I see what your saying, but really, almost $250 in labor for something that took me 15 minutes?? Unclip the fuel line from the rail, unclip the sensor and then reconnect. I could see 1 hours labor at a minimum, but not $250.

Aluminum expands and contracts at different rates than cast iron, which expands and contracts at different rates than high strength steel bolts/studs. Add in some galvanic corrosion and extreme heat cycles and you've got a lot of stress. Maybe even stress corrosion playing a role. Or maybe they just spec'd out the wrong kind of fastener. Something too strong may be too brittle to survive the heat cycles and varying CTEs over time. Something too soft that easily survives the varying CTEs may not have enough ultimate strength to survive.

I assume the truck manifolds might be thicker in the mounting area not allowing them to expand/contract as much as the car manifolds.

I agree, but why the issue on the 6.0L and not the 5.3L? I haven't looked into the differences between the manifolds on the 1500 vs 2500 but it is still odd in my mind...especially for how common it is on a 6.0L

Labor rates here (according to my shop owner, haven't checked) at dealers are around 170-190 an hour.

I see just as many broken 5.3 bolts. Most commonly the Driver side rear bolt. Followed by pass rear, then drivers front. Manifolds and I believe y pipes are all the same.

Interesting. I've never seen a ticking 5.3L on the roads, but everyone I know with a 6.0L has or had the issue. I'll keep crossing my fingers for my 5.3L. Coming up on 290k miles now

That's insane, hard to believe people wouldn't just hit the independent shops to save some cash. But even at $190 an hour, they are still grossly over charging for the job.

I think the dealers by me charge $125 an hour.
