Thread: How To Make a Boost Leak Tester

Can the car be off

You have to test it with the car off

so how exactly do I use this?

Helpful tool put a air pressure gauge on as well,. I just used a fuel line with male fuel fitting and air valve with the valve on inside removed. I would post pic but I can't manage to attach photos

Just hook up the tire inflator from the compressor and start adding air and listen

thanks man appericate that!

I went to my local lowes looking for a PVC End Cap and all of the workers looked at me as if I was speaking greek!

Where else could I go to find the PVC end cap?

Just look with the plumbing and PVC piping pieces? They should have them, my local LOWES does? You could also try Home Depot or I'm sure any store that carries Plumbing type things.

The caps I did find, where rounded at the end and weren't flat!

do you not need to close off the end by the TB? i would think that the pressure would go into the engine & then start pressurizing it (not sure if thats bad or not)

I just always assumed that you would use one of these on sections of the IC at a time..

IE.

connect to the hot IC pipe & block off the end before the IC....check....no leaks, then include with the IC but block off the "cold" end of the IC, works, then move to the end right before the TB

disconnect from the TB, & block off that end & test.
