Frequently Asked Questions

Is engine replacement worth it?
Only if the rest of the car is solid. A £3,000 engine in a car worth £4,000 rarely makes financial sense unless the car has sentimental value or is a sought-after model.
What causes engine replacement?
Most commonly: neglected timing belt/chain failure, overheating damage (head, pistons, bore), oil starvation from neglected maintenance.
