there I cleaned up most of it and vacumed it clean, but it still seems like its leaking, as there is fresh shiny oil puddles in the crevices and I can still smell it burninng when engine is hot. Did I miss something? Is there a gasket on that cover under the coolant lines?
Also, does anyone have any photo's of the Oil Filter housing from the side, probably with the engine out, as anyone who owns one of these, there no seeing anything around there unless you remove lots of stuff. It feels like theres one of those rectangular electrical connections - without a connection.
I didn't see the oil separator, all drawings say its there, I don't see it. The tube from the "No Return Vave" slides over a pipe that goes directly into the timing chain cover. The realoem.com drawing shows a pipe that comes up from the crankcase to the oil separator then elbows into the pipe that goes to the valve in the back. Is the separator in the cover or should I be able to see it on the outside running up the front of the engine? You guys don't think it could be that cover?
Are you talking about the rear intake cover, cause I thought this was called the "No Return Valve", otherwise I don't see anything that resembles the drawings of the oil separator. There is an extra line coming from that valve but it was just plugged.
I still think the oil sepage is coming from that center cover, under the coolant pipes. Have any of you guys removed that and replaced the gasket and what does it cover?
