Apparently, our friends at GM have a small issue with some of the LS7 engines. The needle bearings can fall out of the rocker arm. This is true for a VERY SMALL percentage of LS7's made in a specific time frame. However, on the better safe than sorry side, I checked mine, and sent them for a retrofit to a company that has a design fix, so it can no longer happen. If anyone has interest in knowing more, we can continue this thread, or you can visit the C6 corvette forum.

I just ran out to check my LS7 and I found out that somebody put my LNF back in!! Dammit!

I'm supposed to get it back tomorrow actually. Can't wait!!

But I'll end up driving it home and letting it sit until I get home on wednesday from Cadillac at my parents. But I just printed out 200 miles of MI twisties I'll be hitting up this week.

Thread hijack...

The rocker arm needle bearing issue isn't anything new for the LSx series motors. It has been an occasional reoccurring problem more or less since the LS1 went into production.
