I did some searching on here about leakdown tests, and found plenty of places it is mentioned, but no info on what exactly it is, what I need to do it, or how to do it.
Could somebody maybe help me out with this, or point me in the right direction?

Basically what it is is checking for vacuum leaks from top to bottom.

Intake, TB, manifold, EGR, other hoses
valve cover, head, PCV
piston rings
exhaust manifold,

I think that's it.

As far as the top end goes, if the idle is off then check the seals for the hoses and the bolts for the EGR.

4g63attack knows more about it.

Het Turd, thanks man. That gives me a really good idea of what it is now. Honestly, it sounds like a pain in the a$s to do, but also, well worth it as well.
I think I may have that done in the near futue.
Thanks again!

Thanks Attack. I can see where it would come in handy, trying to make sure all of the seals were perfect. :57:
