DO A LEAK DOWN TEST!!!
INTAKE PRESSURE LEAK TEST

just did mine today and found a huge leak where the UICP meets the hosing for SMIC. tightened and refitted that biatch and she's happy boosting pulling harder than ever.

so do it!

i never did the test on my old 1g, but i did go through and tighten everything one day and i really noticed a big difference....do it

DSM is a breeze 2 hoses I can't understand how someone can miss a cracked pipe or lose clamp, all easly accesible too.


BTW: It's not a leak down test but a pressure test

Try look for a boost leak on a Supra, frikkin nightmare

Glad you fixed yours

Having VFAQ's is one of the benifits of owning a DSM. Searching is another. Learn to use both of them.

These cover pressure testing your intake.

A leak down test is where you pressurize a cylinder via the spark plug hole and measure the difference between the input pressure and the pressure in the cylinder. The difference is the leakage past your rings and valves.
