The 2.0 EcoBoost's open-deck block can crack and let coolant into the cylinders — a documented failure Ford addresses with a short block. We diagnose it honestly and do the complete repair at your home.
The 2.0 EcoBoost uses an open-deck aluminum block — the cylinder walls stand free at the top rather than being tied into the deck. It saves weight and helps cooling, but under years of boost and heat cycling, the deck area can crack or the head gasket can let go between a coolant passage and a cylinder. Either way, coolant gets pulled into the combustion chamber. Ford has a TSB on the condition, and the factory fix isn't a gasket — it's a replacement short block, because a cracked deck can't be reliably sealed.
The symptoms are textbook coolant intrusion: the reservoir drops with no puddle anywhere, white sweet-smelling smoke on cold start as the coolant that seeped in overnight burns off, and misfires on the affected cylinder — usually P0301 or P0302. A combustion-gas test on the cooling system or a borescope look at the cylinder (steam-cleaned pistons are the giveaway) confirms it.
Diagnosis matters enormously here, because the repair path splits: a true head gasket failure on an intact deck is one job; a cracked block is a short block replacement. We pressure-test, gas-test and borescope before recommending anything — you should never pay for a short block on a guess, and never pay for a head gasket that's doomed to fail again on a cracked deck.
If your Ford is doing any of these, this is the likely cause:
Coolant in a cylinder washes the oil film off the cylinder wall, hydro-locks the engine in extreme cases, and steam-cleans the piston while contaminating the oil. Every week of driving on intrusion grinds the bore and bearings. Caught early, the rest of the engine is salvageable. Driven for months, a repairable engine becomes a dead one.
Yes — with honesty about what it involves. We bring engine support and lifting equipment, and the vehicle stays in your driveway or garage for the duration instead of sitting in a shop queue. For a multi-day job we secure everything between sessions. It's a big repair; it's still better at your home than at the back of someone's lot.
Because Ford's prescribed fix is a new short block — a major parts cost plus days of book labour at dealer rates. Sometimes that really is the right repair; sometimes a properly diagnosed head gasket job on an intact deck is. We diagnose first, then give you one flat quote for the complete correct repair before any work starts.
Testing, not guessing: a cooling system pressure test, a chemical combustion-gas test, and a borescope inspection of the suspect cylinders. A cracked open-deck block can't be fixed with a gasket, so confirming which failure you have is the most important step of the whole job — and it's where we start.
Usually worth fixing if the rest of the vehicle is healthy — these are otherwise solid vehicles, and a repaired or replaced short block resets the engine's life. We'll give you a straight assessment of the whole vehicle along with the quote, and if the math doesn't favour the repair, we'll tell you that too.
