Thanks Bob,
Thats a good idea as well. I'll keep that in mind as an additional
post-reassembly thing to try if I still have a problem after drilling the
lifters. They aren't really all that hard to drill. I've drilled a few in
the past when I was replacing one or two pitted ones of an old set. You set
the lifter on its side on a block of wood, set a punch in the desired spot
and tap hard enough to make a pit. Set the lifter in a wooden V-block and
head for the drill press. They drill rather easily, then I clean the hole
with a hand twist of a larger bit to de-burr the surface. Check fit to a
tappet bore and be prepared for a light touch of a fine points file if there
is any binding from deformation at the drill hole.
What and where are these "two drain holes" you refer to? The pushrod holes
in the block start small, and have a tappet size counter bore. I've never
noticed any other path for rocker oil than to drain into the pushrod holes
in the head and thence into/around the tappets. Are there other paths I've
never seen?
Thanks,
Glen
