Comline is proud to unveil its new range of timing chain kits, engineered to deliver OE-matching quality, robust reliability and backed by an impressive four-year/100,000km warranty. This launch marks a significant development in Comline’s engine parts portfolio.

Timing chains were once considered a lifetime solution. Today, many independent workshops report that this reputation no longer consistently holds true. Across a growing number of modern engines, technicians are seeing timing chain failures at lower-than-expected mileages – in some reported cases, as early as 30,000 miles. These failures can result in high-value, labour-intensive repairs, often requiring engine or gearbox removal, with extended labour times and an increased risk of costly comebacks.

On certain modern engines – including widely discussed applications, such as JLR Ingenium, VAG TSI and BMW N47 – timing chain work is becoming a more regular feature in the workshop.

A familiar problem for workshops

Modern engine designs can place increased stress on timing systems. Higher operating temperatures, extended service intervals and compact packaging may all contribute to accelerated wear, while early warning signs can be easy to overlook.

Workshops commonly report:

• Cold start rattles that worsen over time
• Chain stretch, causing timing issues before fault codes appear
• Partial repairs increasing the likelihood of repeat failures

Once a chain issue escalates, the consequences can be significant, not just for the vehicle, but for workshop efficiency, customer confidence and reputation.

Comline’s response: A new generation of timing chain kits

These real‑world trends have driven Comline’s launch of its new timing chain kits. Developed by Comline’s engine parts team, drawing on more than 40 years of specialist experience, the kits are manufactured in OE factories and tested to meet the demands of modern engines.

The range launches with over 300 SKUs, covering many commonly serviced applications, including JLR Ingenium, VAG 1.4 TSI and BMW N47.

Workshops can choose between basic kits – containing the timing chain, guides, tensioner and pre‑lube – or full kits, supplying all components required for a complete timing system replacement.

Key features include:

• OXICOAT® chain pin coating for improved wear resistance
• 360° full‑load chain pin staking for consistent strength and durability
• Laser‑marked tensioner torque settings, helping technicians install components accurately and efficiently

All Comline timing chain kits are backed by a four‑year/100,000 km warranty.

Designed to reduce risk and improve efficiency

For workshops, timing chain repairs are among the highest‑risk jobs on the ramp. Comline’s timing chain kits are designed to help reduce that risk by supporting complete, first‑time‑right repairs.

The benefits include:

• Helping reduce comeback risk by enabling a full system replacement rather than partial repairs
• Supporting confidence on commonly reported problem applications
• Faster, more straightforward installation, thanks to technician‑friendly features that reduce guesswork on complex jobs

Real‑world validation through The Car Edition

To reinforce confidence in its new timing chain kits, Comline has partnered with respected, UK-based workshop and YouTube channel sensation The Car Edition, using real repairs to demonstrate real results.
