V70 D3 'fails' the glove test + smoke from filler

[graphnic]

Whenever I buy a new car I like to get a feel for the common issues, which in 2022 inevitably means the rabbit hole of Youtube. I came across a few folks testing their PCV with the 'glove test'. Inflation indicating a possible PCV issue. Most of these videos don't refer to the diesel engines however.

Out of intrigue, I gave it ago, and inevitably, it inflates.

I have also noticed some smoke when removing the oil filler cap. I guess with the lack of vacuum, this correlates. Here is a video of both the glove and the smoke. https://www.youtube.com/watch?v=Ge4q33sQVn4. It sounds terrible in the video but sounds and drives OK on the road, as far as I am concerned. It does seem to knock a bit with the filler cap off though.

Is there an issue I need to investigate further here?

I scanned for codes using the 'Car Scanner' app, and there was an 'inactive' code for 'P003A(85) Turbocharger/Supercharger boost pressure control A - learning limit exceeded'. This is recent, and I haven't seen it before.

It's a D3 136BHP MY2014 with 93k miles. Recently purchased and have just done the cambelt etc, a transmission oil flush, the rear trailing arm bushes and service. The indie Volvo specialist felt it was all in good order, and with all that work they had spent a bit of time with the car, including a test drive.

Your hive-wisdom welcome. Thank you.

My D3 makes that exact noise when I take the oil filler off and smokes also.

Not done the glove test.

Sure I read previously about that test on the diesel engines and that it was normal for them to blow up.... Could be wrong.

Good to know. It does sound a bit like a traction engine with the filler off😂

Hoping you’re right regarding the vacuum. As a person with limited knowledge, I was intrigued by the method and now feel compelled to follow up the result!

Does your also have positive pressure and did you conclude it was normal?

The pressure there is so low it is almost zero. I'm no expert on this, but with such a low pressure I would not be concerned.
