This orifice goes to your block right? What the block entrance also plugged up or did the goo only appear in that location after you took the box off, moved it, and let it sit for a bit? I'm asking because from that picture, it woud look like your block entrance where the breather box drains was als...

When I got my s70 a few years ago at about 110K, the PCV failed the glove test. When I took mine off, it looked like the below picture (not my car). Not as bad as the below picture in terms of % clogged. However the below picture does give a good representation of the type of debris I found waiting ...

You should always get ~6 quarts between the pan and filter when you drain the oil. If there are leaks or you’re burning some, obviously that’ll be slightly less. I think you’re talking about the small coolant pipe/nipple that allows oil buildup to drain out of the intake manifold. Below is the XC90 ...

Coolant flows through that pipe & they used a banjo on that end because of the close quarters. You don’t want to forget copper crush washers for either banjo. If you forget the coolant banjo crush washers you’ll have a coolant leak. If you forget the crush washers on the intake manifold bolt you...

Intake manifold looks great, and that same stuff can clean the cat(s) too.

They are blank no name coils. I will try and swap them around. And plugs I used bosch platinum. The ones with 4 prongs around the tips... With as many misfire codes as you’re getting I wouldn’t be surprised if you don’t have ANY known good coils to swap around. But before dumping a bunch of money o...

Plain old single electrode/copper Volvo/Bosch plugs are time tested & proven, especially on turbo models. That being said, it’s most likely that your coils are the problem vs your 4-electrode plugs. Get know good coils in there and then proceed along to trouble shooting.

Oil will go dark pretty quickly , don’t worry about that. The oil filter will catch the particles that matter, the fine stuff that looks black is too small to matter. If the owner went long on oil intervals you will be rinsing sludge out for a few oil Changes.

If those have been in awhile they need heat to be applied for thee -four cycles ( propane, 60 seconds, then 10 minutes cooling) to break the bond. If you have a stub of stud left you can apply heat to that and use a sharp vice grip to turn it out. If not, the heatshirld can be zip tied back in A sma...
