Is it time to replace your engine mounts?

Here are four signs to look out for…

Engine mounts may not be the most headline-worthy part of the engine, but they perform a vital role, protecting the components (and any operators/drivers) from shocks and vibration. Fibets’ engine mounts are designed to deliver consistent and robust anti-vibration performance year after year, but over time even the best engine mounts will start to show their age. Knowing what to look for in a deteriorating engine mount can help you address issues fast, before they have time to cause wider and more significant problems. Here’s what to look out for…

1. Increased noise and vibration

When an engine mount is worn or damaged its anti-vibration properties reduce. The first sign of that is often a growing awareness of unfamiliar knocking noises, or simply more engine noise than you’re used to. Vibration isn’t an easy thing to pin down. You’re unlikely to be able to see the cause (unless a mount has degraded to such an extent that it’s obvious – see below) and because vibration travels, the source of the noise is unlikely to be easily identified. But don’t ignore an increase in noise or vibration. The longer you leave it, the greater the risk the vibrations will become stronger and potentially damage other parts of the engine.

2. Jarring gears

If changing gears at speed feels clunkier and more jolting than usual, the cause could be a worn or damaged engine mount affecting the transmission.

3. The lurch

Significant damage to an engine mount can cause the engine to feel as though it’s ‘lurching’ when you turn the ignition on or off. The feel and sound of the lurch are both easily noticeable. Whilst things may quickly settle down, you’re likely to still notice an underlying and ongoing vibration whilst the engine is in operation.

4. Visual wear

Engine mount wear is usually not immediately apparent on visual inspection, but significant wear or damage can be. Look for cracks, corrosion or crumbling rubber. As engine mounts need to retain their structural integrity to do their job, any signs that the mount is degrading are likely to coincide with reduced performance. Replace any engine mounts that appear to be damaged as soon as possible.

When replacing engine mounts, it is prudent to replace the full set – because if one engine mount has degraded, the chances are that the others will have too.

By replacing a full set of mounts, it will avoid any additional expense and time involved in having to dis-assemble the adjoining components multiple times.
