Hey guys my name is Matt. I drive a 1998 Honda Civic dx hatchback, it has the stock 1.6 d16y7 motor in it. Last summer it was leaking antifreeze and I came to find out my head was warped so I had the head gasket replaced, head machined and valve work done, and I had the timing belt and water pump replaced as well. It was running pretty good until about two weeks ago, my car overheated. I checked the radiator and overflow and both were empty. I have no idea where it is leaking at, I don't see any leaks at all. I had my friend (who owns his own shop) pressure test my coolant system and didn't find any leaks. He also checked the head of the motor and said its still fine, compression is Good.
A few days ago I felt like my car was running a little cooler than normal and I wasn't getting any heat in my car, until I drove it a mile up the road then hot air came out. A bad thermostat can't be the culprit to antifreeze loss though right?
It kinda looks like it's been leaking under the distributor somewhat , it's hard to tell though.
Car is running good , runs at normal temperature. Doesn't smoke, there isn't coolant in my oil , etc.. Any ideas as to what could be the culprit of my antifreeze loss? Thank you guys

Pressure test the cooling system, look for obvious leaks.

Then head gasket checks, like checking for leakage from the combustion chambers into the cooling system.
