what do you think about this.. i just got my block back from the machine shop after it was bored, decked , checked and all oil passages cleaned. brought it home removed the plugs from the mail oil gallery and ... a whole bunch of dirt, grime, rust and you name it. yeah i know it was flushed but it looks like you got to remove those plugs and check every time. It's good now but i had to manually clean it and reinstall the plugs.. from the oil gallery its a straight shot to the bearings.
