Ideas on what's causing my click/tick/rattle noise?

One more thing @halfafish, well, 2 more. The Slanty mechanical pump is upside-down, & can leak fuel into the crankcase w/o coming out of the weep-hole, I know this for a FACT. The 2nd point, be very attentive & sure of the ring instructions, position-type-orientation-face up. Some rings appear similar to the old ones, but are installed "counter-intuitively", be certain. It seems a simple task,but I've seen um in wrong, & by pros. Be sure to avoid causing heavy scratches or gouging the ring lands.
