Leak testing exhausts off a car
#22
Maybe a pair of hose clamps, and a tire inner tube?
I was going to try this, with a wheelbarrow tube. Probably just center the valve on one end, and cap the other end with cut up tube. I was even considering sandwiching it between a V-band where I could. Same for my IC plumbing, since I'm doing it in steel now too.
I suck at welding, but it looks like my method of cranking up the heat and wire speed and making a bunch of small hot, stacked spots is working. Looks to be getting pretty deep, doesn't even look that terrible.

Surprised no one mentioned the condom method. Am I the only one who heard of this?
Anyway, you take a condom, and place it over the end of the tailpipe. Using your hand and an air nozzle, you cup your hand over the open (manifold) end, and try to inflate the condom. If you can't blow it off in one quick burst, you have leaks large enough to have to fix.

this is how i do leak down tests on my 2 strokes
these are $12 at home depot racing(natural gas line leak down test guage). schrader on one end, female 3/4" NPT on the other. buy a 3/4" NPT to "size of your choice" reducer, and attach with a silicone coupling or whatever.
then plug the other end with one of these (if you can find one big enough for the piping diameter you are using)
