All good info above.

Worth noting; there are four spots on the rear side of each VCG that MUST have a small bead of RTV sealant applied (the corners adjacent radius areas). When this is not done, they leak.

Details like this make the VCG job a must DIY. Also the common practice of techs yanking the injector harness wires to unplug, just watch BMW VCG DIYs on Youtube.

I cringe watching them!
