Exhaust manifold broken bolts

[Nilao]

I can pull the turbo on my 871 in about an hour including dropping the coolant. I got very good at it when my oil filter header plate got a pinhole in it and I was replacing gaskets trying to find it. I pulled it 6 times over 3 days lol. It was elusive as is was behind the turbo but would only spray coolant up onto the bottom of the egr cooler once the truck was up to temp and pressurized.

So I'd say 4 hours to drop the turbo pull the manifold and reassemble. Add a couple hours for extracting bolts, replacing o-rings, cleaning things up and torquing to spec
