1NZ- FE engine oil consumption

just because it has good compression doesnt mean its perfect , you typically have 3 piston rings ...two for compression and one for oil control 

the oil control ring could be broken /damaged , and often the piston will have a oil return hole in the ring groove , were these cleaned before assembly ...im speaking in general as im not an expert on this engine  

do you see smoke from the exhaust?  is it wet inside the tailpipe?

smoke comes and goes . does not smoke continuos 

id either take it back to the repairer or find a good used engine

You can add a recording (video with sound) on here, that way all can hear what’s going on.

Do a video recording with sound and use the Add Files, or Other Media. I have Added Files successively but never used Other Media.

Check to see if its getting sucked up through pressure valve into inlet, you might be burning it all off.

If you take off the air filter and look inside, should give you an idea, whats going on.

Kuda, Did you solve the problem with your 1NZFE engine? Toyota 1NZ-FE Engine | Reliability, tuning, supercharger (mywikimotors.com) that article may help. above 150 000m, problems may occur on that engine. I dont know if yours had passed that mileage.

Quote, "http://mywikimotors.com/toyota-1nz#: Apart from the above-mentioned things the oil pressure switch is frequently disarranged and the rear crankshaft oil seal leaks time after time. The cylinder block can’t be repaired. So after running 150 000 miles (200 000 km) you will probably have to purchase a new 1NZFE engine."

Take note of the highlighted. Aluminium was used in its construction maybe thats why it can't be repaired... I guess..

Cheers..

Those articles are so generic and poorly written I cannot take any of it seriously. Using aluminium in an engine is hardly unique, nor troublesome.
