We have a 340 and attempting to remove the torque converter to place engine on stand. Have not obtained working wrench to get at two bolts. Engine will not roll around with heavy weight on damper bolt or converter. Any ideas or warnings.
Thanks

take the spark plugs out and spray some Marvel Mystery oil into each cylinder. maybe some wd40 as well. spray in several directions in each cylinder, you want to try to soak the walls down.

allow to sit overnight and then give it another go.

if you can't get the engine broken loose i'd just pull the trans and engine as one unit.
 
If that picture on your post is the current status of what you are working on. I'd say your best bet is to pull the heads and start soaking the cylinders, or drain it and roll it over and pull the pan and all the rod and main caps, after numbering them of course, and pull the crank and converter out as one piece. They will be easy to separate at that point. Some engines will never free up, no matter how long or with what you soak them with. You just have to start tearing them down and deal with the parts that are stuck as you come to them. Some times big hammers and cutting torches are involved.
 
Slow but steady

Thanks guys, going to simply go at it area by area, inch by inch. I really wanted to turn it so I could get to the bolts for the converter but managed today. Now at least we have it on the engine stand.
:hurray:
