Engine oil top up in between service

[clemgoh]

Check your crankshaft seal. Look from the top down below the crankshaft to see if there is oil stains.

Yes. Good point also.
This is working down the list of oil leak issues. Crankseals are next but usually should be like 100,000km mark I think.

For most bimmers - the EO consumption stays the same from cycle to cycle.

I would check the crankcase pressure next ...

Crankcase pressure?

If pressure leak oil will burn?

If no visible oil leaks around the engine bay area (usually black clumpy oil with dust), the seals or leaking on floor after overnight parking, then its usually internal leaks.

1 way to find out whether it is internal leaking (and burning internally) is to start the car after overnight parking, idle for about 10min, rev the accelerator hard at P or N and observe the exhaust.
If lots of WHITE fumes, then confirm internal leaks.

Happened to me and the usual culprit is worn VALVE SEALS. cheap spare parts but a little bit on the labour. I bought the seals from ES and went to one of the site sponsor to change them as warranty already over. No problem after that.

Since it will involve opening up of the engine, I took the opportunity to change ALL the valve cover gaskets, and oil pan.

Hope it helps

Thanks! V comprehensive....

Anyway I will be checking in to PML on 23/8 to have my car checked...

Cheers
