How To: Porsche 911 Engine Mount Test and Replacement
Вставка
- Опубліковано 21 сер 2024
- A step by step video documenting the replacement of the engine mounts in my Porsche Carrera 4S. Overall this isn't a very difficult project, but I ran into a few issues you can avoid.
First - order a replacement set of nuts as well. Mine were corroded and difficult to remove.
Second - before trying to break the 18mm nuts loose, squirt them with some penetrating oil (I used some garage door lubricant) and let them sit a few minutes. This will make your life MUCH easier.
I could have edited the video down a bit more and glossed over the trouble spots I ran into, but I decided to leave them in for entertainment purposes and because I felt it captures the true nature of the project a bit better.
Here is the link to a great Pelican Parts article that outlines the procedure: www.pelicanpart...
Hope this helps someone out - please feel free to post any questions you have!
Thanks! This video was a great help. It actually made my day.
Nice vid.I did motor mounts on my '01 996 a while back. Super easy, took 45 min. I would like to add ... blue loctite and Harbor Freight are your friend... A metric deep socket set from Harbor Freight will run you about $15 and includes an 18mm deep socket. Torque spec on the 13mm upper bolts is 25 ft/lbs and the 18mm main nuts is 63 ft/lbs. Loctite blue on all is a good idea. Also it is important to note to be sure the square part on the motor mount drops into/lines up with the corresponding square hole in the body when tightening. You know it's right if there is the same amount of stud coming past the 18mm nut as before.
Thanks for including the breaking of the tool and some of the workarounds you had to do due to the stiff bolts - makes me feel better about my own experiences.
Haha yup, happens to the best of us. If anyone claims they don't run into snags on these types of projects they're either extremely lucky or they're lying.
Love the lobsta wheels on the 996! I replaced my engine mounts last summer and it was a noticeable improvement from the get go. Great video and great looking car sir!
Thanks!
@Porsche911luv please could you let me know what improvement you noticed? I'm about to change mine and just curious? Thanks :)

An impact driver should work great for this. Thanks for the video
Thanks for the video. DId you notice anything different while shifting or driving around? Could you tell that the mounts were changed without looking at the tail pipe?
Hey Michael. I didn't notice any differences but others have said that they do.
Thanks, I also did not notice anything. There was not even a significant dimensional change with the difference between the tail pipe and the rear bumper . Oh well
Thanks for the informative video. Going to be doing this on my 116k mile 02 C4S.
Glad it helped! Let me know if you run into any questions/problems doing yours - good luck!
They must have made 1,000,000 silver 996s… I have one and looks like every one still running is silver.
There were actually several versions of silver. This one was a warmer color of silver (Arctic Silver Metallic) but there was also Polar Silver which had a more cool/bluish tint. It's kind of Porsche's signature color - and monochormatic colors are exceedingly popular amongst car buyers across the board. But, for German cars - silver is the official race team color of the country (Itay's is Red). I'm a big fan of the crazy Porsche colors like the blue / orange / green / purple / etc - but in the end it's tough to beat just how sleek and classy a silver Porsche looks.
@@charlieaf92 Arctic Silver is what I have… and what I see all the time. Maybe because I own one I tend to see it more.
PB blaster woulda solved the issue for 10 seconds lol
I have the same car, 2004 996.. have you noticed any difference in the shifter? Mine is a bit stiff, especially when the engine is cold, so I'm wondering if changing the motor mounts would help? The clutch was replaced about 6 months ago, and I already changed the manual transmission oil thinking that would fix it, but it didn't make any difference.
Hey Kevin. Honestly, I did not notice any change in shifting - it was smooth prior to the mount replacement and smooth afterwards (manuals do seem to shift better once they're warmed up though - I notice this slightly in my 996). However, I've seen other 996 owners say that replacing their mounts made a big difference in the shift quality. I'm assuming it just comes down to how worn your mounts are. If you're pretty confident they're shot - it makes sense to start by replacing them. If your stiff shifting persists, I'd look into lubricating the shifter linkage and bushing in the shifter itself.
charlieaf92 I'm actually going to give this a shot. I ordered the Rein engine mounts from pelican parts at $180.00 for the pair including the hex nuts, but I will take a closer look at the linkage, thanks :-)
Sounds like a plan - good luck!
These cars are known for stiff shifts when cold. Worn mounts will make your shifting "clunky", like in a hard pull from 3rd then into 4th you will feel the shifter be kind of pushed forward. Honestly, at 100k plus, just change them and the transmission mount, they are a wear part, like bushings.
do u race? r car fast 2 furyus?
jdorbit Do you offer drifting lessons? Particularly after golf and some supplements?
Is it the same part left & right?
I believe so, but its been a few years. Best to double check with your Porsche dealer or part supplier.
@11:06 That's what he said.
