Also, I took the thermostat out. It is blowing white smoke and oil is cream color. But never ran hot and has been driven one mile after thermostat was removed no all this.

Hello,

That color of oil typically indicates a blow head gasket which allows coolant to mix with oil. That also creates white smoke out of the tailpipe.

Keep in mind that to have a leaking head gasket the engine does not have to overheat. It can leak due to wear and tear.

Here is a helpful guide on how to check for blown head gasket:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
