Camshaft 'slip'
Hi
I'm very slowly re conditioning a 1990 3TB...
I think this is obvious, but I'd like a second opinion before I rip into it....
I have the rocker cover off cleaning and replacing things, and now when I line it up for sealing (lobes down, I mark, piston at top) if I rotate it anti clockwise it feels like is jumps a gear on the timing chain on the bottom cog. When I check it, it's out of alignment again. If I rotate clockwise, no jumping.
It feels like a worn driven gear at the bottom of the cam chain (I don't know the proper name for the gear sorry) - surely it shouldn't jump a tooth no matter which direction you rotate?
Does it sound like an inspect and replace?
Opinions grateful...
Thanks
Jim
