BMW Repair Questions? Ask a Mechanic for Answers ASAP
Not at all I would like the question answered satisfactorily as it will be useful to gauge your experts' knowledge and my outlook working with you guys in the future.
Thank you and best regards
The first thing I'd check is the crankcase pressure relief valve (PCV) these are sprung loaded and are only meant to 'burp' excess pressure every now and then. The exiting gas is piped back to the inlet , however should the valve stick open then the engine tends to suck the air out of the crankcase all the time and this carrys oil over with it.
If you remove the air intake pipe and look inside where the crankcase breather is plumbed in you may find evidence of oil.
If you do find oil replace the valve.
Also check inside the intake just after the turbo for any signs of oil as this would be an indication that the turbo oil seal is starting to fail and a replacement / rebuilt turbo may well be required. Have a feel of the turbine wheel - there should be no play radially at all - but a little bit of axial / end to end float is normal
I have 2 supplementary,related questions:
1) I had run a computer diagnostic which showed as follows: obd2 diagnostics show error code P0192: fuel rail pressure sensor low input.
Do you know if the sensor would contribute to the problem I asked about in any way? Damm thing is sooo expensive for being such as small bugger.
2) I also noticed that while accelerating the power required for the booster to start operating was not being generated & therefore the accelerating very poor.
Does this related to the probability of the turbo oil seal that might be faulty/radial play on the turbine wheel?
Thank you for an early reply as I intend to buy the parts asap. Brgds, P.
I live in northern Panama, Boquete and mechanics here are few and far in between and no one know how to work on a BMW X5.
I have been looking for a replacement cranckcase pressure valve for my E53 3.0d 2006 (I can only check the condition of the current one on this coming thursday) and I have seen on the net that it would be better if I bought a crancase pressure valve of a E70 3.0d because they have a vortex filter which is far superior. Do you agree or can advice me in the purchasing of this valve? Thank you for your kind attention
