I busted a balancer shaft bearing in my Prelude. The bearing is right next to the #3 cylinder. When it broke, it took the tip of the oil squirter with it and closed it shut. I have pulled the crank to replace the balancer shaft metal. I inspected the cylinders by pulling the pistons up and down the cylinder by the rods. All the of the pistons are moving up and down smoothly, but the #3 piston is very hard to move and it makes a sucking sound when I try to move it. In fact, I can't puish it all the way towards the head and it springs back when I try. From the bottom of the piston, I don't see any scarring on the cylinder wall. Could I have messed something up or maybe it's like that from the lack of lubricant after the oil squirter broke and just needs some oil? What could be wrong?

 

Sounds like you're trying to push the piston up w/ the combustion chamber still sealed.....

My friend said something about trying to push the piston in while the valve stem was down. Is that along the lines of what you are saying?

 

Yup; I should have elaborated more.

Is the head off?

If not, pull out the spark plugs so that the air can move out of the cylinders when you push the piston up.

 

Yup. That worked. Thanks
