Re: Need help 1999 honda civic si
Sounds like a trashed engine from where I sit (crappy laptop).
Did it run out of oil? Run too hard while very low on oil?

Hint:
The price of that tax: You get to buy another engine.

Sure you can rebuild it....if you know how.
However, a used engine is normally the more economical approach.
I guess the cost of that will be a big part of the decision.
Estimate each option and see what you think is better.

Re: Need help 1999 honda civic si
You wiped out one or more rod bearings.
To figure out which one is most likely:
Start it up, get it knocking.
Disable each cylinder one at a time, listen for which makes the biggest difference in the amount of knocking noise. Might be tough to tell much of a difference though, so listen carefully.
Once you think you know which one made the most difference....
Remove the oil pan
you will see a crapton of bearing material in the bottom of the pan, and caught in the oil pickup screen.
See which rod end has play. Probably will be a different color too, darkened much more than the rest.
Pull that rod cap off.
Say "DAMN".
Remove the engine. Go to work.
Send it to a real machine shop, the crankshaft will need ground, the rod that spun the bearing will need replaced, etc. Let the machine shop supply the bearings to match their work.
Don't forget to completely disassemble the block and head and clean them. Once a lower bearing is gone, debris can be circulated all throughout the entire oiling system, block, head, cams, rockers, etc.
The stuff can hide in the smallest of corners.....waiting to cause $evere headache$ later on..

How low was the oil? 3 quarts low? 4 quarts?

Re: Need help 1999 honda civic si
Listened to the video again, that sounds like a bearing insert is almost completely missing from the cap of the connecting rod...This extra clearance allows the piston to actually contact the cylinder head when it comes up. Horrible sound.
BTW, what engine is in that?
How old was the oil then?
Combination of low and old?
Nevermind....Doesn't really matter now anyway.
No matter what, it still chucked a bearing.
I'd still do this to figure out which one(s) is the most likely culprit:
Disabling a cylinder is normally done by lifting up the plug wire far enough so that spark plug doesn't fire.

Re: Need help 1999 honda civic si
its a b16a2
the oil was recently changed
the noise sounds like its coming from the cylinder furthest away from the left which i believe is the first cylinder

Re: Need help 1999 honda civic si

#1 is the cylinder closest to the pulley and belts. (The left side of the car.)
#4 is closest to the flywheel/transmission.
Just so ya know.
Anyway,
the noise sounds like its coming from the cylinder
Once you think you know which one it is, then you can pull the pan off and verify/prove what you thought.

Re: Need help 1999 honda civic si
Check all of the cylinders that same way, not just the one. Gotta have some comparison, gotta see how each one affects the knocking.
The knock will get a little bit quieter just from the engine slowing down when each wire is pulled off, so be aware of that-- and that doesn't count.
Listen for a change in the intensity of the knocking.

Ok then....
Next step might be to decide if you should pull the oil pan off, inspect for discoloration of the rods, then remove the rod caps and inspect the bearings.... to verify that you (and me) are correct.
Or just yank the engine out since it is going to come out anyway. Take it apart on the bench instead.

Re: Need help 1999 honda civic si
If you want to SLIDE a bearing shell in and hope, you can try anything you want.
(IMO, waste of time and money)
To do it right you will pull the engine.
The crank will need to be machined, and the rod that had the bearing spin will most likely need replaced. The machine shop can measure the rod and confirm that.
PLUS everything needs to be completely taken apart and cleaned to get all of the bearing debris out. Probably another job for the machine shop?
BTDT. I have to stand behind my work. No shortcuts on this for me. I can't afford to do it again for free.
Always faster and usually cheaper to just chuck a used engine in and drive it.
