Sill Plate Repair in back Corner of house 2x4

Could use some advise on repairing a piece of sill plate in the corner of my garage . Its 2 x 4 sill and its rotten and a hole through to outside.I noticed this when i was replacing the banged up asbestos tiles on the outside. (for some reason the whole bottom row of asbestos tiles on the back of the house was broken or Cracked needing replacement). The house was built in 1964 so I'm sure there are areas of sill plate 2x4 needing replacement. I would like to do this myself and save $ being christmas is near and have 4 kids, no 5 i forgot the wife.I know i have to jack up the whole corner slightly to install new Pressue treated sill 2x4 and sill tape. the area is only 2 feet I'm attempting for starters. Theres a bolt coming up from the block with nut to tighten the sill plate for sturdiness and so it won't shift. How do i get the stud under the vertical 2x4's with the bolt in the way?? I don't want to move 2 or 3 wall studs out of the way because that would involve cutting the screws or nails that hold the sheathing or wallboard. Im thinking the only unobtrusive way is to notch or cut out 3/4 of an inch of new sill , enough for the pressure treated new sill to slide in onto the bolt,hammering it in place from inside the garage.There is no sheeetrock on inside wall in garage , waiting to repair this first before finishing rock. Any suggestions gents ??

I think you have to cut the bolt in order to lift the wall enough to slide a new plate in.
How are you jacking the wall? At the rafters above? Is there a sill plate and a bottom plate for the stud wall?
I wouldn't worry about cutting one anchor bolt, but a bolt near the corner should be replaced. Possibly with an expansion anchor into the same cell.
You still need to cut some nails between the sill and bottom plate even if the sill is rotted.
A pic would help.

You'll need to put the pictures on a hosting site like photobucket or flickr then post a link to it here. Uploading pictures here doesn't work. (And if you did manage to make it work, the site shrinks them to thumbnail size so we can't see detail.)

There is no need to cut the foundation bolt!!!

Remove the damaged section in pieces, cut it from around the foundation bolt, leaving the bolt intact, removing the nut and washer, of course. Cut your replacement material to length, then notch it to fit tightly around the bolt, then when it's all back together, reinstall the washer and nut. It's that simple.

One thing you're likely to find is that 1964 lumber was thicker than today's material, if this is the case, then you're going to have to shim the new material to the proper thickness or find suitable material of the proper thickness. Keep the pressure treated against the cement foundation, add your shim stock between the new plate and the house framing. It does not have to be one solid piece of shim, you can shim joists individually.

You're right, much better to remove the nut and washer. Still a little groggy from all the turkey and stuffing.
Spruce has the right idea.

Here is another good piece of advice, if you have never done this type of work: Don't DIY. A bad job will cost you a lot more.

If you need to, save money aside (if it's possible, with your large family) and hire a pro when you're ready. But don't postpone it forever.

Ask yourself: What's more important than having a good, solid, trouble free home, Chrstmas time or not?

Careful using that car jack. They are rated much smaller than a "house jack" - typically a hydraulic bottle jack or screw jack. If you put too much weight on it, and it fails, you will have serious potential for structure damage and someone getting hurt. See if you can borrow a house jack from someone.

A 5 to 10 ton bottle jack will suffice for what you are doing. Larger is ALWAYS better, then you won't every be worried about overloading the jack or not being able to do what you need to do. A 12t jack will set you back about $40 to $60.

A "house jack" is a 10 ton or larger hydraulic bottle jack.
