Engine, gearbox and belt faults: repair or sell?

Work out which repair is being proposed

A description such as blown engine or failed gearbox can cover very different damage. Ask what has actually failed and how the garage reached its diagnosis. Engine work might involve a repair to the existing unit or fitting a replacement. A gearbox fault might concern internal gears, bearings or its controls. Clutch wear can cause slipping and difficulty transmitting power without the gearbox itself needing replacement. If a belt has failed, the garage needs to establish what happened inside the engine before you can compare repair options properly. Avoid buying an engine from a listing based only on the van's badge. Engine codes, specification and the work needed to fit it matter. Ask the garage to confirm compatibility and the complete job before committing to a replacement. A Ford Transit engine for sale is a part listing; it does not tell you the cost or scope of getting your Transit back to work.

Engine, gearbox, clutch or belt?

• Engine trouble may involve knocking, overheating, loss of oil pressure or failure to turn. Stop safely if a serious warning appears and get mechanical advice before another starting attempt.
• Gearbox symptoms can include difficulty selecting gears, unusual noises or loss of drive. Tell the garage which gears are affected and whether the symptom changes as the van warms up.
• A slipping clutch can let engine speed rise without the expected increase in road speed. Mention any change in pedal feel or difficulty moving off so the diagnosis covers the clutch system.
• A timing-belt failure may stop the engine suddenly. Keep it switched off if failure is suspected; repeatedly using the starter cannot establish the extent of any internal damage.

Wet belts and the 2.0 EcoBlue

A wet belt is a timing belt that runs in engine oil. The 2.0 EcoBlue wet-belt models covered here are the Ford Transit Custom, Transit, Ranger and Tourneo Custom, plus the VW Transporter T7 and second-generation Amarok NF. The T7 shares the Transit Custom's engine, while the Amarok NF shares the Ranger's. This does not mean every engine fitted to every version of those model names has a wet belt. Confirm the engine in your own van before relying on belt advice. Belt debris can obstruct the oil pump pickup and reduce oil supply, causing bottom-end engine damage. A snapped timing belt can also cause internal damage because valve timing is lost. Vandervan buys these vans after a belt has snapped and after bottom-end failure caused by wet-belt debris obstructing the oil pump pickup. You can describe that damage in an enquiry without paying to make the engine run first.

Questions for the garage

A belt-change interval depends on the actual engine and its maintenance requirements. Use the vehicle's correct service information and discuss its history with the garage. This guide gives no universal mileage or age for replacement. If the engine has already failed, the immediate question is the extent of the damage and the work needed to address its cause.

Compare repairing with selling

Repair can make sense when the diagnosis is clear and the van will still meet your needs afterwards. Compare the complete estimate with a realistic repaired value and a valuation in its current state. Include any diagnosis or dismantling already authorised, and ask the garage about charges or release arrangements before booking collection. Selling allows you to move on from an unresolved or extensive repair, but it still needs an accurate description of the van. Tell vandervan which unit has failed, whether the van starts or moves and where it is parked. Share the garage's report if you have it. We collect free from home, work or a garage and pay on collection day before loading. A van with engine or gearbox failure can be sold without first ordering replacement parts.
