Try rinsing it again, blowing it with compressed air to dry it, then put some baby powder down there to see if its new or residual. Has your idle changed or started to stall or bounce at all

Sounds like the oil control rings on the pistons are bad. Does the car smoke under a load? My last motor had perfect compression on all cylinders and even passed a leak down test. Did a re-ring and re-hone and all was good.

So, if it does turn out to be the rings, I'd have to get new pistons as well and step up to 84.5mm?

I didn't rinse that side, but I will. The idle is fine and the car runs OK.
No, I haven't noticed any smoke behind me under load lately. It wasn't full throttle tuned for quite some time, because I had to break in my Kevlar clutch. I wasn't able to boost or go over 4000 RPM during that time. When we did full throttle tune it, there was black smoke from carbon, not oil. How would oil get on the injectors if it's the rings, though?
