Ive been out of the game for some time now. I just picked up a 94 gsr as a beater. Well i believe i spun a rod bearing. Assuming I did, how feasible is it gonna be to just throw some new bearings in? Assuming the crank is fine, Is it possible to do it without removing the engine?

I realize i should plastigage, but i really want this to be as quick as possible, i dont plan to put a ton of miles on this. Is this possible?

Keep in mind this is just gonna be my daily beater


maybe some acl bearings? i hear those arent as precise...compared to honda parts

 

I too am curious if it is possible to do this without pulling the engine.

 

the color codes should be on your block for which bearings you will need. also, it is possible to change them while the engine is still in the car. i can't think of any reason you couldn't. unless the crank does not move enough with the flywheel on. as long as no scar damage has happened from spinning. just buy the oem bearings of the correct color. torque to spec and drive.

post this in the all motor forum and see what they say. it's those upper bearings i wonder about. can you wiggle the crank enough to get them out.

 

would it be on the serial number? how much is honda stuff? compared to acl? i see ebay has some acls for 35+13 shipping..

Acl theoretically covers all colors from honda

 

actually standard acls are equivalent to honda green bearings. i believe the make an oversize acl bearing as well.

 

i am actually in the process of putting new rod bearings into my integra and yes you can do it without removing the engine. just drop the oil pan and go from there.

i've never messed with the inside of my engine before so didnt i know what to expect besides what i've read on here, but getting in there and rolling out the old bearings is cake just be careful.

just got a new set of bearings from autozone, Clevites CB1353P, for about $45.

i too have a knock that just started but only need my car to run for at least another 6 months so i can save for a complete rebuild or swap. i think it should last me at least that.

i'll be putting em in tomorrow! can't wait. i miss driving my car

 

are you gonna change them all out? or just the ones that are bad? is this is anything like the last motor that i had this happen to, it was cylinder 1....i think ill probably do them all. let me know how it goes

Did you go with the oversized? or just the regular?

 

yeah i am gonna change them all out as recommended by my gf's dad (pit crew mechanic). he said if the engine has never been rebuilt yet, then standard size should be fine so i went with standard.

i will definitely let you know how it goes.

 

Take pictures. Your's is a B18B, right?

 

yes, b18b. if brooklynn lets me use the camera with my oily hands, i'll take pics i'll post em in my thread tho so as not to jack integra3586's thread

 

feel free to thread jack

 

this is totally the case with all american v-8s i know of. however, honda uses different colors to get clearances exact. the car will run fine with acl or clevite however, it's likely your clearance will be on the loose side. that might not be super bad if you have a little rash on the crank though. as long as you're not over .0025 you shouldn't have too many issues. that's still above the honda service limit by the way. i don't see why you don't just decode your block and buy the correct oem parts

 

i think i read somewhere on H-T where someone called Honda to get new bearings and Honda told them they were discontinued. i think that was for a d16y8 though. but i was told generic/standard bearings would be ok to last me for a good while. the motor has about 270K miles already so i don't expect it to last much longer.

 

ask yourself how that is possible

 

from what i understand, they are just looser tolerances...i know its no where close to being ideal, i really just want it to run for a while. Now ive read they may make 2 or 3 different sizes

 

they do, but only one if for oem replacement. others are under/ oversize. i just don't understand why you are choosing these over the proper oem part. labor is the same either way.

 

im trying to spend a little as possible. Im only assuming Honda parts will be more money.

also, wouldnt the dimensions of the crank journals change with 227,000 miles? So would the original parts still be the same?

 

Save money and have to do it again or spend a little more and do it right?

 

the way i will be doing this, its not ideal either way. Im not mic-ing the crank, hell im not even gonna pull the motor. I doubt using ACL or Clevites will shorten the life by THAT much

 

you're correct about the crank being a little off with 227k, it's likely there will be some wear. as long as you're not over .0025 it should live awhile provided the surface isn't rough. i think the honda service limit is .0020 but i know of one b18c with .0025 that's going on 30k miles with no issues. i have no idea what the clearance is with clevite but the acl is normally the middle of the honda range. as long as the crank isn't gouged it should work for quite some time. if this fails, it will likely do so within the first 2000 miles.

 

ok, i just pulled the pan, this is what i found

The main Bearings look really bad! Is this where my knock is coming from?



This is the suspected Spun bearing, it was the only one with up and down play. The others had slight side to side, which im not sure is normal or not.



What will happen to the crank if i just leave to old bearings in?

Its not possible to change the main bearings in the car right?

 

man you have rocks in your engine.

Those do not look good. I'm pretty sure that you have to pull the engine to replace the main bearings. Do a B18B swap for cheap, rebuild the B18C1, and either sell it or reswap.

 

yea, im considering selling the vtec head and getting a cheap engine. I was actually contemplating a d series purely for the gas mileage. Ill do some research and see what will be more cost effective. Honestly i would prefer to get this thing running again though

 

yikes those bearings look a little weathered lol..

anyhow i finished me rod bearing job today i'll be posting pics in my thread shortly..

good luck with those mains!!

 

you can change the bearings with it all in the car. i just asked to confirm it. also, the one bad bearing. what's the crank look like there? can you feel anything? if you can't you could re-bearing and run. you literally had crap get in your oil. if the crank is gouged, you have to pull the motor.
