- 204ps Bi-Turbo CXEB T6 Engine & Turbo problems -

How long will the engine last when it starts using more than one litre of oil per 1,000 miles?

Will it slowly get worse until it consumes oil faster than diesel?
 
The engine will keep going for as long as there’s oil in it but everything else will clog up, egr will clog up and dpf will clog up resulting in blown turbos etc

Good question!

I’ve been on 0.5L per 1000km for about 50,000 miles.

I’ve had to replace turbo and DPF in that time.
 
I had the same, it was coming up to 40k miles for me when it was getting closer to a litre on 600 miles and we decided enough is enough
 
With approx 2 bar boost pressure there’s a good chance the PCV isn’t managing to separate all of the oil vapour out and it’s going through the induction.
I’ve mentioned it elsewhere on the Forum, If I had a T6 or any other turbocharged vehicle that was consuming oil I’d fit an inline oil separator.
It maybe a temporary measure just to eliminate the PCV passing oil vapour.

Yea this is advice I’ve read from you and I need to investigate. Is this something I could ask a garage to do?

I do basic engine stuff. Oil changes, filters, etc, but not sure I could do this.

It’s a case of buying a suitable separator pot, locating it in the engine compartment and connecting one side to the existing PCV connection and the other side to the existing induction connection.
 
New member here who has just sold a rock solid, ever reliable, T25 Westfalia with a 1Z 1.9TDI engine fitted that we drove around the UK and Europe on many occasions doing 1500-2500 miles per trip and it never used more than 0.5l of oil per year...now looking at a 2017 Caravelle or Kombi...the Kombi I know has the CXEB engine and I'm reading this forum with dread about whether it is worth the risk of buying or not - appreciating this post is the doom and gloom one, does anyone have a rough idea of % of failures?

I have a 26year old 996 and that has similar forums of woe about IMS and RMS bearing tanking the engine if they fail, but reality suggests it only affects 1-2%, certainly less than 10% of all made....so before I make a decision to buy or walk away, I'd be really grateful for any insight.
Thanks in advance

I’m not sure anybody can give you the statistics but oil change intervals, DPF back pressure and mapping have been linked to failures in some cases.
Don’t buy it if you can’t afford to fix it would be my advice.

Thanks for the quick reply. Budget for regular maintenance and prevention (EGR delete?) is fine, but I've definitely not got an extra £10K for a 'this might go wrong' fund....so just getting a sense check whether this is a 75%+ chance of happening or is it 50/50 or are the odds better ?

The best you can do is to carry out an surprise Miller oil analysis providing the oil has enough mileage on it and you have the correct data to supply with the same.
Review the oil service history, 20K extended oil service interval is a signal to run away as is missed service. Ideally these engines would have oil changes at 7-8K miles IMO purely down to soot content.
Plug in and check the DPF health.
EDIT; any evidence of an engine map or boy racer toys I’d do a runner.

No sign or report of map or boy racer toys.
Any idea how long the miller oil analysis takes to return?
"Plug in and check the DPF health." assuming via ODB2 scanner?

Is it a safer bet to look for a 150bhp model or post-2019 Bi-T?

If it were me that’s the one I’d go for. A well looked after 204 might still have been driven solely on the school run for example and short journeys kill diesels over time. So while service history, lack of maps/huge alloys - whatever, may indicate the van is fine you’ll never know how it’s been driven.

My other concern though would be resale - there will be people put off by 204s or might consider buying but want a low price to enable saving to be held for an engine replacement.

Also, I don’t find the 102 miserable/dangerously slow. It’s fine for a camper. I’d welcome a little more power, and especially a 6th gear, but I don’t need double the power. A 150 would be fine in my mind.
