ARP Headstud lube

Whiteghost 2.5 · 08-13-2007, 11:59 PM

I do not have any of the ARP lube that came with my studs, what can i use on the nuts when I torque them down other than the arp lube? Can I use engine assembly lube?

Thanks

Josh

I have used lubriplate in the past no problems.
oh did you get my PM about the body kit?

Check w/ your local machine shop. They more than likely have some. I was going to do mine dry as they come with specs for dry and lube, but I was advised against it.

I usually just use regular motor oil. The oil will get in there anyway once the engine is run.

+1 for motor oil. I think the FSM actually calls for it.

Don't use synthetic motor oil - it's so slippery you could potentially stretch the studs. At least, that's what my "Building High Performance Mustang 5.0s" book says...

lol you cant be serious. if you torque to spec theres no way to stretch the studs.

Devan M · 08-15-2007, 04:50 PM

I would contact ARP for the torque speck to use with the lubricant you choose.

You can use 5w-30 regular oil. I believe it says on the box what to torque the studs to when using motor oil instead of the arp moly. I think they say like 72ft/lbs for the arp moly and i am gonna take an educated guess of 84ft/lbs. for oil

you could stretch the threads no?

The angular torque method that subaru specs is actually the most accurate as it discounts the frictional losses from different lubricates. Now if we could just get arp to give us specs like that!

From ARP's own website (URL available upon request - I don't have enough posts for NASIOC to let me post links)

2. The lubricant used is the main factor in determining friction, and therefore, the torque for a particular installation. Motor oil is a commonly used lubricant because of it’s ready availability. If less friction is desired in order to install the fasteners with less torque, special low friction lubricants are available. With special lubes, the required torque can be reduced as much as 20 to 30 percent. It is important to keep in mind that the reverse is also true. If the torque value has been specified for a particular fastener on the basis of low friction lube, installing the fastener with motor oil will result in insufficient preload; the torque has to be increased to compensate for the extra friction caused by the motor oil.

The problem is depending on the lube used, the torque specs change. Therefore, the torque specs for motor oil are higher than the torque specs for synthetic lube. I misspoke by saying not to use synth motor oil - it can be used, but only if you have torque specs for that oil. I guess this is why ARP provides their own lube, so that they can definitively give torque specs.
