ARP ultratorque lube? Sealant? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The LS flywheel bolts are spec'd at 75 ft lbs. Now comes the adventure.

They also are exposed to oil pressure, so you need sealant. So I got a new set of GM bolts and used ARP thread sealant, which has the same lubricating value as their thread lube.

As I was torquing the last one, it went. I hope it was the bolt and not the hole, I'm not 100% sure yet. Hoping the bolt stretched.

So I bought ARP bolts, and they say 85 ft lbs. They come with ARP thread lubricant, but not a sealant.

Should I use the ARP thread sealant that I have from their head bolts? I do NOT want a leak onto my clutch.
