Welcome to TacomaWorld
White smoke ?
Are you loosing coolant ?

 

When you have an old motor like this that runs well with RPM, as you say... Like maybe this is an older truck that has been sitting. I find a good technique is to take it out of the barn, change the oil. Then take a long drive at fairly high speed, with the motor humming along for an hour or so.

That is going to blast all the crud out. Then change the oil again, while it is still hot.
