ARP Thread Sealer vs. Assembly Lube What is the difference between them? I only thing I can tell is that the assembly lube has a higher heat range. Also, what is the difference, if any, between ARP stuff and GM's Lock Tight? TIA.

Re: ARP Thread Sealer vs. Assembly Lube All the thread sealers I have seen, to include GM thread sealer with teflon are normally used on the head bolt threads that go into the areas of water jackets in the head. This keeps the heads from leaking coolant after assembly. Thread sealers are a lot like that white pipe sealant that plumbers use.
Engine assembly lube is VERY different. Its used when installing rod / crank bearings, etc.
Whatever you do, dont assemble bearing surfaces with thread sealer, and dont use assembly lube on head bolts, etc that require sealer do to water jackets. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Can't speak for "ARP" sealer, but I am sure its like the GM thread sealer.
Anyway, they have two completely different purposes and are not interchangable.
Ron,

Re: ARP Thread Sealer vs. Assembly Lube BTW, "Lock Tight" is something again different from assembly lube and thread sealer.
All these 3 compounds have a different use. It has nothing to do with the "heat range" you mentioned.
If and when you start into your engine, I would highly recommend you get some expert help prior to using these various compounds.
