Help, my 911 SC 78 Started Smoking and leaking

[MKEDF]

Hi There!! hope some one can help me..

I just bought a 911 SC 78, as i was driving towards San Diego, it started smoking, and leaking oil....

No light was on regarding to oil pressure loss, but still a leak, and considerable amount of smoke even black oil at the muffler...

I checked under the hood and it looks fine, but on the right side where the oil filter is, it was like sprayed with oil...

Do i have to change only rings? or is there any other really hard concern to have....may be reduild??... Thank you all, please heeeellp....
