Help finding a boost leak

Thanks for your input. The Matt Damond one has a check valve standard. The JBR has it as an added cost option. The MD is under $200.

The cheap one on eBay is the older model Corksport. But at $120AU for the can only I don't think it is cheap enough.


Both MD and JBR do hose kits the right length for the CX7 with their catch cans. I almost ordered the MD OCC yesterday but ordered an Aussie made check valve from an OzMPS forum member instead. This should help me solve the immediate check valve problem this week as I will be waiting about 3 weeks for shipping after I order the catch can.


I think I have figured out my BPV problem. I don't think the Cobb has a problem. I used a scale to test it and it is taking about 8psi pressure differential to move the piston and 18psi to open it fully.

So the fact that I was generating the 8psi pressure differential at around 12psi boost pressure indicates I might have a leak from the vacuum/boost hose connection from the manifold to the BPV.

So the plan is to get the improved check valve tomorrow hopefully and pull the intake manifold and replace the check valve and check the BPV hose connection.
