Galvanic corrosion isn’t your friend when you’re trying to change a timing belt.

In the Army, I dealt with stainless bolts in steel inserts set into aluminum skin on truck-mounted huts. The inserts stripped free in the aluminum more than half the time.

I don’t even have the luxury of steel inserts in this case (break ‘em out, press in new ones), and it has to do with the actual engine block itself.

Watch this. You’ll thank me later.

There was no luxury. Once they stripped, you couldn’t remove the bracket that they held down, and could not reach the insert. It sucked. And it was an Army shop, so we lacked any sort of special tools or, for that matter, serviceable
normal
tools.

Or this one. He gets it work a little better here. Tried it on my slot mags, it works a treat.

Damn. I thought they would have been designed in a non-stupid manner so you could just unbolt the other end of the bracket, pull the whole thing up by hammering on a slightly smaller socket than normal and then pulling upwards, and then just slice the bolt so the bracket is free. Then it’s just hammer or press a new insert in, line everything up, and then bolt it into place.

Luckily I haven’t broken anything yet, I’m still waiting back on a text to know what they want me to do with the damn thing.

It’s funny you use that video because I believe that particular S63 has that issue with the head bolts.

Yup, M156s until early 2011 were affected with that issue. That’s why if anyone buys a “63" engined Merc made early 2011 and prior, they should get ARP or Weistec head studs installed ASAP.
