1G I built a exhaust leak tester

I read online of some one doing something similar.
I went to home Depot, got a plumbing 4" rubber cap it was like 4.99.
The 4" was closer to 4.5 inside diameter.
It fit my SRS exhaust tip perfect.
I took an old PCV valve drilled a hole in the cap and bolted it into the rubber cap.
Then I took apart a old tire valve stem.
Then used a piece of hose to connect the valve stem to the PCV valve nipple.
Total cost 5 bucks and old parts laying around.
Sprayed soapy water on suspect areas.
Worked great found out my O2 housing bolts had worked loose and started leaking, also found a crack in my exhaust manifold. Yay!

Cool. just as an FYI they have bolt on valve stems: https://www.napaonline.com/en/p/NTH90416

also FYI the "correct" (aka $$$$) way of testing for exhaust leaks is with a smoke machine like this: https://www.vehicleservicepros.com/...6/the-benefits-of-highpressure-leak-detectors

Granted I've owned a few 1g DSMs over the years and phantom knock is an insane PITA so I feel ya on doing it this way.

Yea a bolt on tire stem would work even better!
But I didn't have one of those laying around.
