83.3% combustion

So, let's say I had a six cylinder car, and due to a misdiagnosis on running, I thought I had a fuel problem I could drive out, but in REALITY.. I had a bad spark wire on cylinder no 6.
And the car was driven possibly 40-50 miles, with lots of cold starts.
So, lots of fuel, no burn on one cylinder.

What's the permanant damage?
I went and did emissions this morning, and passed fine.
However, I think the car is slightly down on power, and I did turn my pretty white bumper yellow from burning the paint.

cooked cat, burnt valves, fuel running past the rings to the oil, thinning it?

You would wash down the cylinder not firing. It would cause the oil to thin out, but the real damage would be the cyl not firing would get all scarred because there's no oil in there.

it's a flat 6, I'm hoping it all the gas fell out the exhaust port.
