so im just finishing up the plans for my emmissions removal, this is where I need help.

Im looking for the simplest way to remove the whole system. Can I simply run the line from the oil filler tube to vacuum or to atmosphere? is that all thats NECESSARY?
will this allow me to eliminate the purge valve and everything?


and just to combine another Q.. do the fuel injector breather lines just need to go to vacuum anywhere? Is there only one breather line for the primary rail? (the lone vacuum nipple in the direction of the exhuaust ports)

You can run the line from the filler to atmosphere or a catchcan. The injector air bleeds need to go to a fresh air source.

what if I attatch a vacuum line and tie it vertically to the filler neck. that'll alow it to breath, but no oil will drip out.



by fresh air source, do you mean straight to open air, like the filler neck, or to a vacuum source (like on one of the manifolds)

Well, oil can still be blown out, hence the term blowby. By fresh air source, I mean a metered air source between the AFM and TB, not a vacuum source. And yes, on one of the manifolds, Im not sure which nipple it is on an N/A.
