I just replaced the OFHG. When I removed the housing some oil dripped out, I followed the DIY exactly. I still have drips. I cleaned everything up pretty good. SO, I am not sure if I am leaking from a new place or if the oil that spilled is still falling off engine parts. I cleaned it up again, I will wait 1 week and see if there are new puddles. Anything to check out. I also replace my VCG about 8 months ago.
