My camshaft seems to drift back and forward excessively. To the tune of .200" approx.
What is this play supposed to be, or what works.
I have had everyone say my camshaft looks like it is sloppy and strangely deteriorated at the side faces of the lobes. Like it has been thrown back and forth down that alley of mean solid lifters way too abusively, and hence seeming to chip away as the edges of lifters vs. lobes will overlap and grind past each other in the cam's over ambitiously long travels fore to aft of my Cam Bearing Tunnel.
(Slides front to back too much)
I will probably just order a new thrust plate... Seems to have the same play with either side of the plate. One side appears worn slightly. Though they seem to both be too much... How much is too much? My cam looks abused and I feel sorry for it. I'd like to give it a better working environment so it can maintain to be a happy and reliable Employee of my Power Plant.
I have a wool cushion spacer (Same material as the "Never Used" Oil Slinger Cushion) so I put it in there to take up the slack... And that it did. I felt it compress for some while as I Torqued down the Cam-Thrust Plate to spec. Worried it is under too much load/ loading the cam too much. Can't remember what type of surface limits camshaft play to the Rear. I believe it is a Special Style "Freeze Plug" type soft metal instert that is hammered flat as to press it in place to hold for such load bearing properties... As say cam thrust.
Now would this excess play detrimentally effect say, my Timing Advancement in a seemingly chaotic and unpredictable variance as the pinion gears slide along eachother too much in their rotation?! I can not recreate this slack with engine off due to valvetrain load on the camshaft, but I assume that while rotating could easily spiral through its Kaliedescope of lifters easily enough to become a rouge variable in the distributors proper alignment through all of its synchronistic advancment adjustments.
*Thinks "Wow I sound like an pompus asshole right now"*
However Minute this distance may be in the grand scheme of things, like I said it is about .200" or nearly 1/4 of an inch. And I am curious to know what this science is all about if there is one. Or if it is completely insignificant due to automated vacuum correction... ?!
-Dang curious anyways fellas,
