ARP assembly lube our thread sealer?
ARP assembly lube our thread sealer? Hello yall I am in the process of installing my head. Do i use The ARP thread slealer our ARP asembly lube? I cant find anything that says ARP moly lube. Will it be oky use the thread sealer?
i think the assembly lube is the moly lube......is it the arp #903??i just ordered arp moly lube from thunder and it says assembly lube on the tube.Thats what you should use with arp head bolts,not the thread sealer.
Okay it says this on the back of the tube part number 100-9904
APPLICATION
Clean part thorouglhly in solven with a stiff brush. Clean cylinder block threads with solvent and an engine brush of the proper diamter. If needed us a thread tap to clean out cylinder block threads. Apply an adequate amount of ARP Thread Sealer to the thread and screw fastener into place. Wipe off excess selant. Place gasket and cylinder head in place. Lubricate under side of the bolt head with sealant and torque according to instructions supplied with the kit.
So is this okay to use our what? I used this on both side and the driver side is fine with no leaks should i take that side apart to use arp Asemebly lube instead of the thread sealer i got? I reall want to leave that side alone.

why dont you just use the right stuff???And if you dont have the right stuff(moly lube)then use motor oil and torque to the correct spec with motor oil,the thread sealer is a no no and will make it much harder to clean up the threads when you have to do this again.If you want to spend hours upon hours chasing threads gummed up with thread sealer,then use thread sealer.

Ill try wait for more people to post up and ill probaly just run it. Still thinking. i dont want to use the motor oil because the torque seems too high and somone said they broke one bolt trying. Last edited by LS1FIRE; Mar 18, 2006 at 07:45 PM.

you should be fine with the motor oil,just dont go to the full spec if your worried,but if someone broke an arp head bolt its not because they over torqued it,but they probably put to much side load on it,if your worried about it then wait until you get the moly lube the 903,i dont know why tsp would give you the sealer with the head bolts,probably just a mistake.

The ARP thread sealer is also a TQ'ing agent. It also dosen't harden, but can be a pain to clean up. If the other side is working fine, use the same procedure and check TQ after a couple of warm ups.
arp supplies tq specs for using the moly lube or 30 weight with their head bolts...probably all their bolts.
i'd use the moly lube...why buy $160 bolts and not the $6 tube of lube?

Sounds like TSP grabbed the wrong tube. There is a section in the ARP Sale Brochure on using the sealer, you need to download the pdf file and then I think it is at the end of the stud section. It may be of some use if you plan to use the sealer, you have to torque the fasteners before the sealer sets up. I also wouldn't re-torque them later.
At the end of the day, the critical item is to get the stretch correct, and they are using torque to determine stretch rather than rotation like GM uses on the stock bolts. Torque is based on friction and that is why they are so particular on what gets used on the threads. Rotation is less dependent on friction.

if you got arp bolts/studs, the idiot sheet for them should tell you what to TQ them to with their moly lube (they send a small tube of it in the box) and with 30w motor oil. thats just from my experiences though
