Pressure caps for finding boost leak (SAAB 9-3 2.8 V6)

thingiverse

USE AT OWN RISK! I only needed to go up to about 10psi before the pressure was gone because of the leak. m6x1.0 thread in a schrader valve (thread designed in one of the plugs), pressurise the boost pipes (and intake pipes because I'm lazy), and leak found in moments! To design your own, get a bit of string to wrap around the mounting flanges to mark up (this will give you the circumference, measure the string and divide by pi to give you the diameter) add on material for the fasteners to tighten down on. If you have a valve with a thread (or not like me and had to cut a thread on the valve) design one cap with the same thread and screw it in. PETG as that's all I have left. 4 perimeters, 5 layers top and bottom with only 10 percent gyroid infill
