What To Do With a Tweaked Flex Plate?

If it is bent the wrong way, it could put a load on the end of the crank, which will result in excessive end play on the thrust bearing. My 340 was like this when I pulled it down. The converter was bottoming out on the crank and I found .012" clearance on the thrust bearing, which should be about .007" max. Just get a new one, they are cheap.
