no, nothing,
tonight i pulled the plate off the bottom of the
oil pump, no scoring in there, wasn't picking up junk, so damage had to be early on.
was some lifter issues before car hit the street, valve covers were filling up with oil, ...BAD.....found wrong roller lifters installed in motor, oiling holes in lifter lined up with the oil galley holes in the block and full oil pressure was running up the pushrods, pan might have gotten sucked dry who knows...
in the end comp cams replaced the lifters admitting to a mis-boxing of lifters for the 427, erroneously had 460 lifters in the box. builder missed this on install supposedly got dynoed like that so was the damage already done? don't know.
now on another oiling note, oiling up the pushrods with T&D's you also need to restrict the oil galley in the block between lifter banks, currently its got a .093 orifice, in looking at the way the rockers are manufactured there is an oiling hole to feed the roller, i believe i am still getting too much oil up top, there is a weep hole drilled in the adjuster to feed oil back to the roller. it also is .093 diameter. i think this is way too large, full oil pressure is shooting out of there all the time, totally unnecessary.
what i see is the oil is actually pooling above the valve seal and when the piston is on its down stroke is acting like a syringe and sucking oil onto the backside of my valve through the guide...
any feed back from other people that are using the T&D's and have played with the restrictor size to fix this please chime in.
i have my own idea to go maybe .050 in the galley and also restrict the cross hole in each adjuster to stop the flood
