Lexus IS 220 (177km) Engine Issues: White & Blue Smoke, Oil Consumption, Turbine & Lambda Probe

hello I have a problem with the lexus is 220 177km engine when it warms up at higher revs it smokes blue and white and gently draws oil. the turbine after the replacement, I put on the lambda probe, I had a similar case in the crafter where the mechanics replaced a new turbine, the engine overhauled, the total amount of repairs was 10 thousand and the cost of the probe was PLN 300 and my hand was gone. maybe someone knows more about these lexus 2.2 engines and will help.

They repaired the engine because it probably took coolant. Did they replace the entire post or the gasket itself?
What does the exhaust differential sensor show?
I had the same thing in my car. Sometimes it left gray smoke behind. It turned out that the DPF had melted and burned out very often.
These cars are a bit primitive when it comes to error handling. My exhaust gas difference sensor showed at idle from -100mbar to 300mbar and yet the controller did not detect a fault. Hence the damage to the DPF
