I have had quite a few problems with my crx, the most concerning .. i thought was an issue with the tranny.. but when I rev to 7krpm exactly, it will scratch and rpms drop and continue to scratch until you let off or change gears.. it doesnt happen everytime, it has happened 4 times in the last 2 weeks about 50% of the time..

so I reved it up in neutral and it did the same thing... it sounds mechanical but can it be something electrical? since it is at a specific RPM?

this is a first gen b16 with an unknown amount of miles.. doesnt leak/burn any fluids.. doesnt run as fast as it should.. something is just not right with ..


Any ideas as to what this could be? anyone have had the same problem?

 

no one at all?

 

Changed the oil? Could be a bad bearing as well.

 

yeah, i just changed the oil yesterday, the oil that was in there wasnt bad at all..
i havnt tried to take it up to 7k since then.. its shady.. bad bearing? any other possibilities..

might jus tsay expletive it and bring it to JE when i get my tax return

 

Hmmm.. I get a rattling, shaking/scratching sound at 3900rpm whenever I'm cruzing. I can drive right through it and it will just make a quick sound, or I can hold it right on that rev range and I just drive around making that noise.

I wondered what it was too, I thought it might be similiar, but it doesn't seem like it is.

Sorry.

 

it is a scary grind, like .. an oh **** oh **** and take it out of gear as fast as possible grind..

 

I know my cat rattles at about 3k rpm, may want to check to see if its a vibration.

 

my cat or heatsheild vibrates around 2.5k-3k , but its not that.. the car actually stops pulling and rpms drop loud scratching noise is the best way to describe it. i tried searching for this but could not find anything.. such a strange problem.. no one has had this happen?

 

anyone?? please help!

 

i would guess gear that your in when your at 3k, or a bearing in the engine maybe a piston could a piston be kinds warped or a cylinder be warped and not make much njoise till that high an rpm? dont know, just tossing ideas out there

 

no noise from the engine until its at exactly 7k,.. then it makes a scary grind/scratch and loses power it does not do it everytime either.. but when it does not do it .. it does not pull like it should after 7k , vtec engages good, you can hear and feel it..
it does need a tune.. there is an aftermarket fuel rail on there and no FPR.. the guy i bought it from was not too bright..

i get around 30mpg and doesnt burn/leak anything.. really scratching my head here..

could be a spun bearing.. you need a fpr though.. something internal is def grinding.. tear the block apart and find out..

 

Just a suggestion, get a friend to hold the rev's at 7k, you listen for the noise, I'm just guessing with your lack of power and grinding noise you may have a dist. bearing going. Pull the diz cap and check for red dust.
