Intermittent loss of power

[RickHaleParker]

It has a banjo bolt. (the one that connects the thicker pipe to the right side of the engine)

Right side of intake manifold.

Am I correct in assuming the fact that the dipstick gets pushed out releases the pressure?

Yes failed glove test is proof of excessive crankcase pressure.

If so, I don't really understand how it can be building up further, since the dipstick is always out now (I deliberately never push it back in).

If the PCV system is in good working condition and you are still getting excessive crankcase pressure at idle. It indicates higher then normal blow-by (Gases getting past the piston rings) . Can you get a Borescope and look at the pistons and cylinder walls?

I suppose I could get a Borescope, they don't seem to be that expensive ($100 - $150) and seem like a handy thing to have, although I'm not sure what I would be looking for in the cylinders.

If that is the cause, wouldn't driving faster just cause it to build up even more pressure? (this does not happen, at higher rpm the car runs fine).

You can get USB Borescopes on eBay for less then $15.00. Then use it with a PC or a Smart phone. Make sure the Borescope is at least 2 Megapixels with LED lights. 1920 X 1080 is 2.07 MP.

You are looking for Stuck rings. Strunken pistons. Carbon buildup.

Compression test numbers could be useful.

[protonsnow]

Are the compression numbers something that will show up on Volvo Vida (+ DiCE)?

Did you remove the Oil pan doing the PCV service? You can unclog the passage from the PCV into the engine, but it runs a bit deeper than that and is probably clogged up near the oil pickup

Lidl is your friend for those, usually have em for 50€

Thanks. You could be right. I did not drop the oil pan. It's a bit too much for me right now. I don't have a proper place to do these things and have been doing them in the street in front of my house (which also means, whatever I start, I have to finish the same day, and once all my tools are out on the floor with all the parts, I can't even leave them for a pee. It's a pain in the butt). And last time I jacked up the car on the street and got under it I was harassed by the cops. And since everyone is overly sensitive right now because of covid nonsense, I'd rather not risk it. Before you know it they'll try to force me to wear a freakin' mask while working on the car.

Maybe I'll get a quote from Volvo for that (infamously expensive in this country. They once quoted me almost 500 Euros just to change the oxygen sensor, which I ended up doing in 20 minutes for under 60).

[Poppafranku]

You live in the same country as I friendo, I know that pain, hah.

I also do all of my work, though luckily I have a place to do things where the car can stay for about a day, even if it is my daily.
Do keep in mind that taking off the oil pan isn't THAT bad of a job on these cars, in my experience anyways

[protonsnow]

I was searching for a video on how to remove. Only found one with an s60, and they removed front tyre, timing belt, engine mount...

I'd rather not mess with the timing belt right now.

Things were so much easier when I had a 1979 mini.

Yea right get one at the Supermarket. They are right next to the Potatoes.
