Would you risk it? What would you do?
I had Crower camsavers fail. They didn't fail to break in or wipe lifters and lobes. They failed to pump up when hot and the engine sounded like it had solids when warmed up. I snatched them boosheet lifters out and put a set of the cheapest Melling lifters Summit had in stock in it and it's been running great ever since. Over two years. And come to find out, all of Melling's engine parts are made in USA. I also very recently used Melling cam and lifters in a Chevy 283 I built for a friend's father in law and it broke in and did fine.
