Ok, im putting my stock D16A6 back into my 91 Civic. Anyways i get the motor in with out the rocker arm assembly on and the pistons moved freely. I put the rocker arm assembly back together and on. I stopped working on it for about a month and put the car outside in the cold and now i can't rotate the motor or the cam shaft, i disconnected the timing belt and tried to rotate the motor and it feels like it's stuck(like i over tightened the rod bolts, which i didn't because i did that before i put the motor in and fixed it.). I was using a 5 foot breaker bar tighting up the crank shaft bolt so much it felt like if tightened it anymore it would snap. So i go to rotate the motor and it just lossens the bolt. I tried using the starter to rotate the motor and it couldn't do it either(I pulled the plugs out too). Ugh i don't know what to do, any suggestions, should i rip the ------- head back off?

 

Did you try rotating the crank clockwise so the bolt doesn't come loose and did you try putting the car in gear and pushing it?

 

Yeah it felt like the bolt was gonna snap if i went anymore. No i haven't tried pushing it, maybe ill give that a try, isn't it really hard to push it in gear?

 

I'm not exactly sure, but I know I was moving my car when I had it in gear trying to tighten the crank pulley bolt. I think you should be able to push it if you have the spark plugs out. If you can't get help.

 

Let me go out and try to push it in gear and ill get back to ya.

 

Ok, i tried all the gears and the crankshaft didn't move, the car moved fine but crankshaft didn't move at all.

 

so even with the timing belt off u cant move the motor either way? the valves are installed,right?

 

I don't get it. You mean your clutch is slipping when you push it?

 

Yeah the vavles are installed right, should be this motor ran fine when i had it in before.

I dunno, i put the tranny in gear pushed it and nothing the car moves fine. Like i said earlier the starter couldn't even rotate the motor.

Acouple other things i remembered, i honned out the cyclinder walls and didn't put oil on the walls when i was done and just installed the pistons. Second is there is no oil in the motor at all and the temps have been ranging here from 60 to -25 so i might have got condensation in the cyclinders and they might have rusted, maybe? I guess i rip off the head and oil pan lossen the rob bolts and see whats up. Damnit!

 

could be frozen up on the inside too.?
