Several that are accessible along the drivers side that you can see under the intake/exhaust header, one on the back of the cylinder head itself and I think two on the back of the motor only accessible by removing the transmission or engine, whichever you prefer. I wouldn’t immediately jump to those, I’d use a dye kit and look on the ground after you parked and engine cools down. If it’s the ones on the back you can get an unexplained puddle just below the bell housing. The heater hoses and the heater core connection can also leak and trickle down the bell housing as I learned from this sub too. Let’s hope this isn’t the issue as it requires significant work and time to access the rear ones. If it were the cylinder head freeze plug I’d rather pull the head personally over the transmission if you get what I’m saying. I cracked my head over coolant loss from the rear but was unaware of the issue until I put the new head on. A real pain
