    The throttle body and 90° pipe with PCV connectors were just caked with crap, the throttle blade was just completely black.
    After a full can of tb cleaner, the end result:

    Here's how the intake looks behind the TB:

    The PCV hose in the pic is full of crud and sludge and this car might have some sort of issue with the PCV. Eh, not today.

    Also the intake pipe has different diameter ends so I "fixed" it, since getting a silicon ricerpipe would require more fiddling.

    Tightening the hoseclamps, I dropped my ratchet into the engine bay and since it was dark, I'll continue tomorrow. I'll check codes too, my dad has a codereader.

      Pipe is now back in, ratchet retrieved from the depths of the ancient swedish machine.

      Fired up nice, so atleast I got the plug wires the right way. I had it idle for a while, no misfiring. Didn't sound like there was any intake leaks so my classy duct tape fix probably works, hopefully for some time too. The problem might be reoccuring, but atleast didn't happen this time.

        New year, new warning lights! Nvm, it's still 1,5h till 2020...

        Went out, for about 5 kilometers everything was normal, then the trans arrow light started blinking, trans went into limp mode and Malfunction Indicator Light came on (little lambda symbol, basically the check the engine light). Idle was also a little wavy.

        Drove back home, read the codes, a generic TPS faulty code, erased it and it didn't return.
        Everything seems to work normally again. Trans light went away, idles fine. Except the CEL light is still on, but there's no codes, I even checked again later.

        So my car got problems, I basically said no and erased code, now works fine? Except that damn light...
        Man, this car...

          random dead spot in the TPS might be the issue.

          if it doesn't give codes for un-metered air source, your tape fix works.

            From what I read, the CEL just might be "left" on, someone mentioned on the interwebs, so I removed the battery, we'll see if the light goes out.

            Also from reading: These 10v engines apparently don't have a MAF sensor, instead, a intake temp sensor in the same hole.

              speed density then? If so then it won't care about air leaks so long as the MAP has proper vac signal

                Reconnected the battery, fired right up, no more engine light. I guess all it needed was a reset.

                We'll see how far I drive tomorrow without a christmas tree of dash lights

                  Well I didn't get any warning lights on the dash...

                  I'm pretty sure the silicone gasket stuff failed between the intake and throttle body, idle at park is a solid 2000 rpm and in gear about 1400rpm.
                  I gotta redo all that crap, also I'm a bit afraid that I might have stripped some threads on one of the bolts that attach the TB to the intake.

                      I certainly hope so!
                      I'm still going back and forth about the carb swap idea. Then I'd be modifying and not repairing, which is a big difference.

                      The main annoyances in working on the Volvo is everything usual is somehow packed behind something that otherwise never needs to be removed etc. There's quite a bit of space in the engine bay, but it's not utilized at all.

                        As I suspected, the silicone wasn't sealing anymore. Confirmed by spraying start spray around the throttle body. It had failed from the "underside".

                        At the parts store only sheet gasket material available was way too thin, so I used the 1mm fire-resistant sheet that I used in the MGM's EGR.
                        Boltholes I punched out with a hole punch and carved out the holes larger with a carpet knife. The center hole I cut out with tinsnips, those worked incredibly well.

                        It isn't pretty and the holes aren't exactly round but hopefully it'll work. I don't see why it wouldn't.
                        I'll get put back together tomorrow, ran out of daylight today.

                        Half an hour fiddling saved me about 8€ and a week of waiting.

                          As long as there's good contact area on both mating surfaces... it should work well.

                            flat gaskets aren't magic. I've made plenty of carb gaskets in similar ways, usually using a hammer to tap out the pattern and whatever cutting tool made sense. Tin snips work really well for thicker material.

                              I was putting back the throttle body, casually tightening the four bolts in to the aluminium intake. Those bolts feel weird, it's like they start tightening but the resistance doesn't increase. Without much effort, one bolt just snapped.

                              I got the rest of it out with locking pliers, found a similar bolt, in with a washer. Even has a 10mm head like the original.

                              Got everything back together, seems to run fine, idle is back to normal. Hopefully the gasket lasts.

                                I recently finished up some tune up work on the benz I have. The upper part of the valve covers house a PCV breather valve cover that is held in with an assortment of hardware ranging from actual valve cover bolts (both sandwiching this upper piece and the lower together) as well as some aluminum bolts into the aluminum valve cover which were very thin. Despite being warned numerous times about NOT over tightening those thin bolts I snapped one. The bolt literally was just snug and then snapped. Working on cars can be fun....
