I've had a small coolant leak going on, now it seems to be getting worse. I've noticed that when I use the heater it seems to leak faster, and I wouldn't have heat. I'm thinking it's the line in or out of the heater core, but I'm not sure because I can't see anything. I am seeing coolant pool and drip from the oil filter housing which I have a picture of. Any ideas or diagrams that would help?

I didn't see the picture did you upload it? We should pressure test the system and then get under the tuck with a flashlight, and then look around on top of the engine and hoses.

here are two guides to help:
