Could it be turbo again ? 2008 xs

If that’s the crankcase breather, the only time I have seen anything like that is with very worn rings or a cracked piston, how many miles on the engine? Regards

Lovely i6 has now gone, but not me......

Please let me know if anything in my post offends you, as I may wish to offend you again......

Also possibly very worn valve stem seals........ Regards

On my previous cars, I always associated this with a blocked oil breather pipe or filter, and found that a good dismantle, clean and poke worked.

However on one car (1964 Vauxhall HA Viva) it turned out to be a sticking piston ring, although that was accompanied by lots of exhaust smoke every time I re-applied the throttle after over-run.

Extract from manual
Excessive engine blow-by/crankcase pressure

Engine breather system blocked/restricted
Excessive engine wear

Check engine breather system for blockage/restriction.

FL2 Metropolis SD4 Auto 2014 2017- (16k - 76k+ miles) (MY2015)

There is a Pressure Control Valve in the Crankcase Ventilation System.

Maybe worth checking?

Crankcase Ventilation System
To prevent the build-up of gases in the engine's crankcase, the crankcase gases are drawn into the oil separator where oil particles are removed from the gases. The oil is then drained down to the engine's oil pan and the gases are directed into the engine's air intake system. Prior to the oil-free gases entering the air intake system, a positive crankcase ventilation (PCV) valve operates to minimize crankcase pressure variations caused by engine air demand and engine operating conditions. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

Thanks for the advice
The top hose, is the engine breather
My thinking is,as it’s got good/even compression

I removed the turbo to intercooler pipe.
It had about a litre or more of oil in it

Hello
My fl2 is running great now
It was the turbo, I’ve rebuilt it using British made parts this time

At idle the turbo produces zero boost. But the pictures suggest the turbo was still letting exhaust pressure straight through to the oil return line into the crankcase.
