OK, so there was a loud knocking noise, and I didnt think much of it. A few hours later, I started my SOL up and started driving. The motor began to stall, and then didnt start back up. When I tried to pop start it- the motor didnt turn over. It cranks, just the 1st cylinder is all locked up. I took off my valve cover- my valves are fine. I took out the spark plugs, and stuck a long wire down there, and put it on top of the piston- and cranked the motor. The piston did not move up and down. Im guessing i snapped a rod. I did not throw the rod, because there are no holes anywhere in the block. Is there any way I can fix this without totally taking everything apart?

 

No. You need to take it apart to see exactly what the damage is.

 

what does taking it aprt consist of....Can i just take off the oil pan and see if i see anything?

 

I`d at least pull the head and pan.

thats what I would do....

 

that happend to my last blown engine. Most likely you have the following damage

1. rod broke
2. bad piston
4. piston hit bottom of head (could be valve damage depends on the rpm when it broke)
5. cyl walls scarded and scratched when the rod broke, most likely trashed
6. crank most likely distoryed behond resurfacing

i hate to tell you...its time for a new motor. If the cyl walls are ok or its light enough that you can rebore to fix (but then you would need all new pistons) you are still going to need a new crank and then a complete engine rebuild.

drop the oil pan, if your #1 cylinder connecting rod is laying limp, or pieces of it are everywhere, throw your motor in the trash.

 

so wait . . . ur #1 piston doesnt move, but the rest do? ur motor is phucked.

My friend was swapping a B18c into his coupe, and on the way to the garage this happened to him. He spun a rod, so I'm assuming that's what happened to you. In the words of 97civhatch,

 

What does "spun a rod" mean?

 

Blew a piece of it out through the block. Sorry, that may not be the correct terminology. I always mess that **** up.

 

dont be lazy man. sorry to say but it dont sound like a little problem. get a b16 or some other motor.

 

Thats what you get for driving like what you signature says.

 

lol, the thing that sucks is- i havent raced my car for about 6 months prior to this, and when it happened i was in residential going 35....I just have the worlds worst luck...on x-mas eve my car got broken into.....2 days later i got fired from my job....now im back in work- and i stripped down my car- i guess it will be fun redoing everything- just would be better if i had money....but in a few days ill post some pics and gradually post pics throught the project....o0o yea, anyone out there got a sohc motor for sale?

 

same thing happened to my friend's 97 civic. he was just driving normally one day when a rod decided to snap. an all-nighter and $350 later we had the new engine installed. fun ****.

 

The rod to rod bearing to crank clearance gets loose enough that the rod bearing can spin around in the journal. Normally when this happens the rod is slamming up and down on the crank. It only takes a few seconds to distroy the crank and rod.
