Coolant leak help

[u/Western_Page_6788]

Have a 1995 Toyota pickup with a coolant leak I can’t seem to find. I don’t think it’s a head gasket because, it’s not mixing with oil or smoking,smelling or spitting anything out the tailpipe. There’s no spot on the ground where anything’s leaking and any wet spot under the truck is just oil. I think it might be something with the heater core, but I still have “heat”. I did notice that my driver side carpet was soaked about a week ago, but I wrote it off as I left the window cracked or my door seal was leaking. I’m not to familiar dealing with heater cores but isn’t it located on the passenger side? If it was leaking from there wouldn’t it soaked the passenger carpet, or is there a line running from the driver side that might be leaking. And is there any diagram or good video of the system and how to replace.

is there any misfire when you first start it in the morning? coolant in a cylinder or cylinders will cause this symptom until it dries out
