fuel in oil
just did the 784 "Neon" injectors a month ago.
changed oil at the same time since there was signs of water in the oil.
a week later no water... but the oil is thin and has fuel in it.
Sooo what could be going on here?

That or bad piston rings, faulty pressure regulator, or a bad firing system.
Start with checking for misfires. Then check the pressure regulator on the fuel rail.
Also take note on the oil consumption. If your burning oil you might have bad rings.
Injecters are not cheap but then again an over haul is not either.

Hi I'm Lykos, long time lurker ...
FWIW I had this issue with a vehicle years ago. A 383 Chevy (stroked 350) that was getting way to much fuel. Like a nitwit I continued to drive it.
On the way to work one morning enough fuel in the oil had accumulated that it was able to ignite. Blowing one rod completely out of the block, blowing holes in both sides of the block, breaking the cam shaft in two places and ballooning out the oil pan out so far I couldnt get a socket on the bolts.
Yeah, it was an interesting sound. Not one a Monte Carlo should EVER make.
So, in short, I'd suggest you remedy this issue quickly.
I'd start with the simplest test and do compression leak down test on each cylinder.
That would at least get you started.

It felt like a bomb going off under the hood. Then followed by me standing on the side on I24 in Chattanooga TN using every foul word I could think of and making up a few more.
Then it sounded squishy as I walked to the next exit.

LOL Indeed. I've not been to bed since yesterday at 4pm.
Work nights, punch drunk, no business posting. 
Fuels gotta come from somewhere, gotta be from the injector. Regardless of how it passes to the oil...
Pay no attention to the Noob behind the curtain...

If your calling me a noob please by all means continue to offer only one solution.
However this noob offered more then one solution and started with least costly. Buy new Injecters and be down $300 only to find that its as simple as adjusting the regulator or had to replace rings.
Anyone can state the obvious. But to offer more then one solution... That does not sound like a noob.
