Went to pass a car on highway and suddenly lost power and oil pressure, coasted to the side of road and switched off the engine and waited for a tow. Coolant and oil everywhere on under side of engine. Anyone know what could have happened? 2011 v6 ecoboost 3.5 liter, 174k miles. I'm no mechanic so any help would be greatly appreciated. I'm thinking a turbo went out but the fluid is on both sides of the undercarriage from turbos down and back toward transmission and oil pan.

 

More than likely toasted them. Sounds like the bearings seized.

I bet if you took the intake pipes off the turbos and stuck your finger in there and tried rotating it, you'll likely see and feel either a frozen turbo or it's wobbly. Hence causing no boost, hence having no power.

Very expensive to fix.

 

What's the chances they both blew at exactly the same time?

 

Well, the root cause is lack of cooling. These turbos are cooled by coolant -- not oil.

So if you sprung a coolant leak, and those turbos ran dry, they are done. It can happen to oil cooled turbos too. Actually, happens all the time.

 

This is hard to diagnose without actually looking at it. A competent mechanic should be able to diagnose it properly. If you blew both coolant and oil, it may be more than just a turbo.

 

Not the turbos, found a hole in the block today

 

That will do it!

 

Sure will.

Surprised it didn't make a loud bang or pop.
