Hi - New here - looking for some help please

Hey there, so you got me really curious and so I'll post a few videos for you to do some personal inspection on your end. I would also recommend putting in the Youtube search bar 'white smoke coming from toyota prius'

 

Yep all this has been hashed out here for years

 

Remove the spark plugs

pressurize the cooling system with a test kit & pump

put a video borescope into the plug holes and look for coolant trickling into the cylinders

The borescope can also reveal evidence of steam-cleaned piston crowns in affected cylinders.

There are 7 different ways a head gasket can fail.

A 3rd generation Prius does type #7 most often. You will not see any oil in coolant or coolant in oil with this type.

 

Well, to take a high-level view?

First you decide how much more transportation you want to get out of that car. Then you start figuring out what it might cost.

Then you have to evaluate the current head gasket failure- has it been knocking and bucking for a long time? It may not be worth putting a new head gasket in- there may already be deeper damage. If that's the case, you need to think about a used or rebuilt engine.

Then do the real math: What lines up best with your future expectations for the car? Is it worth a rebuilt engine installation? Is it worth all the labor of a new gasket? Or is it better to call it quits and move on to another car? It isn't a one-size-fits all.

 

How's the oil consumption, say miles per quart?
