My Ride: E46 330d Touring
Injector studs snapped

Car is an m57 330d, the manual non swirl flapped 184bhp engine.

For some reason one of my injectors decided it wanted to break free while boosting and I'm now left with two cracked injector studs.

I'm pretty sure it's part no. 3 in this diagram: http://www.realoem.com/bmw/enUS/show...diagId=11_2314

I've removed the injector and fortunately there's enough stud protruding that I could undo the 10mm nut that holds it in place on the rocker cover. With that loosened, I then go to pull it out and it rises about 10mm or so before not getting any further. It's very loose and from the image in the link above it looks like it should just pull right out, but is that not the case? I don't want to pull too hard for risk of damaging anything.

Any help would be massively appreciated!

Couldn't find any info so just went for it.

For anyone who ever encounters this problem, the whole insert pulls out of the rocker cover with a bit of force after unscrewing the stud from the head.
