I've been having some problems with components in the valve train on my L84. The engine was supposedly rebuilt close to stock, with an aftermarket version of the 097 cam. Since I know only enough about the subject to be dangerous, I've been reading up in the archives and elsewhere on line, to try and gain a better idea of what might be causing the problems.
I found two issues I'm concerned about. They might be critical, or, of little importance, I haven't got any idea:
The first, is about the spring retainer: I read that "the retainer must fit tightly into the spring". Mine are very loose. Does that really matter? If so, what problems do ill fitting retainers cause and how do i find proper ones?
The second: The valve springs in my engine are of unknown origin, They are similar in free height, but almost 50% stronger than new Sealed Power VS-677 springs (that are supposedly identical to the originals in the L84 engine) that I had tested.
Can pulled rocker studs (and a broken push-rod after the studs were screwed in) be caused by either of these issues?
Thanks, Mike
