My friend has a 2012 3.5l ecoboost F-150. I imagine all these are twin turbo but if not, his is.

I don't know anything about these blocks and would like to know the cross compatibility between engine blocks. His truck has about 140k miles, and recently got a hole in the block. He though maybe he lost a turbo line or something, but after we brought it to my house and I got a closer look, we saw a hole in the block near the motor mount. (It shoots oil from the hole and quite a lot of it) Somehow, it threw a rod or something catastrophic. He had it for about 50-60k miles at did normal maintenance so this must have just been a anomaly for these engines, or maybe they aren't as good as I've heard, because it seemed to be very well maintained.

Anyways, he needs a new block, but everything else seems to be in working order. Do the explorer/flex motors work in the F-150s? Or will he need a specific ecoboost that came from an F-150? It would be nice to just get a block and re-use all the other components of the motor so he won't have to spend so much on another engine.

Thanks for any help/advice. It really sucks his motor is damaged when he still has a lot of payments......

 

This is from Wiki. It does identify transverse mounted engines differently from truck engines. I'm not sure if that changes the characteristics of the block.


The production engines use the Duratec 35 V6 engine block. The fuel charging and delivery systems can attain high fuel pressures up to 2150 psi, necessary for efficient operation of the direct fuel injection system. The F-series EcoBoost 3.5L V6 uses two BorgWarner K03 turbochargers which can spin up to 170,000 rpm and provide up to 15 psi of boost. The transverse EcoBoost 3.5L V6 uses two Garrett GT1549L turbochargers and provides up to 11 psi of boost. The turbos are set up in a twin-turbo configuration. The engine can consume up to 25% more air over the naturally aspirated counterpart. Through the use of direct injection, the engine needs only regular-grade gasoline to run. The EcoBoost V6 was first available as an engine option for 2010 Lincoln MKS, followed by 2010 Ford Flex, 2010 Ford Taurus SHO, and 2010 Lincoln MKT.[57] The fuel-charging and -delivery systems were co-developed with Robert Bosch GmbH.[58]

 

Thanks for the response. They may be different then.. I suppose we'll try and do a little more research. It will be a few months before he decides if he's going to get another motor or not, so we have some time to get this figured out.

 

Full dressed drop in engines are about 3k. Not that much money. The car engines used a different block casting. Car-part.com

 

That's not too bad. It's pretty bad for a semi-new truck with only 120k miles though, but really shouldn't be too bad!

I was seeing them for about 4k on ebay, but if we could get one with the same or less miles for around 3k, I don't think it would be too bad really. I haven't messed with these motors, but I would imagine pulling it wouldn't be too hard. I've pulled 305s, 302s, and 7.3s, so this should be relatively easy I'd imagine.
