Smoke coming from cylinder 8 area
Made a quick video. https://youtube.com/shorts/K7dGugQOBUo?feature=share Smoke doesn't look like it's coming from the spark plug. Just below it to where I can't see. This randomly started after sitting for repair. Smokes as soon as it's started from a cold start here in Montana. Not too thick. Hard to tell if it's a sweet smell or oil. I live in the mountains and our 1 mechanic is out for good. Trying to save a 2 hour trip with smoking issues.

That's usually oil leaking from a valve cover or whatever. It runs down the side of the head until it gets to a point that's hot enough to make it smoke. Look at it with a good light and maybe a mirror just above where the smoke is coming from. Fresh oil is glossy, old is dull because it has dirt stuck to it. When you find the highest point of the trail you've found the source.

Check your heater hose connection at the heater core. Do you have a rear heater in it? If so, there is a T connector there as well. I just had to replace the T connector in my Tahoe. Coolant drips right down on the #8 coil and right down on the exhaust manifold.

I'll check that out as well. Trying to get through the busy holidays first and then knock that out
