Message Is this supposed to happen. I found many leaks and fixed them. I went to bottom of the car and found air coming around the gasket between the down pipe and test pipe. The bolt was a little loose for some reason. Tightened up all that. Someone did a crappy job on the welds of the test pipe cus I found a pin hole. I have about 4.5lbs on the intake right now. I know there are valves open a certain points of rotation obviously, so is this where the the airs getting to the pipes I hope. From what I've research the intake is supposed to hold pressure. I also can move the HKS Bov's around a bit and they leak out the o-ring. I knew that was a crappy setup when I seen it at first. Please help me shed some light on this fellas.
