Hi guys, A Riviera guy recently had issues with stock rockers rubbing on the outter edge of some retainers.
The parts he has on the car are cam, 105# springs, retainers etc and he's been hearing noise. Further inspection found the rockers rubbing on the retainers.
Left is a new Intenese retainer, right is the now used ZZP retainer.
He mentions having to file the retainers to get the valve locks out to swap them. In contacting ZZP, they stated to him that there is nothing wrong and that these are the same retainers they have been selling. Odd issue though, another Riviera guy purchased the ZZP retainers, started to notice an issue and didn't use them.
Here's the full thread.
ticking noise, scuffed valve spring retainers
Just wanted to toss an FYI out in case anyone picks up ZZP retainers and things don't appear to fit properly.
Joe: They aren't answering his calls and only replied to his emails that there is not a problem with the retainer.
