Default IS my engine really gone?

My engine won't start again. Distributor, ECU, fuel pump, relays and all sensors have been replaced two month ago. Battery is brand new. Can crank but just cant start. Been spending thousand on all replacment. I took very good care of my 92 civic esi. I cant feel my engine is dying.

Now the workshop told me that my engine is gone. I wonder if they are telling the truth. This morning, they removed my top engine.

See pictures:




Deep socket is used to crank it, but struck at position. Wont turn anymore even with force.


The first and fourth piston is out by 2-3mm in height. Second and third piston is levelled. IS THIS NORMAL?



I would like to know if my engine is really gone. Is that the reason why my car wont start at times. I would like to know if the shaft can crank freely if normal.

Any corncerns, PM me. I appreciate all helps.

the 3 mm drop is probably caused by a broken rod.....my guess is that is what has the crank stuck in place....only one way to find out...and before payin anyone ese, i would drop the oil pan and check it for myself!!

well if there really is a broken rod then you can either get new rods and install them or do an engine swap. me i would do a swap and use the old engine as a "tinker" engine to play with and rebuild, but thats just me.

as a general rule...if you cant afford down time of a few weeks to a month...your best bet is a swap. that will only run you around 500-700 bux to completion and if you are any good with cars, only take you a matter of days to get done. this will also leave you with an engine to rebuild and modify at your lesiure....
if down time is not an issue, and funding is adequate, pull the motor, get some rods, bearings, seals, rings and do a complete rebuild on the motor. if you're going to rebuild, dont cheap out tho, adn if you intend to modify in the future, now would be a good time to start with sturdy internal parts.
make your decision, and let us know. either way we can help you here on the forums with just about anything, just ask!

and to answer one of your first question, yes the crank should turn freely

I dropped the oil pan and removed all the piston. The no.1 connecting rod is slightly bent. All bearings are good.

Why will this happen?

i was gonna say check the crank position sensor, until you said you cant turn the motor, even with force. i would say just go ahead and swap it out. a stock replacement wont be that much

bent rods occur quite often in motors that are driven hard, or that aren't maintained properly with oil changes. i would suggest a replacement motor. to replace rods, rings, bearings, and seals will cost you just as much as the swap and be much more work ( and labor charges if you cannot do it yourself) for 3-500 bux you can swap, and keep the old motor to build at your leisure. just my 2 cents though.
