At Turbo Care NZ, we're seeing an increasing number of Garrett GTD1444VZ turbocharger failures on Ford Transit 2.0L EcoBlue diesel engines caused by restricted oil supply, rather than a fault with the turbocharger itself.
The Problem
The oil feed line contains a fine mesh gauze filter designed to protect the turbocharger from contaminants. Over time, this filter can become blocked, and the plastic support inside the feed line can also deform or collapse, restricting oil flow.
Even a small reduction in lubrication can quickly lead to overheating, bearing damage and premature turbocharger failure.
Common Symptoms
- Loss of power
- Turbo noise or whining
- Blue or black exhaust smoke
- Excessive shaft play
- Burnt or coked oil inside the turbo
- Premature turbocharger failure
Before Replacing the Turbo
Before installing a replacement turbocharger, we recommend:
- Inspect the oil feed banjo bolt and integrated gauze filter.
- Replace the oil feed line if contamination or restriction is found.
- Inspect and clean the oil return line.
- Change the engine oil and filter using the manufacturer's recommended oil specification.
- Verify engine oil pressure before fitting a replacement turbocharger.
- Prime the replacement turbocharger with clean engine oil before initial start-up.
