Hi,
been trying to identify the source of this leak on cyl 6 on my 3.2l '86, in order to estimate whether it is an engine out kindof problem or not.
Photo from below, where you can see the symptom - a small slow leak onto the exhaust flange and bolt. It is a very slow leak, and in itself not a problem, but I don't want it on the hottest part of the exhaust for obvious reasons.
Closeup on Cyl 6 exhaust area:
In order to find this, I went and got an endoscope, so I could get into the area below the air shroud on top of the cylinders. I filmed through the fan and into the area and you can see the larger cooling fins on the right. I know its hard to make out but it's the best I could do. In the gap between the cylinder head and the smaller cylinder wall fins I had expected a pool or trace of oil from somewhere but alas... the only thing I can see is that the back wall (the side of the oil cooler?) is kinda dirty, indicating oil and thus dust sticking to it. That's my conclusion, that the oil cooler is leaking, would anyone care to agree? I don't know what is "normal" in here. hence my ask for a second opinion.
