some people use a socket and rachet to rotate the crankshaft when making valve adjustments and you have to turn counterclockwise for a honda engine. if you rotate the crankshaft counterclockwise, is there a limit on how much you could rotate it? coz when i tried rotating mine, it lets me rotate only about close to 1 turn and it won't move anymore, i didn't try harder anymore coz i'm afraid i might break something. is that normal? or should the crankshaft keep on rotating as long as your turningt the bolt?

i did mine while the front is on jack stands and tranny in neutral.

 

keep going.
it gets harder/easier at certan points.
remember you are moving 4 pistons and a heavy crank. not to mention cams and valves connected to springs.

 

take the plugs out and it's easier..

 

I rebember when I first got my swap i tried to turn it with the plugs in the I almost tipped the motor over on my foot.

 

<---done it. But with a V8. Luckily it only pinched my toe..

 

so you guys are saying that it should turn all the way no matter how many?

coz when i first turn it counterclockwise, it turned very easily without having to exert much force. then after about 1 turn, it just won't move anymore, not one bit like something is blocking it. i then turn it clockwise to the original position, again it turned easily but about 1 turn clockwise, it gets stuck again.

by the way, i'm turning with only 3 cylinders coz i blew the #4 coz of detonation.

 

If you're turning it on the compression stroke with the plugs in it, then it will be hard to turn. If you try hard enough, it will spin both ways..

You blew number 4? Is there internal damage do you know? Maybe there's something blocking it..

 

cylinders 1-3 seems ok from underneath(oil pan removed) but #4 piston/rods was shattered. i took all the bits and pieces out before turning it, i didn't take off the plugs maybe that explains why it's hard to turn at some point. anyway, thanks guys.

 

that would explain the force needed. sorry bout that
