The vehicle is a 2003 montero sport with the 6g72 3.0l petrol engine. I have a strange issue where there is white/ greyish smoke from the tailpipe after I pull away hard from an idle about 5 minutes.
There is no smoke when driving, acceleration, or in cold starts. Coolant level is steady but there is a slight drop in oil level.. I have top up oil like 200ml-500ml every 5000km but this was a common thing before I started noticing the smoke. The tuneup is also good as I see water droplets from the tailpipe and mist when i hold a glass or the phone screen on to the tailpipe. The engine runs smooth and silent.
I did an exhaust smoke test and the readings were as follows if that indicates any issue,
|RPM 870 (idle)|RPM 2350
--------------+--------------+---------
HC ppm v/v |322 |65
--------------+--------------+---------
CO % v/v |0.55 |0.22

Lambda |1.08 |1.10

O2 % v/v |2.25 |2.16

I read online it maybe valve seal/ guides but my mechanic says it cant be as the engine runs very smooth and has a steady power delivery.
Is there anything else that may cause such a behavior or can it be the valve seal/ guides?
Thanks alot
