My 98 S-10 4.3 has oil cooler lines that I've replaced 3 times in 200K mi. because they sprung leaks from the crimped joints or the O rings where they bolt to the engine above the oil filter. Also check the front seal. You'll need to wash the engine off to find all of your leaks if oil is everywhere now. Looking at where the oil falls when it's parked can get you close to finding what is leaking and you've probly got more than one leak if it's over 150k.
 
Another vote for cooler lines. Just had one come through, rod knock, replace motor, new cooler lines. Old ones had pressure bubbles where the interior wall was compromised and spring several leaks to the world. Rear main seal. Valve covers. Oil pressure sender. I've seen the senders leaks quite profusely, out the electrical connection at that.
