The title pretty much says it all, I'll be doing a VCG replacement soon. I've never done this job before but I've seen some very helpful tutorials on YouTube for it. I'll probably replace spark plugs while I'm in there, is there anything else that I should do during this job? The previous owner did a Vanos seal and anti-rattle kit about 25,000 miles ago.
I also should probably mention that the reason I am doing this is that I have oil residue on the front and passenger side of the engine block. I plan to do this as well as a cooling refresh that I've been saving, clean my engine bay of the oil residue, get it all buttoned back up and hope that the oil leak is solved. Thanks for the help!
