Update: used a shrader valve and a pvc end cap to create a diy boost leak tester. Used a bike pump and found a signifivant leak in the tps side of the throttle body. Are there any bolts I could tighten here? Gaskets I could replace? O rings/seals I could replace?

Is it the throttle shaft bushing that is leaking? maybe there's a seal hiding in there behind the tps.

There's an oring sealing the TPS to the throttle body, don't recall if that side also has a shaft seal. The other side has a seal. Pro tip, the part number for those seals is the same as the part number for valve hushers, per VIDA. The aftermarket hushers need just a tiny trim, otherwise they are too thick.

Ok managed to seal the throttle body tps side using a generic o ring. Now I found a new leak. Bubbles are now coming from the black idle adjustment thumb screw on the throttle body. How can I seal that? Teflon tape or something?

Edit: have done a little research and some people mention loosening a lock nut before being able to adjust they’re base idle. Don’t know if this applies to my throttle body but if it does I don’t believe I have a lock nut, just the thumb screw threaded in.

The thumb screw doesn't have a lock nut. The lock nut you're seeking is on the throttle lever adjustment screw. Time for more research.

Seems to me like he’s talking about the thumb screw adjustment here :

Can the throttle lever adjustment screw adjust idle speed? Because earlier in the article he already discusses how to set that screw, then he refers to the screw above as if it’s something the reader has not read about yet. I most certainly could be wrong but that’s just how I saw it.

Aside from that, does anybody know how I could seal those threads up? I was thinking (even if there isn’t a lock nut stock) I could thread a nut and an o ring under neath the nut on to the thumb screw before screwing it back in. Once the screw is set correctly, tighten down the nut with the o ring underneath hopefully sealing the threads.

Definitely time to read up on how it works. There's a throttle stop screw that yes, it can adjust the idle speed. Then on LH2.2 cars there's a thumbscrew as well to fine tune the adjustment, 2.4 cars don't have this.

Ohh I understand now. But the real question now is how do I seal it?

Maybe teflon pipe thread sealant, allowing the sealant to dry before reinstalling.

According to the parts diagram the o-ring fits on the adjuster. Apparently the thumb wheel just screws out of the housing, lube the o-ring, slip it onto the adjuster and reinstall. Volvo part number for o-ring is 947114.

11.0 (7/16") OD
6.7 mm ID
2.4 mm thickness

Closest I figure on standard o-ring size is:
7/16" OD
1/4" ID
3/32" thickness

Found a slightly bigger o ring for sale in my city with the dimensions of :

3mm thick with a 6.5mm ID. Groove is 3.2mm wide so it should fit. It should also be slightly bigger and hopefully seal it up better.
