TORQUE spec'd for spark plugs?...

[fixizin]

Yep, I checked the Tech Lib first, only torque specs listed are for the "important" stuff (head bolts, rod bolts, etc.)...

... finally getting around to doing this @ 92k miles... been procrastinating since 83k miles.

I ask because, strangely, Cylinder #2 plug has broken (the actual electrode, deep down by the hex) TWICE on me over the years, wondering if it was over-torqued at the factory (robot?), then over-torqued by ME when I replaced it the first time?

Thanks in advance!

With spark plugs, there's not really a torque setting, because you just seat the spark plug and cinch it. Just a half turn, or until it resists a single-handed turn before you're cranking on it.

7-15 ft lb is standard....which is what seats the washer if equipped...high side on re-use

I wonder if my still-shiny mid-1980s Craftsman El-Wrencho-de-Torqo even goes that low... checking... Jeopardy muzak... it DOES!

Now I just gotta get my AutoZone loaner Compression Tester and surprisingly hi-res TEMU borescope sorted out...

... Clear Flooded Engine mode will be getting some use!

On the 4.6l I had, it didn't matter. The darn things would back off enough to leak. The pressure blowing back would push the plug wire/boot off and I'd have a mis-fire.

I hated that engine and don't ever want another one.
