I have a 2007 d40 navara yd25 turbo and when running their are bubbles emerging out of the radiator, we watch it run for 40 mins to see wether it would clear and it didn't so it's coming from somewhere. The thing that confuses me is we did a compression test for 24 hours and it held compression meaning thereticaly their is no leak through the head or another part of the cooling system. We did check the EGR cooler as well and that's fine no cracks so where is the air coming from

This engine does sometimes have a head gasket leak just above the alternator. Get the engine warm an see if there is any water around that patch.
