@Macd7919 I was 90% sure I was using the correct terminology there lol. I am curious about that exhaust routing way since it does seem like the best idea to me. Isn't the whole point of the reroute to NOT run that back to the intake? That's the impression I was under for doing the mod, or in my case I was wanting to get rid of that whole box and filter the have on there.
No worries! Yes, the advantage to the CCV reroute is getting the oil out of the air stream. If you replace your intercoolering piping (a full kit with the intake manifold replaced as well) you also have to do the CCV reroute as there are no longer provisions for it on the aftermarket piping. With that said, the OEM CCV filter is known to get filled with oil and not do a great job of filtering (hence the oil that gets all over everything in the engine with the factory CCV). Going to a catch can or the baffle version (which you have) is supposed to cut down on the liquid state oil being passed through the system, which is why CCV reroutes without a catch can or baffle tend to drip a little oil under the truck from the reroute hose. The catch cans/baffles don't necessarily help with the smoke/odor though. That's where piping the reroute into the exhaust or intake comes in. You get rid of the "liquid" state oil with the catch can/baffle, and then deal with the smoke/smell part of it by dumping the reroute hose into the intake or the exhaust. Dumping to the exhaust seems to be the more popular option of the two, on this forum at least. My personal hesitation on the exhaust method is that the venturi (the fitting you add to the exhaust pipe to put a small vacuum pull on the CCV hose) seems to be quite finicky on position and angle with no real data on what works best outside of trial and error. I guess you could install it and then just through a vacuum gauge on the hose to make sure it's pulling vacuum but I digress....On other forums, there are people with it piped to the intake, it seems to kind of flow with whatever the popular option for that particular vehicle was at the time people started delving into CCV mods for that model. Anyways, I'm waiting on the parts to arrive for my reroute but what I'd like to do is confirm that I'm eliminating the majority of the liquid state oil from the CCV airstream via the catch can/baffle (granted, there will always be some vapor in there, which I personally don't care about) and then plumb the "clean-ish" CCV back into the intake arm, or possibly just feed it to the airbox. I am slightly hesitant to go the airbox route as I would like to maintain some level of vacuum on the CCV and I don't think the airbox route will get me there, but, it should help with the smell as it would get sucked straight into the filter. I fully understand this will not keep 100% of the oil out of the intake tract (or potentially the filter) but if it reduces it by 75%+ over factory, and I don't have to deal with smell/smoke/dripping then I will consider that a win for what I am after. Anyways, once the parts come in I will post up more on how my proposed solution works, most likely I will start with the air box version and run that for a week or two to see how it goes and if that isn't fitting the bill then I'll tap a fitting into the intake arm and try that out.
