Needing confirmation as to if I need to tear down and rebuild my Renesis!

Would a catch can suffice if I don't need a rebuild?
What if I bought a 6 speed automatic from a 2006 model, transmission and the Engine. Would I just be able to drop it into my 2004 base model, aside from the obvious exterior components that would be different. Are the chassis and stuff different on the 2006 6 speed automatic as opposed to my 2004 4 port auto? I've heard the Automatic transmission on the 06 model is far superior top to bottom so if possible if I HAD to rebuild, instead just drop a 2006 auto both engine and transmission So I'm not just rebuilding an engine with inferior design flaws. Or is the new filler neck interchangeable?

Given that this engine only revs to 7k, the best theory that you have a failed side seal that's causing excess crankcase pressure and forcing oil out the PCV/filler neck. Compression test (a proper one) can confirm that.
The only bit of this story that doesn't fit is that this happened suddenly. Seal failures usually manifest over time. Apex seals can fail suddenly, but side seals? That's odd.

Yeah the '04 4-port auto is worst version of the Renesis. I didn't realise this is what you had. The 06+ auto engine and trans swap would definitely have more legs than just fixing what's there. I'm just not sure if the 04 ECU can drive the 06 trans.

The only problem performance wise that I've noticed is once I would ever hit 105 mph or so is when when the power through the gas pedel just seemed to just vanish around 4500-5000 RPM's and with the pedel on the floor, speed and RPM's would raise at an almost unnoticeable pace. Which is odd because when the exhaust/ headers/ intake etc was all still stock I was easily hitting the 105 MPH mark with plenty of power still climbing at WOT all the way through 120+ MPH before Id have to let off, on plenty of speed runs. Sounded incredible with no hiccups at all. Perhaps in desperate need of a good Tune? Never had it happen until after I put the new new manifold and catback on (which was recently) and ever since I noticed it the first time 2 week or so ago I've only tried opening it up 2 other times (lots of long straight highway stretches around my area) just to see and each time it was the same thing, extreme power loss after I slip into 4th. So I stopped doing that all together because it truly did not feel or sound right at all. The last time was 5 days before this incident I'd say, drove flawlessly otherwise. And then this happens. My gut tells me it isn't compression related. I'll get the B585 conversion ignition kit in the mail soon and update then go from there. Without a genuine Rotary tester I don't mind throwing parts at it given that they will be parts that I need if/when I need to rebuild or replace the engine. I'll run a regular compression gauge just to make sure the engine has compression, rather healthy compression or not we shall see. Again, thank you for all the info!
