I think I still have the original 150,000 mi Bosch one...would it be worth trying to clean it?

It passed!!! No fucking idea how or why though. I repeated the emissions test and it failed exactly the same way. Then I went to one of those emissions shops (A van actually) and we put a monitor on it. It was throwing the P0102 code again, so I jiggled around the MAF sensor in case the wiring was l...

It couldn't be that hard to do the PCV on an N/A car. You're options are read up and DIY, or bring it to a shop and bend over. Bend over is right...I called the shop I've taken it to before and they wanted $850 to service the PCV....they wouldn't even do the CAT because Volvo doesn't make them any ...

Come on guys, give him the magic answer. You guys know that no one wants to do the proper maintenance. Why else would he have paid top dollar ($4000) for the car. In the time that has been spent chasing this post, the system could have been replaced. It literally can be done in 2 hours on a NA car....

PCV is a pretty long job, you are probably on the mark in your assessment there. I can't think of any shortcut to dealing with the flame trap, you have to take apart a few things (accordion intake hose and airbox both come off pretty easily, that should make enough room to get in there and open up ...

I'd say you'll need a catalytic converter too. Not sure what the laws are in Seattle, it's $80 for a mangaflow cat and then labor to install here in AZ. :D how in the hell do you get a CAT for $80?!? the stock one is like a grand! Platinum is fucking expensive, I can't see how they can do that. But...

With emissions reading that high, it could be a slew of things going on. I agree with everyone else though, PCV system (while not easy task) is likely one of the main culprits here. No easy fix/silver bullet for fine-tuning and emissions. It seems weird to me that the cruising emissions would be fi...

I believe (need to double check) that both O2 sensors were replaced about 60,000 miles ago.

Ok. I did the glove test and it failed (ie. the rubber banded glove inflated on the oil cap). I hard reset/drive cycled the computer. The car hasn't thrown a P0172 code since replacing the vacuum line, but is throwing a P0102 code, which it had previously thrown but I had thought was due to my disco...

jblackburn has a good DIY for it, which also includes lots of good information on the system. https://www.matthewsvolvosite.com/forums/viewtopic.php?t=28487 Wow that is an awesome post, thanks! But also looks like a huge job...How hard would it be just to pull the flame trap housing http://www.trac...
