Is it the head gasket? Where do I start? 2015 LR4 SCV6 with 92K Miles. …. Thanks for any and all help and suggestions.

 

white smoke is typically water vapour…
How is the coolant level?
Gaskets, cracked heads…

 

Do you have any codes? Is it misfiring? Sometimes the fuel injectors stick open dumping fuel which can't be burned. This causes white smoke too and is a lot easier than a coolant entering the cylinder issue, so I'll keep my fingers crossed for you.

 

make sure your PCV valve and vacuum pumps are not the culprits before you jump off a bridge.
