Hope someone can help me here..
I bought a boost leak tester recently and have just finished trying to test the system on my X reg 1.8VT Seat Leon, i connected the tester to the TIP pipe and plugged the oil breather and took my oil cap off, but what psi should i be putting through the system?
I put in 8psi using my tyre inflator but the needle on the boost tester did not move and i could not hear any escaping air, do i need to go much higher to properly test or am i doing something wrong.
