please help me figure this problem out pleaes

well i decided to replace my stretch timing chain... everything went in as it should and i have the new one on thinking its gonna get this annoying knock away but although it has quiet down, i still hear this loud knock...

this isnt my vid but it sounds like this... only when i rev do i hear it and it goes away after it revs higher if i remember right... is this a rod knock??? hope not

that is rod knock

Just to be sure ill take a vid tomorrow for u guys.... How would i go on fixing this or can i drive like this???

if its rod knock you need a new engine lol. if you plan on attempting to rebuild that one with the rod knock then stop driving it ASAP you will damage the crank pretty bad if you dont.

Dam... Now i dont know what i want to do with it... I really want a 240sx but i dont want to be dumping tons of money into it....

just swap motor for a daily motor worst u will spend is 400 but thats not bad considering a repair will take u well into the1200.

yeah people cant give ka24's away man dont sweat it

if you dont want to deal with it ill buy the car off you if its in decent shape

Wait, so you heard that noise and thought changing the timing chain would make it go away?

Or did I read it wrong?

No i replaced the timing chain because the top chain was stretched... The car is in decent shape... Look at my build... U can see some pictures of it in there

is it the red one on them sexy ass wheels you should trade me LOL
if thats the case dont you dare sale it dame it.

Lol yeah... Its not all red anymore... The only thing red now is the hood, bumpers and pass door... Lol i am willing to look at trades

give you scrap price for the shell

I cant.... I would but i need a car too... Ill sell the whole car for $1500 So that way i can buy a dd... The rails, rocker and strut towers are clean... I just spend $200 do buy the stuff i needed to to do the work i just finished...

ok well i took a vid but it kinda sucks because its from my phone... it does knock kinda loud but it also kinda sounds like a valve tick or something like that...

That almost sounds like timing chain rattle, it does not sounds like it is rythmic like a rod it is hard to tell with the audio in that video.

ii agree, the rod knock is usually quite hard/noticable. and increases with rpm.

that makes me feel much better but what does it sound like to u guys... Ill try to get a better vid

If u look at the vid, the tick or knock sounds like its coming from under the first 2 runners on the intake mani on the left

kind of an old school trick, get the car running, and rev the car up to where you can hear the sound clearly then stick something in the throttle bracket to keep the car at that rpm. then put a screwdriver up to your ear then the metal end down on the motor, move it around and see where you can hear it coming from louder, that usually can help guide you into a more direct area.

Did you change both chains and guides?

Thanks ill do it after work or wen i get a chance.... No i only changed the top...

from the video you posted it didnt sound much of a rod knock. Do you still have the upper chain guide? Try to get a better video.

Well since you only did the top chain and it was streched that bad I would suggest that you replace the lower chain and guides as well

Ill try to get a better vid and i removed both the top guides
