Well, it was a fine party late last night, what with me, johnpro, and SAC69 disassembling the 289 and changing the cam, among other things. As John was removing the timing chain gear at the front of the cam, here comes the cam with it! "Well, hey, where's the thrust plate!?!?" said John.
Sure enough, it's not there, no plate, no gasket, no bolts. (Gee, that explains the rattling noise I heard in that area. I always thought it was the water pump getting ready to go. /forums/images/icons/tongue.gif) A check of the inside of the timing cover showed scratches where the front of the eccentric had walked up to it. The cam lobes also showed wear to the side of the lobe, further indicating that the cam had grown legs.
The interesting part is that the cam looked original, and had the proper casting letters on it. So, why would anyone have ever removed the thrust plate? It's a weird one...
BTW, I now need a thrust plate for a '68 289. /forums/images/icons/frown.gif
