Sup fellas?

Sorry for the question but my account won't let me search for some reason. So here it goes, my friend has a '95 with an automatic, it overheated last night on stop and stalled as it came off the light.... I put in about half a gallon of new coolant/water (50/50) and the temps went back down, drove fine.
The next day, we went to look for leaks and I saw some coolant oozing slowly around the oil pan gasket, but probably not exactly from the gasket. I don't know exactly where the leak is because there isn't much room to look at past the crevices. The hoses felt fine and the radiator showed no leaks.
It gets weirder, as I asked them to rev the engine as I observe the leaks, the engine was revving itself like three times while my friends blipped the throttle. Then, the thing won't go past 15 mph without bucking like crazy... Does this mean the end of the Max? Sorry for the long post. Thank you for your time.

 

Remove Oil filler cap, run your finger inside to see if the oil is foamy, if it is normal then at least you haven't blown a head gasket. The "oozing" is concerning

 

Sounds bad. Although rare to hear about a blown gasket on a maxima... Im sure someone will have more knowledge on this.. so *bump*
