NO, I KNEW WHAT THE PROBLEM WAS. THE EXHAUST SENSOR WAS UNPLUGGED. I JUST DIDN'T RESET THE LIGHT AFTER I PULGGED IT BACK IN

 

Sounds like a thrown rod Bad UMMKAY!!! do not drive it anymore


Seriously bro flat bed that badboy to reputable shop like before NOW!!!!!

AND yes buy a new motor or bore and sleeve that one and go with a a stroker kit or something


you gonna have to spend some cabbage to fix that noise

And stop yelling

 

so you are saying this will cost me $3000+ ???

what could have caused this??

 

 

YUK, sounds close to the same mine did but mine wasnt near as loud. You have thrown a bearing most likely. I did the same thing in my last motor from hard G's in Drifting. Usually oil starvation is the cause. First off you need to tear down the entire bottom end( Short Block) then you need to check to see if any damage has been done to the bottom half of the block.If its damaged its over the with the block. Also you wana check the crank shaft. I replaced mine because I dont like to use a crank that has any sort of damage or imperfections to it. You cannot reuse a bad crank as there is no bearing set for it. What I would do at this poiunt is figure out where you wana be with the car or what you are going to do. If its just a fun car that you have to drive everyday and like playing with it but dont have any plans on building the motor, then put a used motor in or make sure things are ok to do a stock rebuild on , but even then i rather resleeve the motor and make sure everything is par. A motor with such tight tollerances needs to be slapped back together. Sorry to hear about this man, let me know if I can be of help.

 

nasty rod.... Be ready for $$$$

 

You said you had no oil in the motor at at one point. It only takes a few seconds, if that, with no oil to destroy the motor. The problem may not surface right away either.

Sounds like a spun bearing, or a scored cyl will make the same noise. You need an engine.

If you plugged the 02 sensor back in, the CEL would have turned itself off with out resetting. You had a code that probably would have saved you, should you have cleared the ECU and not masked the existing code. Scan it, pull the codes, and look for an engine.

 

i had a thrown rod and a few other things. your motor is foo-barred. Getcha a new one bub.
EDIT: BTW, brand new motor for our car from honda= 9K. Find a good used one for 3K or so.

 

depending on the damage to the scored cylinder you may be able to bore it out, sleeve it (darton makes sleeves for the F20) close the deck and buid it up again for an FI applications or stroked NA. That is what I have heard discussed when others around the shop have come in with scored 4's (#4 cylinder notoriously starved of oil in built F20's).

Either way you are looking at serious negative cash flow on this one.

 

that noise is from lack or no oil in the motor......was the oil light on as well? and when was the last time you checked the oil although its far beon repair now. goodluck
