2008 LC200 2UZ - lots of white smoke on cold start

[SMRM]

I've also seen really bad vacuum leaks in the block (hardened front crank seal) resulting in the PCV system working overtime sucking oil-saturated fumes into the intake, resulting in lots of smoke upon startup every now and then. Eventually the vacuum (and oil!) leak got so bad the engine didn't run very well and was throwing some codes for out-of-range mixture trim, etc. New crank seal and problem solved. This was on a different engine, but something else to check.

Gonna book it into a mechanic who specializes in the 2UZ / Toyota engines here and find the cause of this. Will keep yall updated

Hi,
