Damsel in distress

You all are wonderful. Molly's girlie parts (engine) is a 170ci- 2.8 slant 6. Oil was all over the passenger lowerside wall and on ground. No where else. Drain plug good, no holes in block or pan... I think that answers all of your questions ;)

And btw a big thank you for all of the diy stuff in here. I could barley are up my tires and a guy made me mad at a auto shop because I'm a woman so I researched and learned how to do all of the repairs thus far on here. I'm pretty sure it's the head gasket based on what I've read so I'll probably just have the whole engine done if that's the case since it will all have to be taken apart for a $26 part lol. But I want to make sure since I'm a woman and obviously incapable (not) of knowing cars
