I?ve read the archives and understand that the early Volvo?s suffered from excessive cam wear and that the DeLorean version uses hardened cams and therefore don?t have the same problem. My passenger cam used to have a loud ticking noise until I adjusted the rocker arms and I was surprised at how much quieter the engine was. That was 6 months ago, and recently the engine redeveloped the ticking noise and I adjusted again. Less than a month later it is back and getting louder. I?m pretty sure that this is indicating that I?m experiencing excessive wear. The cam is well saturated with oil when I remove the cover so I?m wondering what might be causing the cam to wear so badly so that I can fix the cause when I replace the cam. Are there a set of causes that could make the cam wear or is this a case of the cam being damaged in the past and just needs to be replaced, nothing else? Thanks!
