How We Saved a Customer’s Engine

At MB MOTORS Rugeley, we specialise in protecting our customers from costly engine damage. One of the most dangerous and often overlooked issues we frequently resolve is wet belt failure. This detailed case study highlights how we diagnosed and repaired a degraded wet belt system just in time, saving our customer thousands of pounds.

What Is a Wet Belt and Why Does It Matter?

A wet belt, or belt-in-oil system, is used in many modern engines to reduce friction and improve efficiency. Unlike traditional timing belts, a wet belt runs inside the engine oil. However, over time, these belts degrade and cause significant issues such as oil contamination, sludge buildup, and oil starvation.

This issue is common in vehicles from Ford, Peugeot, Citroën, and Vauxhall, sometimes occurring as early as 40,000 to 60,000 miles.

Case Study Vehicle – Ford Focus 1.0 EcoBoost (2018)

A customer brought in their 2018 Ford Focus 1.0 EcoBoost for a routine service. During inspection, our technicians identified several red flags indicating potential wet belt degradation:

  • Visible sludge around the oil filler cap
  • Metallic noise during cold start
  • Low oil pressure on diagnostic scan

We recommended a detailed strip-down to investigate the condition of the wet belt system.

Diagnosis – Confirmed Wet Belt Failure

Upon inspection, we discovered the following:

  • The belt was delaminating
  • Rubber particles present in the oil pickup
  • Clogging beginning in the oil pump

Had the customer delayed, this would have resulted in complete engine oil starvation and likely crankshaft or turbo failure.

The Solution – Full Wet Belt Kit Replacement

We carried out a complete wet belt replacement using OEM parts. This included:

  • New wet belt
  • Oil pump drive belt
  • Sprockets and tensioners
  • Full oil flush with engine flush treatment
  • OEM-grade oil filter
  • Fresh engine oil to Ford specification

Every step of the job was documented for the customer, including photos and video updates from our workshop floor.

The Result – Engine Saved and Costs Avoided

The engine was preserved, and the customer avoided potential £3,000+ repairs. The vehicle was returned fully serviced and protected, with a 2-year or 20,000-mile warranty on parts and labour.

When Should You Replace Your Wet Belt?

For vehicles with belt-in-oil timing systems, we recommend:

  • Replacement no later than 6 years or 60,000 miles
  • More frequent inspections if the vehicle does mostly short journeys
  • Using correct oil specification and regular oil servicing

Ignoring these guidelines risks severe damage to the engine, turbo, and oil delivery systems.
