exhaust leak and sea foam

I have an exhaust leak and have decided to use the vacuum line and sea foam method to find it. The only problem being I have no idea how much to use or which line to use... I have an '02 GT

I'm not a fan of Seafoam.
How do you find an exhaust leak with it?
Without getting underneath the car...

That seems like the hard way to me. You have to get under the car to fix it anyway.
Just my opinion.
Good luck with whatever method you choose!

If you want you can stop by my work and we can put it on a lift at some point to look for it.

Haha I can show em what a real car looks like

I just had a thought about all this though, if I'm planning on upgrading my exhaust, is it worth the effort to fix the leak now? Or can that be fixed when I change the exhaust?

Depends on what's leaking. If it's an easy I would go ahead ad get it fixed

I've never heard of someone using seafoam to check for an exhaust leak before, although I see what you're saying. I don't think it would help much, but if your gonna use it for a vacuum leak, the best place to "pour it in" (the vacuum will actually suck it up as long as you don't dump a ton in at once) is at the pcv valve on the passenger side valve cover.

Could you possibly post a picture of it? I don't know where everything is in my engine, new to this whole scene

I would, but I'm not at home to be able to. A quick google search provided this image though:

Its the black thing that's plug into the passenger side valve cover. Can't miss it. If you take it out while youe car is running, you'll hear your car idle funny. Put your finger on the end and you'll feel it sucking in air.

How the heck is that the hard way?
Obviously sea foam creates white smoke .. All you have to do is look for smoke coming out from a exhaust pipe..

I can't see the exhaust system, well enough, when the car is sitting on the ground and I would just jack it up, find the leak, then fix it. All in one shot.

Call me crazy...
