Thanks to the kindness of strangers, I have a 1977 series 2 XK6 engine sitting in my garage. I’m slowly stripping it of unneeded parts for my eventual kit car build, and learning as I go. I thought I’d start my own thread to post questions as they arise.
First question. Looks like there was a hose and duct type system for emission controls. I removed a rail off the top of the motor and there are now exposed threaded holes. Do these holes need to be plugged? I don’t know where they go, and I don’t want to damage the engine when I start cleaning it. I currently have 3/4 length 7/16 bolts in them to be on the safe side. Do I need to plug these up permanently with a shorter bolt and thread lock?
