Anti-sieze on lugs...

[DanielDudley]

I use AS on threads but not seats. I use it very sparingly, and do it once in the life of the car. I put it on the hub centric ring and wheel center as well.

[Mrmerlin]

I used it on the studs and concentric hub to prevent the wheel from seizing onto the hub, if the threads look dry i put on more,
never had a lug fail or back off if proper torquing procedures are followed.

Same goes for installing spark plugs a little dab will do yaa.

Its funny to get a car in the shop and cracking those lugs loose every one of them singing , yep the studs are dry as bone

That sez it...right there.

Some mechanics won't use Anti-Seize for certain applications.
What I learned the hard way with aluminum is to use it.
I put it on the lug bolts for my cars and use the torque values stated.
I use it on spark plugs and just about everything else.

You have to be careful with the plugs. You only need a small amount and you don't want to get any on the electrodes.


Permatex part #133K Anti-Seize Lubricant
For use on:
1. Brake lube assembly & anchor pins.
2. Engine head bolts.
3. SPARK PLUGs and Oxygen sensor threads.
4. Exhaust manifold studs.
5. U-bolts, LUG NUTS and spring bolts.
6. EGR fittings
7. Starter and alternator bolts.
8. Everything not mentioned in the above.

Use it.... it won't hurt.

For Al wheel nuts, Porsche says to use Optimoly HT (P/N 999 917 728 00) or Optimoly TA (P/N 000 043 020 00) recommended from 1988 (Optimoly HT and TA do not affect the tightening torque). The specified tightening torque is 130 Nm (95.8 ft-lb).
-- use it on the concave mating surface for the lug nuts & on the threads

I suggest anti-seize too, but I'll be a lone detractor. If Optimoly, like other anti-seize compounds, acts like a lube to provide more accurate torque settings, then it follows that friction between the contacted parts is reduced which changes the effort required to rotate the fastener.

If anyone is worried about overtightening a lubed lug nut, use 90 ft.lbs instead of 96.

I won't use any anti-seize unless it has proper amounts of ZDDP.

An then I need only 87.3oh4 ft-lbs of torque.

shaking head...

I have found that torquing lug nuts, with or without anti-seize, to pretty tight, but not too tight, works well. No problems so far.

I'm just passing on info from BA, and I think he was quoting a P AG TSB.

not an IMHO post, FWIW

[Flieger]

If Porsche says to use anti-seize, then says the torque spec is 95.8 ft-lbf, then that is how it should be done. No reason to reduce the torque unless you have more accurate data on your car's threads' friction along with the ball seat friction and so can evaluate the formula relating bolt preload to torque.

[RWebb]

yes - I have not seen the TSB tho...

[Britwrench]

Anti-seize as per the TSB.
17" wheels off the ground when torquing the wheel nuts.

No anti-seize on spark plug threads in Porsche engines.
