diy leak down tester

[Starwriter]

I like your leak down kit!! Where ya get that??

I made it in the lathe. For the exhaust caps, I use stock Banshee front bumper rubber caps. They fit perfectly.

If you don't mind buying an actual tool a Mity Vac MV8500 is a nice kit to have. Comes with different size plugs for plugging lines. Brake bleeder cup / kit. The pump can do 30 PSI of pressure or 25 InHg vacuum. It has a gauge and is air tight. I just tested a Trevor Simpson 30.5cc motor that I built for my HPI Baja. It held 10 PSI of pressure for 20 min, and 15 InHg for 20 minutes. No leakage at all from the motor or the pump / gauge.

 

Here is the kit I am talking about. You will still need intake and exhaust plugs of some sort.

The mighty vac works great if you want to pull a vacuum through pulse lines. I use them for jet skis.

Shit, that Mitty vac is the answer to your endless front brake bleed sessions
