burning some oil. it could be a number of things. you will need to do a leakdown and compression test to find out what though. Rings are a good culprit, since its leaking into the combustion chamber. but you could also be leaking from the valve seals/guides. If you check out my spark plug thread in the NB section, you will see what a spark plug looks like when its been burning oil. take yours out and compare. If its only on one side of the spark plug, then its valve guides/seals. If its everywhere, then its piston rings.
Still need to do compression and leakdown though. Thats a good idea either way. Do you check your oil weekly? how much do you go through?
OHH!! You're FI'd also. So if your spark plugs look fine, it could be from the turbo seals.

Right now my front and rear crank seals are leaking. Like my new undertray is covered in oil. I was check my oil every other time I drove. Then I put some seafoam in my crank case and only drove it a little then changed my oil and filter. I haven't lost any oil so far.
FI? no I'm N/A.
I'll check out your spark plug thread and do a compression check.
thank you!

We replaced the rear main seal.
The oil leak was about the same. Then I put sea foam into the crank case then changed the oil after a few miles. Now the oil leak is extremely slow.
I am also going to change my VC gasket and then do a leak down test.
