535i,intakeon the car, in less than 45 minutes. Your big issue is the #6intake
Hey Bill! This is exactly the question I had for ya today. I was up until midnight trying to figure out how to get to the intake manifold because there is a wiring harness and a fuel rail blocking the intake hex bolts. You're right, there is hardly any room to maneouvre in there. I couldn't locate the two 10 mm bolts - are these the ones closest to windshield? I separated the cylindrical object at the end of the fuel rail thinking it was the gas vapour ventilation return because it had a vacuum hose attached, but found out after slight fuel spillage that fuel was going through this! This can't be the fuel filter, can it? Anyway, I gave up because my baby was crying upstairs (room on top of the garage where I was working), rubbed on some Simple Green and off to bed. But I couldn't sleep and returned quietly to the car at 4 AM and spent two hours trying to find some type of connection that I could undo to remove the obstructions to the intake gaskets. So, from what I can gather I need to disconnect the fuel rail from the injectors first via the U-clip? And then how does the wiring harness go away? This is really the biggest obstacle...if I could get that damn harness off, I would be able to at least see all of the gaskets. Yes, you're right, #6 is completely hidden by the wiring inlet from the windshield side.
