    No takers?

    No one w/a FSM?

    Want to do a quick check to make sure there are no leaks...

    I am of course assuming that the same principles apply and I will be able to detect an exhaust leak with a vacuum gage on a 100...

    Work with me here. How do you find out if there is an exhaust leak by measuring the vacuum?

    I've got an FSM but not with me right now. I can look Thurs or Fri if need be.

    Calamaridog,

    No problem....I believe that the basis for detecting a leak w/a vacuum gage is this:

    If there is no leak, the gage should hold steady at n/in mq(inches of mercury) at idle...if there is a leak, then the gauge will jump.

    Got it, good tech article.

    I'll check the FSM when I have a chance and see what it says about the exhaust system.

    I haven't gone there yet as I'm paranoid I might have a cracked exhaust manifold, like so many others.

    FSM doesn't say anything about leaks from exhaust manifold, as far as I can tell. I found a diagram having to do with vacuum lines but my scanner is on the s***ter. When I get the new one plugged in, I'll post the diagram here.

    PCV valve is a possible location for vacuum. Used the PCV for introducing SEAFOAM to the 3.4 on the Taco.
