Hi guys
Worked on the 560 a little tonight. Dropped the oil pan and
took out the oil pump. The pan had about a half inch of sludge
in the bottom and the pump filter did need cleaned out. Check
the main and rod bearings and the were all within clearance.
The rods were between .0015 and .002. The mains were right
around .002. Checked all the piston skirts and they looked to
be in tack.
I was a little more curious about the tappet knock against the
cam. A few weeks ago when I was adjusting the valves I
noticed that two of the push rods were kinda messed up. The
tops of them had been egg shaped or at least not true like the
other ones. The adjustments on the rocker arms were also
messes up. Instead of being rounded on the bottom, they were
flattened. I had a parts tractor here, so I changed the bad ones
out. What would cause something like that. Is there a fix for
the tappets knocking or at least something I could look for to
identify the bad one.
Thanks for the help.
