D16A6 help
 

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? >:(

Re:D16A6 help
 

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?

Re:D16A6 help
 

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?

Re:D16A6 help
 

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.

Re:D16A6 help
 

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

Re:D16A6 help
 

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

Re:D16A6 help
 

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

Re:D16A6 help
 

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

Re:D16A6 help
 

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!

Re:D16A6 help
 

could be frozen up on the inside too.?

Re:D16A6 help
 

You think so? Hmmmm, maybe ill let my heaters run all day and warm up the block and see if that works before ripping everything apart.

Re:D16A6 help
 

ya.. like.. if its THAT cold, theres no oil (to repel moisture), think of how your tounge sticks to a metal post in the winter.. same deal going on maybe?

got a block heater?

Re:D16A6 help
 

No, ill stick a space heater right next to the block though, give my garage like 4-5 hours to warm up. Thanks man i didn't even think about that.

Re:D16A6 help
 

I am assuming it is frozen. I would pull the oil pan and use a heat gun or hair dryer to thaw out the cylinders and then spray some wd-40 on the cylinder walls and down the spark plug holes in the head. Then with some lube on the cylinder walls try to turn the crank pulley.

Re:D16A6 help
 

Thanks ill give it a shot this sunday on my day off from work, suppose to warm up too.

Re:D16A6 help
 

i say if u get it started (with oil duh), do a back to back oil change to flush the moisture.

Re:D16A6 help
 

I heated the block up today to about 100 degrees, put a shitload of wd-40 in the cyclinders let it sit for an hour then put more wd-40 in, unloosened the crankshaft bolt and tightened it back on and continued to tighten and the bolt snaps and it now stuck in the crankshaft. >:(

Re:D16A6 help
 

You aren't having much luck, are you? Now that ------- sucks. Why didn't you put any oil in the motor after you were done with the engine? ??? Have you pulled the oil pan to check things out or to lube the cylinders walls? Now is the time to stop dicking around and figure this out before you break something else.

Re:D16A6 help
 

Extracting bolts in hard to reach places absolutely sucks the mother of all lefties on a hot day

Kinda odd for a known good motor to just freeze up though, shoulda had some oil there there though

good luck to ya
