@RSchanz I replaced the coolant and flushed the whole system. I had to replace my water pump so I figured I would just service the whole system while I was at it. Put new hoses on as well
I agree with this^^^^.It could also be the O-rings or gaskets in the oil cooler.Yes it’s concerning need to do a leak down test and see what going on, need to pressurize the coolant system and check for bubbles. If you have the liquid from the first drain send a sample to blackstone for a analysis. Blown head gasket is a possibility

Did it still have that oily sheen after the third flush?
I'd wait until the sun is up and then check inside the bucket. If there's no sheen, then it probably was from your drain pan.It’s hard to tell since it’s night. The other flushes I did before work and the sun was sort of up. I’m not going to lie it’s very possible that it’s just oil left in the drain pan since it’s been used for changing oil in the past.
since I first posted I did more research on the oil cooler and found that it could possibly be this but other ppl were mentioning that it was noticeable oil in the overflow.
I know that there are many places to get the tools online. The test is easy. You fill up your cooling system, pressurize the cooling system and then watch the pressure gauge. If it holds pressure, then there's no cooling system leaks. One advantage of this over Blackstone is that you can reuse the tools and you can get much faster results.Where did you get the tool from Stu? I’m sure I can look up how to do the test online.
still think I’ll send an oil sample to blackstone because... why not?
A lot of auto parts store chains will have one of these kits that you can use on a tool rental program. That way, you can figure out how it's done and then you can decide whether or not you want to buy your own tester kit.
