Thanks for the replies. I am still learning about this engine (and engines in general), and was confused as to what the keepers and retainers actually do. I've heard of AP1 intake retainers getting busted (I still have my stock retainers) and figured this could be related.
I do not idle the car for long periods of time. My car used to burn a lot of oil (2 qts+ between changes with Mobile 1), but since I've switched to Castrol Edge it burns less than a qt between oil changes.
I plan to send the oil for analysis next oil change. I have the oil from my last change in my oil container, would sitting for two months in the plastic container affect the results? I will also try the valve stem check that Spitfire suggested.
Thanks again everyone!

Don't stress about the retainers on this car, as long as they haven't been abused they can last the life of the vehicle. It's a good idea to inspect them if you aren't the original owner.

If you're hard on the throttle at low RPMS you also force the car to run rich - possibly contributing to fuel in the oil. You're also probably changing your oil much too frequently (1500 miles? thats like every 7 tanks of fuel!)

What mpg are you getting, btw.
If the mpg is not much worse than what OEM cars get (search for it) it could all be normal.
Are we talking about the "2010-Current MY02 GPW/red, black door inserts, invidia n1 + test pipe" in your sig?
So you're running without sec. O2 sensor and with a CEL fix?
I've seen many posts of people noticing gas smell out of the exhaust with a test pipe.
So maybe the test pipe & constant sec. O2 value changes how the ECU thinks the engine runs, making it run extra rich?
The prim. O2 and ECU decide the fuel mapping, ect. depending on the throttle input - as far as I know - but who knows what the sec. O2 exactly does?
I've been running with a faulty sec O2 for a while (DD - 130 km a day) and did notice a slight change in fuel consumption, as in, it went up.
Does the old oil still smell like gas, even after sitting for 2 months?
If it doesn't a UOA of that old oil probably would show less dilution / flashpoint change.
Air filter/sparkplugs is/are in good condition?
(basically normal maintenance)
And yes, a 1500 mile OCI is kinda short, but I assume you did this to investigate?

That's correct I run a test pipe with CEL fix. I'm getting about 23-25 mpg, which I consider normal for a mixture of highway and city. The old oil does still smell like gasoline, but not as bad as when I first took it out of the car. Sparkplugs and air filter are both in good condition. I typically change my oil at ~4000 miles, but it kept coming out so nasty I decided to try it at 1500 just to see. It was black.
I've decided to send the old oil and oil currently in my car for analysis. Is there a company someone recommends, or is that something typically done local? Thanks everyone this is a big help!

I think its normal. If your not having any issues and the test comes back within spec its just normal. Small amounts of unburnt fuel gets into the crankcase sometimes. Cleaning your PCV is a good idea, and may reduce the smell a bit.

So how do people get away with running a TP with the CEL fix? I plugged my o2 sensor into the CEL fix, which goes into the TP. It could very well be the problem, but so many other people do this too. Do they all run rich? And if I continue, will it cause harm to my engine?
