Engine mounts for tuned engines

A tuned engine needs strong engine mounts

Also called engine mounts, they provide sufficient rigidity while cushioning the engine's vibrations. As a result, they increase ride comfort as well as cornering stability. You can find more advantages of engine mounts, their function and installation here.

Function: What are engine mounts and what are they for?

Engine mounts, also known as engine mounts or engine mounts, connect your engine to the body and cushion the engine's vibrations while maintaining optimal stiffness. Because tuned engines bring corresponding power and vibration, mounts also play a big role in professional tuning. With the right engine and transmission mounts, cornering stability is increased, engine tipping is reduced, there is no jerking during load changes, and gears are easier to engage. They also reduce noise transmission, so above all they make driving more comfortable and fun.

How are engine mounts constructed and what material are they made of?

Engine mounts consist of the following elements:

  • Engine support arm,
  • Insulation element,
  • Connecting element to the body.

The material of high-quality engine and transmission mounts is usually a sophisticated mix of metals, rubber and plastics, which are optimally adapted to the needs of modern engines. In addition to the typical plastic and hydro mounts, there are also electrically or pneumatically switchable mounts and lightweight mounts made of solid rubber, which extremely reduce weight. The rubber spring is particularly important on the motor mount because it dampens vibrations, isolates noise during start-up, and facilitates the drive.

What happens if the engine mounts are defective?

Engine mounts are considered wear parts and should be kept in mind, especially on performance engines. If your engine mounts are defective, they can no longer properly absorb the mechanical vibrations of the engine, which you will feel in the form of vibrations (on the body, the gearshift lever and the steering wheel) and unstable handling, among other things. The noise that broken engine mounts cause is also very annoying. In addition, other components can also be damaged as a result, due to adverse friction and such. In the worst case scenario, the bearings crack and the engine moves uncontrollably in the engine compartment, which can cause immense damage.

The causes of a defective engine mount

The cause of a defect can be, for example, strong temperature fluctuations or extreme load on the engine. In general, high static, dynamic and thermal forces are permanently acting on the bearings. Especially if your engine comes along with a proper HP. Small cracks or breaks in the rubber parts of the bearings can then quickly cause major damage.

Replacing engine bearings

If you notice that your engine is bucking and your engine mounts are defective, you should replace them. Since they are wearing parts, repairing them is not an option. Most of the time you will have to replace all engine mounts (or even the rear gearbox mounts), as the wear is a similar one. What exactly the replacement looks like varies from engine to engine. It depends, among other things, on the design: Is the engine installed longitudinally or transversely? With a transversely mounted engine, replacing the rear bearings is usually more complicated than replacing the front engine bearings.

Step-by-step instructions: Replacing engine mounts yourself

Most of the engine mounts in our shop can easily be replaced plug & play. Simply follow the individual steps in these instructions. Depending on the brand and model, the exact steps may vary.

Step 1: First you have to lift the car or place it over a workshop pit.

Step 2: Now you can remove the oil pan cover.

Step 3: Go over the engine mount fasteners with a wire brush and some WD-40 and clean them.

Step 4: Now fix the engine with a hydraulic gear jack at the height of the oil pan, so that it cannot slip out of its position uncontrollably.

Step 5: Now you can remove the engine mounts step by step: The element that holds the bearing and gearbox housing together, then the element that connects the bearing and subframe.

Step 6: Now you can use a pry bar to loosen the engine mount bolts and remove the suspension.

Step 7: Now clean the mounting seat again with a wire brush and spray. Then you can install the new engine mounts in reverse order.
