Well today my other Riva IC sprung a leak and this time it took out number 3 piston with a major failure. Is there any way to know this is happening before its to late or just go Gen 2 or Pirahana? It was running harder than heck started to sputter and WHAM total lock up . Is this common? I see its known issue and I even checked it out for leaks, I guess thats only good for the actual time its being checked . Anyone else have this issue with a major failure?
