somebodys gotta know what this noise is

[My95Z]

Its hard to hear, but I'd double check your rockers b/f you declare a dead lifter (its easier to fix!) but if it keeps happening it might be the lifter.

Do you have poly locks on?

[Spartan7]

What rockers are you running? My Pro Mags kind of sound like that, like a sewing machine. Did the sound just start recently?

[Adam]

It's hard to hear, try taking a video and moving the camera around and back up a few feet and then come in close.

[devonsZ28]

dont know if there are poly locks, all i know is there comp 1.6s put on by the previous owner, ill go take another video real quick

edit: yes it just started a couple days ago as soon as i started the car

[devonsZ28]

new video = fail, there was to much wind ill try again later

[ThreeHonks]

Do NOT just try and tighten the rockers. This could cause you to bottom out on one of the lifters and make it even worse. Just reset everything back to 1/2 past 0 lash or so

^my dad explained to me how to do it, but im gonna have to have him explain it again before i do it

Edit: well doesnt look like ill be doin any work today, since its f##king snowing

[devonsZ28]

well i adjusted the rockers today and it didnt help, FML
oh but the service engine soon light decided to come on

[Fastbird]

What code is is throwing?

[devonsZ28]

not sure what code or even how to tell, but i did realize that the front of the motor is leaking oil im not 100% sure yet but i think its from the intake

[StangeatinZ28]

sounds like a bad lifter or a bent pushrod. my guess was going to be to set the lash but apparently it didn't work

[devonsZ28]

it didnt look like any of the pushrods were bent but iv never seen a bent pushrod so i dont know how noticable it is, i have tommoro off so might adjust them again, guess it couldnt hurt

[StangeatinZ28]

it didnt look like any of the pushrods were bent but iv never seen a bent pushrod so i dont know how noticable it is, i have tommoro off so might adjust them again, guess it couldnt hurttake em out and roll them on a flat table. if they wabble they are bent lol

[devonsZ28]

what could cause them to bend?

[StangeatinZ28]

what could cause them to bend?loose valve train, or over revving, or a stuck lifter

[devonsZ28]

well it turned out to be a bent pushrod, thank for the help guys

[JAKEJR]

Pushrods don't usually JUST BEND. There's probably an interference problem somewhere in the valve train. Find it or this'll probably happen again.
