I posted this as a response on a subaru forum when i found an article that sounded like my issue....
please let me know what you think!!!
DID ANYONE EVER HEAR THE RESULT OF THIS????
I have the exact same sounding issue on my 2001 Honda accord 4 cyl. It quiet until its warmed up, then I have a knock from like 1700-2200 rpms (but only under light acceleration -- more or less maintaining speed when driving).
its been driving me CRAZY as i just bought this car 2 months ago and first heard it on the way home from the dealer (when it was fully warmed up).
It sounds like this guys timing belt did in fact get ripped probably by the tensioner? Does anyone know if my Honda could have the same demise? I was going to change the belt as soon as i got it, but i wasnt sure if this noise is a rod / bearing / wrist pin or something... one mechanics theory was a wrist pin and my other mechanic said he thought the tensioner and honda said its "normal for the miles" (95k mikes) which is crap cause it cant be normal as it is a decently loud knock under a light load when warmed up.... I can get it to do it when in neutral if i rev it a little around that rpm range...
the one mechanic thought it was coming from the T-belt side as he used a long screwdriver to listen.. said he didnt think its from the lower end... but this sure sounds like a deep knock / rattle around those rpms only and there is some vibration in the motor also possibly (more than when cold at least)
It doesnt seem like spark knock at all....
ANy theories? Could this be the same issue? I dont wanna put all the money into the car to have my mechanic rip it apart and change the timing belt and tensioner only to find out that it still makes the noise when all is said and done... but i definitely dont wanna blow the motor over a snapped timing belt if it is the same issue!!!!
