Volvo S80 2.4T PCV DIY Repair / Service

Repaired / cleaned the PCV circuit as I saw a lot of oil in the pressure circuit (also see my previous post: http://www.ducked.nl/blog-entries/volvo-s80-2-4t-dirty-clean-turbo-coldside/ ).

Did a little research and the PCV system is almost always the culprit for such issues.

Decided to buy a complete system although ended up cleaning the existing system and only replacing the oil seperator. The tubing was quite some work, I will save that for another time.

Volvo S80 2.4T Changing the Interior Combo filter

Needed to change the interior / combofilter and was suprised by this malformed unit.

Looks like someone didnt do their job properly…Shameful really.

Easy DIY job, which shouldn’t take more than half an hour.

Volvo S80 2.4T Fitting a new Compressor Bypass Valve (CBV)

I noticed some strange behaviour when lifting the throttle and decided to service the CBV aka Compressor Bypass Valve. I was right, car drives a lot better after replacing it with a fresh CBV / DV (Diverter Valve).

I went with an aftermarket TRITDT K5T09671.
