NEED HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[J.G]

I recently did a tune up to my 01 bonne. ( spark plugs , wires, air filter, fuel filter, oil change and also pcv valve ) I discovered that if I start the engine and I pull the dipstick or remove the oil cap there is a REALLY high vacuum present (if I cover the oil cap opening with my hand there's a huge amount of suction). You can also hear (howling) noises in the manifold. The engine almost dies but just keeps on going .BUT if I re-install the old dirty pcv valve the car would go back to normal.... at first i was thinking about a faulty pcv valve but i try ( 3 ) new pcv but same problem .

Is there a spring and/or an o-ring?

Also, this shouldn't be in Performance and Brainstorming...

yes.. it does have spring and a o-ring...

Did you put the spring & o-ring on the new PCV valve?

I was running into this same issue. My car would actually have a slight blue cloud when initially started. I ended up purchasing a complete PCV rebuild kit (came with all gaskets and the spring) for like $20.00 from a parts store and this corrected my issue. I wasn't able to locate the kit from a Napa or Autozone, ended up finding mine at Advanced Auto I believe.

Below the valve is a plastic piece, pull that out and make sure it's not gunked up or busted, and facing the correct way. The closed part should be towards the bottom.
