I've asked this before and still whondering if anyone can help me i got a 87 v6 2.8L firebird and was just whondering if anyone knew what this noise is its a knockingbanging noise coming from the engine when i hit the gas i checked the oil and everythin its all good anyone know what this could be?
could it be reving my engine to much?

 

Sounds like pinging.

Ignition timing advanced too far, or EGR valve not operating properly.

 

it was fine but then i revd it alot and drove it and then it started makin that noise

 

Need a better description, then, of "knockingbanging noise coming from the engine when i hit the gas".

Rod bearings will tend to knock at any speed. Main bearings you may not hear at idle, but is a very hard knocking noise. Piston wrist pin or skirt slap tends to have a two-toned note to it (knocka-knocka-knocka rather than knock-knock-knock). Loose torque converter may require more RPMs to hear, but can sound like it's coming from the engine. Valve train tends to be more of a tap than knock.

If it started after a period of abuse, most likely you ruined something internal to the engine.
