how to to test pcv valve/hose?

[f4m0u5]

I have a 2001.5 with the nerstyle spider hose/pcv hose.

My car had the vcgs and all associated gaskets/seals/plugs replaced arpund 10k miles ago to clear up my oil leaks. Now i have oil leaking down the front from what i belive is the crankshaft seal.

so im wondering how to check the pcv system to make sure thats notcausing my leak from excessive pressure.


I tried puling oil cap off and car didnt hesitate at all and realized there is no suction in there either. Put a piecs of paper too it and it did not suck it against the valve cover.

Remove spider hose, there is a check valve in the center fitting. Blow and suck through the ends with the valve to test the valve. It should flow one way and not the other.

You should be able to pull vacuum in it but not blow into ir
