Default A few breather questions again

I have the new intake on my Astra it sounds sweet, I had to disconnect the pipe that actually draws the air into the crankcase via the rocker cover and put a lil'filter on it so that it doesn't draw in any grit if any which went well.

Now there is a problem with it, I was checking for movement on the filter pipes when suddenly I got a blast of noxious fumes in the face, I know that the oil gets hot when running through the block but to exit out of a pipe that is continuously sucking in air to keep PCV.

Is there anything I could do to stop the smell?

I have outlined all 3 breater pipes in the attachment

I don't really understand your question, but I noticed that all you did was put a filter on the PCV (the bottom hose in the pic). What many people do is install a catch can that collect oil and stuff that get suck into the PCV before going through the filter.

Maybe you could find a inline filter of sorts to trap the oil and also send the fumes into the intake. I have never had any weird fumes come out of my car when I had a filter on my PCV. I just decided with my new engine that i would leave it in place.

Well I cant find any 22mm pipe that is worth getting, to connect the rocker cover to the intake extrusion which I have blocked off. Also you can feel the air getting sucked into the rocker if you cup the filter.

No oil is actually getting out, its just a wierd smell I noticed and wondered if I would manage to get into the cabin if the vents were on

I think if you don't like the smell you should put the breather tube back into the intake stream. Or maybe you could make some sort of charcoal filter. I just don't think it will be that easy.

Ok this is probably the last question but I really didn't think about it till now

I have the breather filter on the PCV and when the hot lump is turned off it will let out any vapours since the throttle isn't creating a vacuum and pulling in cool air into the crankcase

OK so while it does this every day, will the oil dry up and go crusty under the rocker cover?

No, it's not gonna dry out. IF it does, it's not motor oil.

I would just route the pcv to another vacuum port and take that filter off all together besides your just letting those fumes into the atmosphere they need to cycle back to the motor. that's the smell of carbon gas and oil mixing.
