So, the machine shop has gone through my block and low and behold, oil is
not seeping from the transverse oil gallery into the water jacket. They
pressurized the oil gallery to 70 PSI and it help pressure; nothing bleed
into the water jacket. Rather, the shop cooked out a bag full of sludge
from the water jacket in the back of the block. Apparently, the regular hot
tank dipping before didn't dislodge all this gunk, and the circulating
coolant would dissolve just enough to foul the coolant with the oily mess
that sure looked like fresh motor oil mixing with the coolant. Fooled me,
for sure. For good measure, we will coat the water jacket with some epoxy,
then rebuild the motor with Denis Welch pistons, street cam, bucket lifters,
hollow push rods and fly wheel. I am excited to experience how it will run
with the new DW parts to go with my DW oil pump I installed years ago.

Finally diving in to diagnose and fix the oil in the coolant. Hoping it's
just the head gasket, but since it started after the engine was done 11
years ago, I am suspicious that it's the oil gallery-water jacket wall
between number 4 and 5 cylinders seeping high pressure oil into the coolant.
Has anyone actually had or known anyone with this problem?
