1998 impreza bubbles in overflow
Hi, so I have bubbles coming into my overflow tank, however there is no sign of bubbling in my header tank. I can feel the bubbles coming from the turbo return pipe that leads into the header tank and also feels like the they are coming from the direction of the turbo not the header tank.
Could this mean I have a crack in the hot side of the turbo which goes across the coolant passage

Coolant still gets pulled back through and levels don't drop. No other signs of a headgasket failure. Spark plugs have just been out and changed, no smell or signs of coolant in the heads. Car starts fine and quick so no signs low compression but going to do a compression check anyway. Hasn't over heated. I've tried the car without a thermostat to see if it was that obviously temp stays low, only time it rises is when I go into boost. Other sign that makes me think turbo is the turbo return line kept splitting
