            style="font-size:12.0pt;font-family:"Trebuchet
            MS",sans-serif">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.<o:p></o:p></span></p>
