3. Engine Overheating A failing tensioner can affect the water pump's performance, potentially leading to overheating and serious engine damage.
An overview of the different standard types of oil seals and their main characteristics is shown below.

Common Oil Seal Failure Causes
6, the seal is cheap.

There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.

Polyurethane
In motor vehicles, spark plugs play a critical role in igniting the air-fuel mixture within the engine cylinders. High-quality iridium spark plugs are designed to provide reliable ignition, efficient combustion, and consistent performance, contributing to the overall efficiency and longevity of the vehicle. The use of iridium spark plugs in motor vehicles can lead to improved throttle response, smoother acceleration, and reduced emissions, enhancing the driving experience and environmental impact.
Materials for Oil Seals
The perfect solution to this is to always use an oil seal that fits properly; the right size of the seal should be used. And in other cases, backup devices should be used to avoid the buildup of clearance gaps within the mating edges.

Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.
Select your oil seal type according to Table 2.
O-rings are the most commonly used seals as they provide incredible value – very affordable, versatile, and efficient. They are made with several elastomer materials as to the application they will be used for, so it’s important that you know the materials an o-ring is made of before purchase.
