Peugeot Boxer excessive oil usage SOLVED!! (1 Viewer)

[Evoller]

Thank you all who suffered alongside us throughout last year with our Boxer conversion dilemma.
Our 2017 Boxer started going through an excessive amount of oil - 2Ltrs in 300 miles. No smoke, no drips - no idea!
We had two turbos, new oil pump, oil solenoid, oil switch, new ECR, all suggested as 'possible remedies' by a major 'Diesel Specialist'.
When all of this failed to fix the problem, they announced our engine was shot and advised us to accept that this has been the case all along and we'd just have to accept it (including £2000 in bills). Turns out it was a stuck PCV valve!
If any of you suffer these symptoms, find a good old fashioned Diesel fitter who knows his stuff and save yourself a fortune!!
Thanks all for your patience and input.
Happy camping in 2024 !!

It's a 2 ltr blue HDI.
The issue looks to have been long running. The PCV was likely stuck open (old 100k miles). The PCV dumps into the main air hose to the turbo compressor. So the high air flow in the main hose was sucking on the rocker box (Venturi) via the stuck open PCV. Oil vapour was being circulated to the intake manifold where the oil was being combusted and sooting up the DPF to a state of fully blocked, there by putting excessive exhaust resistance to the turbo. So the whole issue could have been fixed with a £200 replacement PCV and rocker cover assembly. A quick check you can do is pull off the hose (sprung hose clip) and stick your finger into the hose and then into the PCV an see if you have excessive wet oil on your finger.
