Anti-Seize or Nah?

[someotherguy]

I don't know. There are some engines that have a reputation for spitting out spark plugs, I definitely wouldn't use it there.

Pretty sure those were the Ford Triton engines that used a 2 piece spark plug. They would blow apart and leave you with the threaded portion stuck in the head. Solved by newer 1 piece plugs.. after you fight the old pieces out. Or push the Ford out into the street and light a match on it.

We use a **** ton of antisieze at work on the bolt up flanges. No torque specs, just crank that ***** tight in pattern like a wheel. When I worked at tire shop people always thought the wheels stuck cuz we didn't use antisieze on the studs. They couldn't understand that the wheel was stuck to the hub. Boss explained it to me when I first started. We even had customers say their wheel came off cuz we didn't use antisieze on the studs... uhhh what?! NO it's cuz we told u to come back in a few days later so we could retorque the aluminum wheels but you wouldn't. People aren't smart.

The Oldsmobile "Rocket 88" aluminum heads had an issue with blowing out plugs too. Then you had to drill out the plug hole and either tap it for a bigger spark plug or heli-coil it.

And you're in Ohio, so the aluminum wheels were probably a little corroded to the hub too, from road salt?

Oh very much so. Wasn't usually too bad cuz some people would religiously want their tires swapped out on specific dates or they'd have a steel set. For winter... the few rare smart peoole.

And yet it's supplied with new O2 sensors to be install in OE stainless head pipes...

Aren't the OE manifolds cast iron?

Yeah but the rest of exhaust stainless

In the gmt400 world only TBI's will have the O2 sensor placement in the manifold, and not all of them are this way. The last couple years with heated O2 applications place them further downstream, and even some non-heated O2's are downstream as well - I was puzzled to see my '95 3500HD 7.4/NV4500 had a non-heated O2 downstream near the cat.

Doesn't really matter that the oil/grease base cooks away. It'd do that on, for example, high-temperature exhaust fasteners, too. But the metal particles remain, acting like micro-ball-bearings come time to disassemble.

Fair point - I'd forgotten I use it on exhaust fasteners and the like.
I have another preferred lubricant for where there's a moving component within an exhaust system eg, turbo waste-gate. It is an anti-wear additive (that can withstand 1900F) suspended in kerosene which flashes off at temp and leaves the anti-wear additive behind to do the lubricating. But this is as far away from Pitman arms that I should get my coat...

I use it as much as possible. Especially on gaskets. The next time you have to work on something the gasket peels of with two fingers with no scraping or chipping. And no it doesn't leak. RTV is only needed when your mating surfaces are pitted or corroded.
