OK, almost done! We have the four case bolts to tighten. Again, these are 6mm bolts and Porsche recommends 9.5 lb/ft. I added .5 lb/ft for my extension. I did the two bolts around the main seal first to make sure it was a nice tight fit. |

The final two bolts reside one on top of the engine case and one on the bottom. Again, 6mm Porsche bolts, you get the idea. Notice how shiny the new Balance Shaft Cover bolts are? |

It is all together now. Your bolts ar tightened and your seal is in but the car engine case looks like it was dragged in sludge! Take a non damaging cleaner and clean your engine case with a brush being carefull not to damage the main seal with any solvent type cleaners such as Brake Clean. And there you have it, a completed RMS repair. We will be putting up a clutch re-install shortly on C-Speed! |
Notes: Let me be the first one to say it is not as simple as it looks on these pages yet it is not as difficult as 99% of the internet will lead you to beleive. I am well versed around tools and I had a top notch mechanic beside me as I took the strides yet I felt pretty comfortable along the way.
Some things I do suggest however when you are doing this or planning on doing this:
1.) Replace your flywheel, clutch, pressure plate and throwout bearing while your transmission is wide open. This not only saves you time but it will also spare you the headache of doing this job more than once.
2.) Your new RMS is very, very delicate. It does not seem like it in your hand but any small nick or tear could cause the same problem again. In one of the steps earlier I showed final cleanup using an aerosol canister. Make sure it is safe to use around rubber products. (IE: Brake clean detioriorates rubber and is a No No!)
3.) Safety First! There were a few times when I was under the car with the mechanic and felt quite a bit more comfortable when we proped the engine up with a transmission jack and we used a proper transmission jack to remove the tranny. The key was that we had the tools. I wrote out this tech article to give you an idea of how to do it and what everybody is talking about when they say RMS. If you are not qualified, it is a lot safer and easier if you leave this to your tech.
4.) There is a reason why Porsche wants you to replace certain bolts. It is in your best interest to do so. Failure to spend 10-20 extra dollars here and there can cause transmission failure in the future and that cost is far greater than 20 dollars!
To conclude this Tech Article I would like to thank a few people that allowed me to make it happen.
Haigo Madadian at High-Tech Automotive in Vancouver B.C., Canada. Without his knowledge and expertise I would not have been able to do this. (Did I mention his tools?) Website Coming Soon
MCL Porsche Vancouver: Gordon Mennie in the parts department who has given me all the parts I have ever needed exactly when I needed them. Gordon Mennie
Every Porsche nut out there like me. If it wasn't for you guys I would have no legitimate reason to work on my cars. I will continue with these articles as long as you guys want!
