Basically when the car is running, in drive or reverse, and stopped i hear a consistent knock when sitting inside the car (Its quiet enough where the radio must be off to hear it good). If i put my foot on the break and give it a little gas the noise increases speed with the engine speed. The noise is also slightly louder when the car has warmed up. However I cannot hear the knock when i am outside of the car (while its in drive). If its in park and I rev it to the like 3000 rpm i hear a rattling/knock only as the rpm slightly increases or decreases in the 3000 rpm range.

When the car is idle in park whether your inside the car or not warmed up or not. You cannot hear any knocks. The engine runs smooth and i really hope its not a wrist pin or bearing knock.

Here is a video clip of it

The way you describe it, I'd say an engine knock; no idea what an exhaust leak would sound like on one of those motors though.

 

Yeah i know. I mean i paid 400$ from my sister so no biggie if it blows up. But did you listen to the video. Idk its not ridiculously loud. Its just nice to have for the mpgs.

Thanks

Well if it defiantly is an internal knock it's cheaper to just buy another motor than to start replacing things. (after gaskets, bearings, probably have to have the crank cut you are just in it for way more than you should be).

 

More pronounced when the tranny is loaded against the motor? Maybe the flex plate?

 

I'm familiar with a whining noise (similar to strait cut gears, supercharger or a gear driven timing chain) or horrible vibration in that situation?

It's physically still running smooth though?

 

Yeah the car runs great, starts right up, vtec kicks in LOL. I sat my sister in the car and asked her if she has ever heard the noise and how long has it been happening for. Shes was definitely unsure, and said probably like a year, but never listened for it, or thought anything of it really so i got like an iffy answer from her.

It needs two front fenders and a bumper, and the a/c doesnt work. Easy stuff but Idk if I would even drop a motor in it. If the motor were to blow I would it probably part it for a few bucks than junk it. But its a nice car to have and i really would like to keep it but i just cant figure this knock out.

Everyone I talk to is just like Run it til it blows brotha!! but thats not my stlye, I wanna know what the deal is cuz I am not interested in being stranded on the side of the road!

Thanks

Oh and by the way whats pretty funny is that I posed this same post on 3 Different 'Honda' forums and cant get one reply. Same thing when i had my chevy truck on the GM forums, barely can get people to talk. This forum is great. Thanks again

Sounds like an engine knock, it can seize at any time if it's bearing related or it can run for a while.
Your average Honda kid doesn't have a clue what they are talking about; it's mainly them passing on what they've read or heard. Half of them would probably be hard pressed to change their oil.

 

Yeah good point. I think the bottom line is that its a knockin, and time will only tell.

Thanks

Could be a motor mount shaking, or the valves could need adjustment too

 

id run it til something happens hondas r notorius for knocks and wierd noises but they always seem to hold togther its possible could be valve chatter if sounds like a grating metallic sound id say could be bearings in bottom end only way to check is dig in and start unbolting stuff or at least have look at ur oil when u change it and look for any metal shavings i wouldn worry bout it honda motors are dime a dozen and as much as u payed for it ud still be under 1000 fir another motor son
