    Sounds like bad valve. Run compression test with VCADs Pro

    Ore if u have no Volvo Diagnostics, turn ignition off, jump starter and post video here like it sounds when starter cranks engine w/o fire.

    IMO, bad exaust valve ore exaust manyfold leak.

    May be compressor head, but IMO sounds like exaust valve
