Rotating Engine ? UPDATE
Guys I am trying to figure how you guys rotate your engine while still in the car. I am putting in new rockers and doing the rotating each cylinder EOIC method. I just cant figure how to rotate the engine. I no all the spark plugs have to come out.. I am assuming an 24mm socket but I don't see that fitting in the crank area. Is there an easier way.
update: I took a 24mm wrench and heated it up and bent it to shape and now it clears the rack and opinion and slips right on the crank bolt. So what I will do next, would be take the plugs out and put the car into neutral. thanks guys for the help.

Grab the serpentine belt and pull it. OR If you have a MN6 trans, put it in gear and push the car, take it out of gear and roll it back, repeat..

1. When an operator remove materials off, furthest from the chuck, at the socket's end face, it is called - "facing off".
2. When an operator remove materials off the O.D.(outside diameter), than, it is called - "turning down".
When facing off a socket for this application, faced off by half is taking things a little for granted!
Well, for me, depends on whether the socket is regular, impact, industrial, deep walled or..... Bottom line - depends on the style of the socket design. Then, I measure for the total with consideration to ease of install/removal, clearance for the turning tool combos and such.
I hope that didn't complicate things, but clear things up a little.

The easiest way I know of. You can go to the parts store and buy the starter relay that goes into the fuse box under the hood. You can then remove the protective cover off of the relay. You need to replace the relay that is in the fuse box with the one you removed the cover off of. When you are ready to bump the engine over, you just manually make the contacts touch.
Enjoy.
Enjoy.

^^^Still Hit & Miss. That method only gets into the neighborhood.
Accuracy = manual turning + travel dial indicator to show exact travels in .001" or .0001" - of course, that all depends on how accurate you want.

Bumping can get you close. Since LS has non adjustable rocker arms -Lots of people also R&R and torque their rocker arm bolt without following the "EOIC" procedure as well. Logical, right
? Do whatever make you happy!

^^^works on some engines but not all, especially engine having good internal tolerance. But easy to find out!
Didn't work on my lowly low mile '05!

Op, I can post pic on hand tools I used on crank. After removed coolant hoses and air intake snorkel, I turn engine from the passenger side, which had the most clearance and it was easier for me to hook up my assortment of Starrett "C" clamps and such, along with travel dial indicators on #6 to monitor, while slowly rotate for precise "EOIC" sequence. But you do need to be resourceful while "C" clamping used for travel dial anchor.
My method might be presumptive - do you have Starrett type "C" clamps that used for dial indicator attachment and two long travel indicator?
If you are lacking resource, but still want to get fairly close, wooden dowel or TDC Stop Indicator can help.
Go ls1tech forum, lots of fun reads, if you want more ideas!
