Boost leak test help

[DROPthatCLUTCH]

Hey guys.
I tested a while back, and found that I was loosing boost from my shaft seals.
Replaced them today.

Now I'm only getting up to like 8 psi and i hear air coming from the valve cover? 'Specially when i take the oil cap off.

Is it just an intake valve open? Or is there something that I'm not doing right?

Tester to turbo inlet, IC pipes all tight.

Do I need to hold a constant supply of air to it?

You can still use the PCV just get an inline check valve like this to use in conjunction with the PCV 3/8" Kynar® Standard Check Valves | U.S. Plastic Corp.

Also, you need to test any PCV you buy by blowing into it. If you can blow through it, it's no good. I've even gone through 4 OEM valves before finding one that sealed. I now use the valve listed above also with my PCV so no more worries of it leaking now.

Also, you need to test any PCV you buy by blowing into it. If you can blow through it in both directions, it's no good.

Fixed.

What was wrong? Why was your valve cover leaking?
