Peugeot Boxer excessive oil usage SOLVED!!

[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.

Hi guys, You may have just saved me a new engine!! Discalmer: I have a Boxer, 67 plate however its not a camper (Yet), just a Van carrying PA systems all over the country! Anyway, I have EXACTLY the same problem you have. It's been guzzling oil like nobody's business for a couple of years, No smoke, No Leaks and nobody could give a solution other than, 'cut your losses and get rid' or 'new engine time'. Any way, hopefully this will fix it. The DPF clean light has just come on and it's gone into limp mode. I recently did a run up to Scotland and it used around 2.5Ltrs over 600 miles. I think its pumped it all out the exhaust and clogged up the DPF. Its off to the shop tomorrow to get looked at. I'll furnish the mechanics with your info. Fingers crossed!!

Good Morning Alan
Pleased to hear you are all sorted.
We have a Peugot boxer 2.2hdi blue with oil burner issues.
Just put in 2 Litres of oil after 550 miles.
We've got no leak etc and no emissions issues.

It's a 2 ltr blue HDI.

Hi
I have all of these symptoms and was searching for a new engine before reading this. I have what I thought was oil in my coolant expansion tank but my mechanic said it’s soot. Is it possible that the PCV fault mentioned could cause soot to enter the coolant and soot up the expansion tank? Or does the fact that there’s soot in there mean it’s caused more damage to allow soot into the coolant. Thanks in advance for any help

The water and oil circulation systems are totally separate in an engine unless there is a problem like a blown head gasket or something else.

If it is soot, then it means you are getting combustion products mixing with the coolant water, possibly a head gasket issue ?

Or, if the engine has a egr cooler a leak in there ?

Are you also loosing oil?

Soot in coolant is normally EGR cooler, but you would also have dropping coolant, unlikely to drop your oil level though.

E&A, thanks for your post, it's good info, btw, what was the milage on the Boxer at the time?

Does anybody know if this is a regular service item? - I'm thinking not. Considering the trouble (and expense you've been through) this would be a good item to add to a service.

The mention of the old school diesel fitter; that's an increasing problem these days. The method of plugging in the reader and following the screen is all too common, if it's not on the screen they're lost - and so are we. I had an old boy with one tooth diagnose a failed water pump in a minute that a garage full of livery sporting technicians and screens couldn't in a whole day, charged me £790 for the privilege. (Books & covers comes mind)
