Help with coolant leak toyota pickup


Hello everyone, I need some advice to solve a coolant leak I have been chasing for a couple of weeks. This is a yota pickup 1991 v6 DLX, 3.0, 4x4 manual trans. I started to see coolant around injectors on driver's side, just where the connector are, this leak goes down passing behind timing belt cover, passing down thermostat. Reading through the posts I found that this can be caused by the upper timing pulley, so I replaced it, the gasket looked bad and apparently there was the leak coming from. I drive it for a while and the leak is still there. I noticed that this only happens when I leave the car for a day o two turned off.

This is the place where I see the leak starts.

I would enter some UV dye into the cooling system and then do a pressure
check to no exactly where leak is coming from.
