whats the differents with this one, this is the one i have on my car

ahd this part below

 

i looked around this board and found nothing at all, and i guess no one wantes to help

 

Is it a loud tapping noise like when you back it off the rocker arm nut, or kind of like a sewing machine? Also, do you have flat tappet or roller lifters?

 

flat tappet


it sounds like a tapping noise, at idle i cant hear it , when i press the gas it gets louder, the fast i go m the louder it gets



whats the different with tapping and sewing machine sounds

 

If you back off the rockers they tap loud. Is it the same noise after they're adjusted? Rocker arms shouldn't make noise unless they're fubared. Are you sure it's not an exhaust leak?

 

what do u mean backing off the rockers,


i did think it was an exhaust leak, and my exhaust was leaking, and had the pipes replace, i might be leaking from the headers,

its coming the passenger side it sounds likes the rocker arms. it might be leaking from the headers, the bolts are tight, i will try to replace the gasket and see what happens, i had mechanic adjust the rockers, the rocker are tighten to specs

 

whats fubared mean, and yes the make the same noise after they been adjusted

 

umm, that's how you adjust them.....by backing of the nut with the engine running, tightening it to zero lash (tapping noise goes away), and then going an extra 1/2 to 1 full turn. My question in a nutshell is when you back them off with it running, does it make the same noise that you're hearing or a different one?

fubared= f'd up beyond all recogintion

 

i didnt adjust them, someone else did, but i think they know what they are doing

when u adjust them, with engine running does oil go everywhere

but i cant hear it idle, only when its im pressing the gas

 

Then I would ask whomever adjusted them if it's a valvetrain noise. WAG is it's a header leak. Good luck.
