Know the warning signs – how to tell when your turbo is failing
Oil problems, debris, overspeeding, wear and tear…there are a number of different things that can cause a turbocharger to fail, but catching a problem early can save you a lot of time, money and hassle in the long run.
At AET, we’ve been helping customers with their turbochargers since 1974, and in this post, we explore some of the tell tale signs that your turbo might be on the way out, or in need of urgent repairs/maintenance by one of our turbocharging experts.

This example shows a worn piston ring seal groove – in the image, you can see that the outer edge of the piston ring seal groove is sloping outwards, when it should be straight.
Turbos and temperature – summer weather and turbocharger performance
One common question that we often get from customers is why turbochargers perform differently depending on the time of year, temperature and weather. Generally, these customers have noticed a significant drop in performance on hot summer days when compared to cooler spring and autumn nights.
Whilst this is a common trait amongst all turbocharged vehicles, and isn’t anything to worry too much about – in this post, we take a look at why turbochargers produce less power in hot weather, and what you can do about it.
