why is it tapping or knocking?
i knew my car had an exhuast leak but now there is another noise....it sounds like a loud tapping....it isn't always there but in higher rpms or sometime idle it is there....it comes and goes...at first i thought i threw a rod....then maybe it was my lifters which i think it might be but i'm not too sure...i don't wanna replace one thing and then it end up being something else....so any ideas? or comments? if i can't get any answers i'm not taking any risks and replaceing the engine before i waste more money and blow the dam thing.

Jacked the engine up lately, sorta like a bent oil pan?
Get yourself one of those automotive stethoscope things and pinpoint the noise.
