Engine completely disassembled, cleaned, painted and stressed parts magna fluxed, and reassembled with the new high quality performance parts:
- Schrick cams-288 intake/280exhaust high lift and duration
cams with dual vanos retained
- Schrick DLC coated finger followers (rockers)
- Upgraded to JE pistons – 12.5-1 compression versus stock
- Schrick DLC coated rod and crank bearings with ARP bolts
- Dual vanos rebuilt with new gear, seals and O-rings
- All engine slide guides, tensioner and twin timing chain
- Head completely rebuilt, 3 angle valve grind, new guides and
seals, new valve springs
- ARP head studs were installed versus the stock single use
head bolts.
- All new sensors (cam, crank, throttle position sensor, oil
pressure and Turner in -pan oil temp sensor
- Bimmerworld oil filter housing upgrade to increase flow to
100% to oil cooler
- Oil pump upgrade to eliminate pump failure
- New coil packs

Engine has some kms put on it since build (over 5k km). The rate of oil burned is not a fixed rate. Around the city with a few rips here and there i need 0.5L every 1000-1200 kms, sometimes more sometimes less - it's really just based on how frequent and hard the rips are. That brings me to my next point. Aggressive runs (canyons, track) consume/burn far more oil. I did very remote backroads yesterday to get some data and basically at what would be 70% track-level intensity for an experienced driver (frequently/often in the power band), I had put 2L over about 250-300km of aggressive driving; 600km total including slow zones such as neighbourhoods and highway mileage as well.

That number, however, is less than half of what it was before and a few things changed since then.
1. Tune is no longer running crazy rich
2. Evolve airbox may have been pulling oil out of the ccv, plugged and catch can installed. Catch can has a bit of oil in it - but not much, probably under 100ml.

So the engine builder has said that because the tune was really rich it was affecting the cylinder walls, etc etc which I do understand but I still don't think it's supposed to result in this much oil being burned. Interestingly though the catch can and oil cap both smell like fuel, so there may be some merit here.

I will do an oil change now that the tune has been sorted out to see if it makes a difference or not. I just don't think I've ever come across an issue like oil burning being tune related (as a result of running rich).

I took it to another shop for a second opinion, but that guy didn't even know the difference between static and dynamic compression so I didn't have enough confidence in him to actually let him take a look.

Lastly, if rings were were an issue would engine still be making power on the dyno?
