Torque arm mount torque specs

[sidepipe]

Does anyone have the torque specs for the torque arm mount (not the torque arm) on the Cayenne S v8 engine?

[Doug_B_928]

For the first gen Cayenne, engine torque support bracket bolt that’s accessed through the headlight opening is 44ftlb and the other bolt that is accessed in the engine compartment is 37 ftlb plus 90 degrees.

Thanks Doug, but I am talking about the bracket on the engine that connects to the torque arm. It’s attached to the passenger side cylinder head via two upper e12 bolts and two lower e10 bolts. See attached. 
 

anyone have any torque specs for those bolts attaching the bracket?

[Doug_B_928]

Oh, got it.  Sorry, I looked and I don’t have those values.  

[sidepipe]

Thank you anyways :)

Anyone have any info on my question?

The correct torque specs for the toque arm mount are:

 

E12 = 23nm

 

E10 = 10nm

Look at the head of the bolts.

You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts are categorized by grade and metric by strength class.

Thanks everyone for the help. I will eventually be posting pictures of torques specs for the bolts in question. (see above post from me)

 

So I performed a spark plug and ignition coil change and on two of the plugs a deteriorated light green o-ring or seal came out of the area where the spark plug seats itself on the cylinder head. I could not find any mention of this anywhere on the Internet. The car has been run 50+ miles since the change and everything seems to be working fine but if spark plug seals are meant to be replaced then I will buy them. Please advise.

I could be wrong but upon further investigation it looks like the original plugs had some sort of seal on them (I have a low milage Cayenne S)? See attached picture.

[sidepipe]

Actually after looking at the seal it is too big to be the above picture. Any help would be appreciated with this. Thanks!

[Loren]

All spark plugs come with a sealing washer - no other seal should be used.

Use care to not over torque the spark plugs as you can crush (and even fracture) the seal.

[sidepipe]

Thanks Loren! I am not challenging whether you are right I just don't know what this is (see attached) meant for? I have looked at schematics and couldn't find anything unless I overlooked it. Any help is appreciated.

 

The ring in the picture came out of the spark plug hole when I was removing the spark plug. I have a low milage Cayenne S and I believe these were the original spark plugs from the factory that I replaced.

That looks like a spark plug tube seal.

I can't imagine how I could get this seal back in the spark plug tube and have the seal seat itself flush when applying torque to the spark plug. The car has been running fine without two of these seals, if I need to replace them would you happen to know where I could purchase them and if there is a how-to?

The plug has nothing to do with that seal, it should go under the plug tube itself, not the plug.  We get them from a dealer.

Several questions:

 

Are there pictures illustrating where this part goes?

 

Would you happen to have the part number?

 

Is it okay to run the car without a couple of them until I can get the part?

Is there a how-to on how to replace these seals?

I don't have a step by step, Loren may, but you can probably find one online.  And changing them out requires removing the valve cover, which entails removing the air boxes, the air pumps, the torque arm, and a whole lot of other stuff as well.  Definitely not a fun job.

 

 

The more I look at your picture of the seal above, the more I am inclined to say it is a tube seal for one of Porsche's flat six engines, like the 996.  The Cayenne tube seals are a bit more flat looking, and if one or more were missing, the plug tubes would be full of oil, which you have not mentioned:

 

I'm now wondering if someone mistakenly put the flat six seals on the plugs that are in the car for some unknown reason.

I am in possession of a new set of spark plug gaskets and they are too big to be the small green seal.

I was looking at this seal before and don’t think it’s the same because of how thin the light green one is. 
 

If oil was getting on the spark plugs wouldn’t there be white smoke and a metallic smell from the exhaust?

[Loren]

Correct - and the spark plug seal in a split metal ring - so it is a crush seal.

Leaking plug tube seals flood the plug tube, the oil doesn't go into the combustion chamber, and the plugs would come out dripping with oil:

 

[sidepipe]

I have driven the car 100 miles since the spark plug and ignition coil change; from what I can tell there is no smell or smoke coming from the exhaust and the car drives fine.

 

Loren, would you happen to know what these green seals could be?

[Doug_B_928]

If it were me, now that the car has been driven a bit sans mystery o-ring, I'd pull the plug and inspect it to see if it has any significant amount of oil on it as per JFP's photo.
