Alright guys, I'm lost as to this one.
Picked up the combustion leak detector kit from napa. Watched a video on it. Seemed pretty easy so I got home and gave it a shot. According to the test I have no combustion gasses in my radiator. Just to make sure I was understanding how it worked I went and sucked up some of the exhaust. Sure enough it turns yellow so I must have been doing it right.
Tried to figure out what all I'm doing wrong. I have to be leaking from somewhere as I found some coolant drips on the bottom front of the engine, both sides. I also noticed that even after letting it idle for 10-15 minutes, I had no pressure in the radiator and could pull the cap with no issues, so I'm leaking from somewhere.
But that's not all. My exhaust is still "steamy" to me and I had a good water drip coming out of the exhaust.
I grabbed a flashlight and started searching for drips. Couldn't find where specifically it was coming from. I did find some other concerning things. The manifold from the #4 cylinder appeared to be leaking, probably oil? It was darker and more rusted looking around it. Then when I crawled underneath there's actual oil or an oil/coolant mix coming out of the manifold.
Last I drained my oil to see what it looked like. It wasn't white and foamy, but definitely more of a dark brown "creamy" look to it, and definitely more of a watery consistency than I would think oil should be. Some of that could have been that it was warm but I don't know.
Here's some pictures of what I found. Let me know what I'm doing wrong or what else to look for. I have no CEL or codes or anything like that.
