Guys, I stripped the hell out of a head bolt on my Avenir taking the head off today. Has anyone does this before? What was your solution? I'm going to get a larger sized Hex bit, pound it into the head, and then weld the thing in. Anyone else try this???? Secondly, could anyone check the price (easily, I'll call a dealership later) for the Nissan valve shimming kit for the SR? Part number is: J38957 The head is going to the porter as soon as I can get this last stud out. Yep, stripped the last ****ing head bolt. On the related subject of my W11 Avenir motor that I bought from JGY about 2 years ago now. This motor has VERY VERY little miles on this thing. The intake ports were clean, no soot, nothing. If you are too take your nail to your exhaust ports and scrape a little soot off of the exhaust side you see SHINY metal. This motor has very, very, very little mileage on it. When it was leakdown tested, it was 5 to 8 on each cylinder. Long live JGY.
