I think the last pic is the rollover valve, not an Intake air control valve. That’s seals up the Evap system in case you roll the car over like June does every once In a while. If the hoses on it are fat, like 1 cm thick, that’s Evap. A leak there, or a split can make a hissing noise , too.

Non turbo cars in 99 have an iac. Turbo cars in 99 do not, it’s built into the electronic throttle body system ( ETB, ETM, or ETS are all used to describe that)

Have you found the name of this plastic part. I broke mine and need to replace it. Can't find a part name or number anywhere.

https://usparts.volvocars.com/a/Volvo_2 ... 28023.html, here's you r rollover valve.
Is there any part number on the plastic adapter block? There is an o-ring on the FPR, is thee a groove for one on the mounting location for the plastic adapter?
Current Volvos:
1998 V70 T5, 112k sat 5 years, still in mechanical coma (finally at the top of the pile )
2004 XC90 T6 AWD: 186k, 60 on transaxle ( traded in )
1998 POS70 N/A: DD/training aid, 236k but really about 240k, I think...ABS module( passed on to son who sold it)
