Installation of Rein Automotive AVE0382P Engine Mount

Hello, this is my first post to the 996 forum. I bought my 1999 996 tiptronic about three months ago and have enjoyed it. It has 36,000 miles and right before I bought it, the previous owner had all the problems fixed such as the IMS bearing changed, rear main seal replaced, starter switch replaced, and oil changed. I have spent a lot of time reading this forum and the first job I tackled was replacing the motor mounts. I used the rein automotive mount, purchased from Amazon and they fit perfectly.

I started with jacking up the 996 on the rear jack points under the frame, and I placed the jack stands under the rear stabilizer bar, one side at a time. This was the safest way I found standing up the vehicle. Once I placed the vehicle on jack stands, I supported the engine with a 2x4 under the oil pan. Then I removed the underside motor mount one at a time starting with the right side first. You will see in the picture the elongation of the motor mount. I removed the device that was in the way on the left side of the engine and installed the left motor mount. The small 13mm bolts on the motor mount top side were torqued to 25 ft lbs, and the bottom bolt holding up the engine was torqued to 64 ft lbs. I put everything together and drove the car. It made a pretty big difference. The motor mounts were original in the car but manufactured in 1998. The new mounts were manufactured in 2014. When I drove the car fast with the original mounts, there were a lot of vibrations and rattles. Pretty much all of those vibrations and rattles have stopped. The car also drives much smoother now. My car did not have many miles on it, but the motor mounts were worn needing replacement.

Here is a picture with the rear cross member being supported by two jack stands.

This is a picture of the motor mount on the right side. The air cleaner has been removed. Nothing further has to be moved to remove and install this mount.

Picture of motor mount removed from left side. I am holding the emissions pump in my hand which had to be moved. This is held in by three bolts. It is easy to remove and swing out of the way.

This picture shows the old motor mount next to the new. Typical elongation that I have seen in other posts.

I live in Germany, and fortunately I get to travel the autoban every day to test out the Porsche. At 100 MPH, the car is very smooth with the new motor mounts. I will try it out at 150 MPH when I go to work, but I am confident the car will ride smoothly. These motor mounts are a great improvement!

Welcome aboard! Love that color combination. Good job on the write up.

Do you have a picture or pictures showing how you support the engine? Thanks, and welcome to RL. Must be an entirely different experience being able to drive at 100mph let alone 150 mph. Legally and in 'traffic'.

This picture shows the engine being supported by a 2x4 under the oil pan. This support was good as it did not damage the oil pan and there was no creaking when I jacked up the engine. Just jack up the engine enough to take the tension off the motor mounts. Only remove one motor mount and then replace it with the new one before installing the second motor mount. When you replace the motor mount, torquing the nut will take up the slack between the rubber motor mount and the engine support bar. Torque the 18mm nut to 64 ft lbs.

Thanks, thread bookmarked for future reference!

318touring, It is pretty impressive that a 996 base model from 1999 will go 150 mph and I regularly cruise at 120mph. 150mph is too uncomfortable for me regularly, unless there are few cars on the road. These cars a light, aerodynamic and have a lot of horse power for their size. I have always thought that when I get the car back in the states, I will miss driving autobahn speeds. The other thing I have not tried yet is tracking the car as they have the N�rburgring track where you can compare your times against other cars of the same make and model. If you google porsche 911 on the Autobahn, you will see porsches going 180mph (300km/hr). Things just come up too quickly at that speed on the highway.
