okey so today i did a leak down test and they all tested out at around 85%. Im thinking thats ok since I did it with the engine cold.

When i did the boost leak test found a few tiny leaks but what caught my attention was that a lot air was leaking in to the valve cover.

Any suggestions on what that might be thats allowing the air to go to the valve cover.
