Doing wonderful. Not even a hint of oil. I've blown off the sensor a couple times and have one small, persistent spec that's only noticeable at small apertures against a solid background (sky, painted wall), but it's just normal dust and immediately fixable. I'll wait until a wet clean is really needed. I've even been shooting in Continue High mode lately, which immediately made the spots present in the past. I haven't checked the shutter count, but I'm at least five hundred frames in since the repair and no complaints.
As the line from Poltergeist goes, "This house is clean".
