This is for the twin scroll engines, which the ST never got. Disregard.

 

Ok. Thank you. Also, twin scroll? I'm not familiar with those engine types. Every time I hear twin scroll I think supercharger.

 

Single scroll and twinscroll refer to one or two volutes in the exhaust housing of the turbo. Twin scroll funnel opposite cylinders into each of the scrolls.

You're thinking twin-screw, for the supercharger example.

 

The 2017 and up 2.0 EB escape motors are twin scroll. I've got 81k on mine and thus far it's still good to go (knock on wood).

 

Ohhhhhhhh. Got ya. OK. And I may have been.

 

Now, definitely top the coolant of your car off and check it every couple days to make sure it isn't actually leaking! We do have a few common leak points.

 

Which are? I check every oil change and the last one I did a couple weeks ago I haven't seen and leaks. That's why I was concerned about the leaking into the cylinders from not enough cylinder wall gap between cylinders due to an open deck cooling system they switched to in 2017. The 2020s changed it to a cross drilled cooling system between cylinders to give more cylinders wall surface for better head gasket seal.

 

ST engine is closed deck:

Open deck block; never came in the ST:

 

First determine if the level's actually dropping.

Again. You have the closed deck single scroll Ecoboost. Our cars never got the changeover.

 

The bean counters are accountants not engineers. That’s what happens when you lets an MBA design your engine.

 

The facts.
