I have gone out of town and will back at it this weekend. Problem not solved yet.

Check the idle valve on the side of the power steering pump. When they go bad fluid starts to get dumped on the intake. This could also cause white smoke.

I will check that out this weekend also, thanks!

I replaced the engine coolant temp sensor and still kept getting the coolant sensor code. I traced the wiring back to the ECU and all good, continuity and no shorts. I then figured the ECU misinterpreting the fault pointed to it. Found 3 leaking capacitors. Hopefully the damage to the board isn't enough to be an issue. Will order a kit and get past this point. Thanks for everyones input.

As I have told you. Hope the traces were not badly damaged.

Ok, finally got the new capacitors soldered into the ECU. All code are gone, idles steady, still puffing a little smoke but I think it is residual gas in the pipes. Finished pretty late so will back it out tomorrow and see how it runs.

I have no smoke until idle gets to around 800rpm, after that I have smoke. Still appears to be white in my eyes. No signs of oil contamination. I still haven't done a leak down test but that will be next.

My bet is your pulling power steering fluid in due to the power steering valve. If you have no signs of a head gasket leak then the power steering fluid is the next culprit.

Ok. I plugged the vacuum lines to see what happens. Same result. But, I told the owner to go drive it. I believe it boiled down to the ECU, re-learning the engine conditions after replacing the capacitors. I'd like to thank everyone for your input on this problem. A good education for me and a happy neighbour lady able to drive her baby again.
