Thread: Puma 2.2 burning oil!

I mentioned oil because I read Toyota had to change the recommendation on their TDV8 because they were burning oil. But, if the right oil was used in this case, then it's not that.

Sounds like excessive blow-by. Whack a catch can on it, and monitor.

Idel the engine and open the engine oil cap....Video it and post it here Please

I am curious and would like to compare yours to mine....

Got a tricky problem with my 2016 defender that i thought collective wisdom may be able to assist.
Cars done 111,000 and it's started burning heaps of oil over the last 5000kms. I'm talking more than a litre every 1000km. No loss of power, no obvious smoke on start up or high revs, no starting issues, no overrunning on shutdow, no oil leaks. Oil pressure checked and all good. Rocker cover and sump off and nothing obviously out of place.
Heaps of oil through the air intake and turbo/intercooler. Appears to be coming in from the hose that runs from the rocker cover to the air intake just before the turbo. I'm thinking its pumping too much oil up to the top of the motor, and essentially overflowing but seems strange. Maybe the oil pressure relief valve in the oil pump?
If anyones got any ideas would be much appreciated.
Cheers

More than likely leaking injector washers which puts compression into the engine causing crank case pressure which fills intake with oil pretty common with a lot of late model diesels because the injector is sealed internally in the engine so any compression past the sealing washer creates crank case pressure.seen engines rebuilt for this problem from people not nowing
hope this helps

Either I'm daft and in need of education, or something does not seem right. How does leaky injector seal cause excessive oil usage?

In the 2.2, the injectors have a copper seal at the tip of the injector. If this fails, then cylinder pressure on the compression stroke would leak past, and to atmosphere. As far as I can tell, the 2.2 injectors are sealed only at this point. If they did leak into the head itself, then even going as far as into the intake air galleries (unlikely as far as I can tell from the service manual), then they'd still be fighting boost pressure, and still only be dumping fuel and air...
If the injector is leaking, then yeah, surely there'd be symptoms of difficult to start or excessive fuel usage.

IMO, if there is oil usage, and present at the PCV hose, then it's coming from the crank case. And this happens from blow by. I can't understand the mechanics of what you've suggested, but I'm keen to know more.

You need to be more specific

Run the engine up the temperature,

Open the oil filling cap
And pinch the Pvc hose. That the one OP was talking from engine catch can to right before air Box. So that all blow by is coming from the cap

Smell it

Mine smells pretty carcinogenic. Had I Decat my car, it would have smell like that all day every day (sorry can't resist haha)


One thing I can contribute is that I installed a catch can so I can measure blow by. When dealer serviced my car, they used some Castro a2 (I think) and that oil is not for a truck equipped with DPF.
When I did the service, I use Castro OE-X that is the engine oil for diesel truck with DPF. I know the 2.2 didn't have DPF But for whatever reason Castro inform me I need OE-X)

And I discovered using the engine oil desgined for truck with DPF in my case will lead to more blowby. But not anywhere near what OP described as burning close to 1 Lt of oil per 100 kms....thats some expensice oil consumption...

Castrol....
