Cyclex super flow valves -- still issues?
« on: June 24, 2016, 05:29:23 PM »
I'm hoping to order a set of these this weekend, but I remember reading a thread about some coating flaking off of them, particularly after a few hundred miles or after lapping them in.

Is this still a problem? How have people got on whe them after a few years of running them? If I take them to an engine shop, do I need to give them special instructions not to lap them, or are they just like other valves?

I used hundreds with no problems. And there wasn't a problem to begin with.

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis

I put them in the cyl head of my F2 a few years ago along with new guides, I can't confirm or deny whether any coating has flaked off because I haven't had it apart since then to find out and the reason I haven't had it apart is because it still runs great so I haven't had a reason to take it apart in the first place.
