Well, looks like I'll be pulling valve covers to get a look. I did some tuning yesterday and got the no load parts of my VE map running fairly good. I stopped it and let is set for a few minutes, then restarted it and got a visit from the blue Genie. It's only 5 bolts on one side, but I have to remove the fuel pressure reg to see the other side. At least it doesn't knock and has good
oil pressure.
