What is a “wet belt”?
The Ford 2.0 EcoBlue diesel (fitted to most Transit and Transit Custom vans from around 2016 onwards) uses a timing belt that runs inside the engine, bathed in oil — hence “wet belt.” It was designed to be quieter and more efficient than a chain, but as it ages the belt sheds tiny particles of rubber into the oil.
Why it kills the engine
Those shed particles get drawn into the oil pump pickup and block it. Once the oil pump can't pull oil through, oil pressure collapses — and a diesel engine with no oil pressure destroys itself within seconds. That's why the failure is so sudden and so catastrophic, and why a dealer who hasn't opened the engine will quote you for a whole new one.
Symptoms of wet belt failure
- Sudden loss of power while driving, sometimes with a bang or knocking
- Engine cuts out and won't restart
- Oil pressure / engine warning light before it died
- Rattling or whining from the engine in the weeks before
- Excessive oil consumption or oil that looks gritty
If your van has done these and now won't run, don't keep cranking it — that can make the damage worse. Get it recovered and assessed.
What does the repair cost?
Main dealers routinely quote £4,000–£5,000 because they price for a full engine replacement without inspecting what's actually failed. In reality, many wet-belt failures are repairable for far less. We do this one job all day, so we offer a flat £2,800 +VAT for the wet-belt failure repair — engine damage assessed on inspection, with the price confirmed before any work starts.
