Diagnose what's wrong from this picture... (Head Problem)

This is the exhaust manifold off the passenger side of the engine.  Notice the grayish color of the tube for #3 cylinder.

That means nothing. You can't read a.i.r. tubes to determine internal engine problems as it's post combustion. If that tube isn't flowing as much air it won't look as clean as the others. Read your plugs instead.

I actually haven't removed the plugs yet but I will.

Just to note, 7 of the tubes were for the most part white, that's why this gray one stood out like a sore thumb.

I'll pull the plugs this weekend and do a compression check.
