Either a head gasket, cylinder bottom seal(s), or warped block/heads.
Usually water flows into oil (under constant pressure). Milky white
foam in the crankcase is traditional indicator. Check for it on
dipstick. Look for steam in exhaust from warm engine. Can also
pressure test coolant system.

If you opt to remove heads yourself note PRV has special technique.
Don't simply lift straight off block -- can disturb cylinders/bottom
seals. You slide head (can't remember if towards engine center or away
from it. Martin?) then move up & off in an arc. Or so my Volvo
literature explains.

Both Rich A and Travis G have done own head work within past year for
first hand info.
