Default Need help & info

Hello everybody. I don't know if anyone remembers but I was on here a little while ago because I got hydrolock and had some question about head gaskets and such. Well know that I've got the heads off I've come to find out that I can't move the crank shaft. In my Haynes manual it says that I have to take the Piston heads off before I can get the block (bottom end) apart. Well here in lies the problem. I can't move the crank shaft to get access to the piston pins.

Well, I've tried to remove the bolts that hold the block together but they seem like they don't want to break free. I'm afraid to use a breaker bar because my impack wrench hasn't moved the bolts either. Now what I'm asking is am I doing something wrong or missing a step because the manual is very vague and doesn't really answer a lot of questions that I have, and if I have to remove the piston heads who am I going to do the when the crank won't move.

Not for nothin', but I don't think North America offers much traffic through here between 2AM and 5AM eastern... give 'em a chance to wake up, man!

Try harder. They're tough to break free. You'll need an extension on a breaker bar (like a pipe fitted over the breaker bar handle). Or you can just use the breaker bar and be ready to pull hard.

With the oil pan removed you should be able to see the crank. Try undoing the connecting rods from the crank and pulling the pistons and rods out together. Cover the connecting rod completely with a rag or something so it can't touch the cylinder walls. This may work for one or two, but if you can't rotate the crank you will not be able to get to them all. You may get luck and be able to get the bent one (if it is) out and then do the rest at the pins. Removing the pistons out the top will break the rings. Don't worry about that hey were not broken when it was running. Unless you see score marks in the cylinders.

Have you tried rotating backwards? If you bent a rod it may be hitting the block and that may be why it will not turn. Any metal in the pan?

I guess it may help to know if the engine is out of the car or not?

Good Luck!

Peace,

Greg
