1.5 EcoBoost ST (200 PS) introduced in the Ford Puma ST featuring a timing chain for the camshafts but retaining a wet belt for the oil pump drive.
Present - Continuous production with minor software refinements. Crucially the manual transmission variant avoids the oil pump belt tensioner found in automatic Puma models, slightly reducing one potential failure point.

Common Failure
Burnt exhaust valve on cylinder 1 (documented at low mileage, e.g., 30,000 miles, leading to sudden loss of compression) and standard wet belt oil pump degradation over time, though the manual ST avoids the automatic transmission's problematic oil pump belt tensioner.
The Ford Puma ST 1.5 EcoBoost delivers exceptional performance, but its high-output, three-cylinder architecture is susceptible to specific thermal and lubrication stresses. Rebuilt engines through EnginesMarket include upgraded components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.

Typical Failure Mileage
20,000-40,000 miles
Root Cause
High thermal load and specific combustion dynamics in the three-cylinder layout can lead to premature exhaust valve degradation on cylinder 1, resulting in a sudden loss of compression and requiring a complete engine replacement.

Our Recommendation
Our Recommendation
Given the high value of the Puma ST and the catastrophic nature of a burnt valve or oil starvation, a professionally rebuilt engine with upgraded valve train components and a new oil pump belt is the most reliable long-term solution. Do not attempt to run the vehicle if an oil pressure warning or sudden misfire occurs.

Ford Puma ST 1.5 EcoBoost Engine ReplacementFrequently Asked Questions
Question 1How much does a Ford Puma ST 1.5 EcoBoost engine replacement cost-
A full rebuilt or reconditioned Ford Puma ST 1.5 EcoBoost engine typically costs between £2,200 and £3,500, including supply and fit.
- Rebuilt units include upgraded performance components and a 12-month warranty.
- Main dealers often charge £6,000-£8,000+ for the same replacement.
- Used engines are a budget alternative, starting from around £1,200.
Question 2Does the Ford Puma ST 1.5 EcoBoost have the wet belt problem-
The Ford Puma ST 1.5 EcoBoost uses a hybrid setup: a timing chain for the camshafts, but a wet belt for the oil pump.
- Unlike automatic Puma models, the manual ST does not have the problematic oil pump belt tensioner.
- However, the wet belt itself can still degrade over time and shed debris, making preventative replacement at 60,000 miles highly recommended.
Question 3Is it worth replacing the engine in a Ford Puma ST 1.5 EcoBoost-
Yes, absolutely. The Ford Puma ST retains strong market values, typically ranging from £18,000 to £28,000.
- A full rebuilt engine replacement (£2,800-£3,800) represents a small fraction of the vehicle's total worth.
- Investing in a warrantied, reconditioned unit preserves the car's performance and resale value far better than a cheap, unverified used engine.
Question 4What are the signs of a burnt valve in a Ford Puma ST 1.5 EcoBoost-
A burnt exhaust valve on cylinder 1 is a documented low-mileage failure in this engine family.
- Sudden, severe loss of power or a persistent misfire.
- Illumination of the check engine light (often with compression or misfire codes).
- A noticeable lack of compression on cylinder 1 during a mechanic's test.
Question 5How long does a Ford Puma ST 1.5 EcoBoost engine replacement take-
A standard Ford Puma ST 1.5 EcoBoost engine swap typically takes 5 to 7 working days.
- This includes sourcing the correct 200 PS performance unit.
- Nationwide delivery to your chosen specialist.
- Physical installation, ECU calibration, fluid top-up, and comprehensive road testing.
