All the stories of
oil quality going south, and part quality not being what it should, my next build will employ a roller cam. It's very sad. Breaking in a cam has always been a scary part of building an engine, we certainly don't need more head aches. Technology should make this stuff easier, but it's technology that's making it harder. OEM's are all using roller cams for this very reason (as well as other reasons), fewer warrenty claims are probably a big part of the story.
