Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

    FWIW, at least here anyway, Napa or other parts stores will rent out the necessary crank holding tool if you dont have access to air tools. They come in handy, definately.

    Air tools, especially with balls, are definately the way to go though.

      you're shitting me right? stuffing random shit down the spark plug tube? how would you even come close to thinking that is a good idea?

      back on topic...
      like was shown above, i also stick a thick craftsman screwdriver (lifetime warantee!) into the timing hole and jam the flywheel. i've never had a problem getting my crank bolt off, but i have a good impact gun to remove it and then torque mine to the proper specs whenever i re-install it.

      if you are having a hard time, a combination of penetrating lube, a couple good smacks with a nice big hammer, oxy-acetelene, and making sure you are turning the right direction will help with getting the bolt off.

          Ive heard from several techs to heat the bolt up till its red hot then walk away. They say it stretches when its hot and after it cools its not as tight. Ill find out soon enough. Ive got 2 in my driveway to do real soon.

            i too had the same issue and used heat impact as well as breaking impact sockets. hope it helps if what i did was wrong please correct me and explain why it was wrong but at the same time it did work finally.

            It would work. For example, stuffing Nylon rope into the cylinder from the spark plug hole is one method to take up the space in the cylinder and prevent the valves from dropping when doing work like replacing the valve springs. I would be concerned about using that method to stop the crankshaft though because of the possibility the wire or rope could get somehow get behind the valve and cause it to not close completely as the pressure from the piston and the compressed rope/wire press against the top of the cylinder. If it wasn't closed completely/had rope or something behind it then it would likely get a bent stem. (I'm presuming he used insulated wire and with no metal exposed top the cylinder wall, top or piston--also I would check to find out if the copper wire is softer than the aluminum in the cylinder. Of course if its rags or nylon or polypropylene rope you're using then that definitely is not going scratch anything).

            It wouldn't be my first choice of method though unless I knew the geometry of the cylinder wall and top--which I don't as I've never had the head off of the engine. Also, are the pins on the connecting rod ready to take the force of that 400-500lbs/foot that might be required in an extreme case of a stuck crank bolt? (I'm not saying they wouldn't take it but just that I don't know).

            Sounds like it has worked for Heffe55 and that he's done it more than once!

              I'm assuming putting the car in a high gear so the flywheel doesn't move wouldn't work in this case?

                technically it could work and isnt a bad idea, but we are (or at least i am) assuming that you have the car in the air and one or both wheels off the car. that method wouldnt work in that situation.

                  Would putting it in a high gear work if one of the front wheels was on the ground?

                    No because the diff will just transfer the rotation to the other wheel.

                        HOLY crap. I didn't read all the posts, but me my bro and dad just spent the entire day changing the timing belt, balancing belt, water pump, and all the belts cause we were there, and the crank bolt was stuck. HARD.
                        After trying for over an hour using a 600lb in reverse impact gun and mapp gas torch to heat it up, we went and rented a 3/4 inch impact gun that was a HUGE HOG. After heating the shit out of the bolt and harmering the shit out of the bolt with the new hog we rented it FINALLY came off. Oh man...that was crazy. I'll post pictures tom..
