| Ok to pull the ozone generated in an ignition distributor trough the PCV system? |

I'm also unsure of how you hope to plumb a distributor in an airtight way, but I would expect unmetered air to be entering the manifold. And lastly I would suggest there's a reason why literally noone does this. --- End quote --- You're assuming I'm talking about an engine with a points distributor and a MAF sensor for EFI? how many of those exist? |

It's really not the biggest issue in this situation. |

Towards the late 80's and early 90's there was a crossover period where the electronics weren't keeping pace with emission demands. For some reason injector and ignition outputs were costly (I dont know what the problem was, maybe lack of computing power), it so you saw all kinds of combinations including a single injector output (single point injection, essentially glorified electronic carburetors) and distributors. |
