Alright, so my buddy's friend has a Bmw 528e for sale,
And it needs some fixin.
There is a fuel leak in the engine, we need to get a intake manifold gasket, and we're pretty sure the leak is from the fuel rail or possibly injectors...
Looks like we need to take off the intake manifold to take a closer look at that leak.
Anyone had similar problems?
New to bmw's and this forum.
Any help would be awesome.

You can remove the injector rail without pulling the intake manifold. Remove the fuel lines at either end and the 2 10mm bolts that hold the rail to the manifold. The valve cover should be removed for easier access. Be sure to replace the valve cover gasket and the rubber rocker shaft end plugs. It would be a great idea to check/adjust valve clearances at the same time. Might as well replace all the injector O-rings (upper & lower) when you have the rail out.
