They showed me a tiny set of holes around the perimeter of the ring, of a car already disassembled when I got there. These holes get clogged up and send lub oil upwards in to combustion chamber instead of back to engine sump over liner surface. As more and more oil is pushed on to combustion chamber oil burns.

You can get what you want done from most (not all, to be fair) government servants but only if you know how. Once a guy was even bold enough to give me a rate table .
