Our evidence‑based process restores factory performance, fixes legacy design issues, and aims to have you back on the road within two to five working days—subject to parts availability.
*Warranty applies to the engine long‑block (head, block & sump) when serviced in accordance with the Ford schedule. See full T&Cs. †Turnaround measured from strip‑down approval; exact timing depends on parts supply and machining queue.
*For the complete checklist please read our Terms of Service.
Streamlined machining, real‑time parts tracking, and parallel QC stages mean most EcoBoost units are completed within one work‑week.*
Our team rebuilds hundreds of three‑cylinder EcoBoost engines every year, following Ford's published tolerances and our own tighter internal limits.
Upgrades and revised parts address wet‑belt wear, coolant‑intrusion porosity, and turbo oil‑feed restrictions before they cause repeat failure.
12 months / 12,000 miles* comprehensive cover
Below are the four failures we encounter most often, along with the engineering steps we take to prevent their return.
Over time the belt's rubber absorbs oil, sheds fibres, and can block the oil pick‑up, causing a sudden drop in pressure—typically between 60 k and 80 k miles.
Early heads suffer from casting porosity that allows coolant into one or more cylinders, leading to misfire (P0300‑P0304) and potential hydrolock.
Sludge in the oil feed restricts flow to the turbo's centre housing, accelerating bearing wear and causing blue smoke and loss of boost.
Direct injection means the back of the intake valves never see fuel, allowing hard carbon deposits that cause cold‑start misfires and reduced MPG.
