Interesting. I did not know that. Got a link handy that explains blocking the ports and cutting gaskets?

I found some videos on it. I also see that Dorman sells an "Updated and better" VLOM. I wonder if I just pull the old VLOM out, put a new in, put a new oil pressure sensor screen and new sensor and try it, if will allow everything to work then run the AFM disabler or have it tuned off.
