    Was driving and noticed the CEL started flashing. It only flashes when I go over 30mph and then goes back to solid when I go below 10mph. Anyway, everything sounds fine, no knocking or ticking, but when I got home I crawled under it and found a mess.

    Please have a look at the pictures and maybe point me somewhere to start. Looks like it is mostly between the oil pan and the transmission case.

    I would have said oil cooler lines/oil filter adapter till I saw the last pic of the starter. Pretty sure the the oil pressure sender is at the back of the block, behind the distributor. I would start it cold, when the oil pressure is higher, and look around. Maybe get someone to rev the engine to 2,000 for a little more pressure/flow.
