spun rod bearing....
 

well i dont really need help on repairing this.. my dad and his mechanics are gonna get me running again... but my question for you is this....

how can a naturally aspirated, non-nitrous SOHC civic that is well maintained, get a spun bearing?
:eek:

If you had a problem with your oil system, or you beat it up while its cold. I can't think of too many ways.

well if worst comes to shove.. i guess ill have to do a little transplant.. but i usually let me engine warm up to the point where it hovers around 1000rpms before i rag on it..

at any rate.. this is very disturbing for me... but it could also be the reason it was making a slight noise before i changed my clutch months ago, i thought it was a pilot bearing or release bearing in the tranny.. but it went away when i pressed the clutch.. but the noise came back and it sounded like it came from the passenger side.. now it sounds like its coming from the driver side... i would like to rebuild the entire engine.. but i dont have time to fool around with this stuff, its my daily driver... so im gonna see what i can do.. HOPEFULLY i wont have to do too much.. a swap right now would take forever and a day... and i cant afford to have it out of commission too long..

so think i figured out why the bearing went bad.. front motor mount was screwed... would that cause vibration at highway speeds?

shit happens all the time, there is really no explanation, every part fails eventually.

^^^ not really true

well i got another d17 from an em2... thats getting prepped to be dropped in right now.. i wish it was a k20.. but budget and time makes it out of reach for me at the moment

I was in your same position, i just had to replace my motor because of a spun rod bearing. mine gave out because of low engine oil, high reving, plus nitrous= not good! :rtfm: . but its a fairly easy swap, did mine in about day and a half. How much did you end up paying for your new engine?

and what oil have you been using?

i been using amsoil, i paid about 700 for the motor... but it wasnt complete.. i gotta use my old ac compressor ps pump, alternator...

after i get the motor out i gotta put the clutch, harmonic balancer, plugs, and little things on the new one

so your saying that the engine mount caused you to spin a bearing ? how ? you used to get vibration at highway speedS? how fast? my front engine mount was almost dead at 40,000 so i got energy suspension its fine now

well how can you tell if you have a spun rod bearing beacause is just heard a knocking noise when i was on the highway and then i got off to check what it was all i can here was a knock from the head thinking it was my valves next day i took the head of and the head seems to be fine

If you spun a bearing youll hear it during idle. Youll notice a loss in power due to loss of compression to the piston with the bad bearing. Youll know when a rod bearing gives!

ok cause i did felt of loss in power but i dont hear it at idle i hear it when the rpm hit 2k+ and thought it was my valves bent but were fine how much would it cost to fix and i was on this web site that have a rebuilding kit for 541.64 +s&h is it worth it

well today i just took the block out i had already took the head cause i thought it was my valvesand it wasn't but i took the oil pan off and checked the rod bearing and sure enough it was it was eatin up pretty bad but i going to buy another motor and keep and rebuild it with internals to boost the hell out of it
