Intake
98 Jeep Wrangler 4.0- So, I started out to replace the coupler gasket
on the exhaust and found out that the exhaust manifold was cracked up
pretty bad and had some very bad welds from the previouse owners fix to
it. After pulling the intake I noticed that the #6 port was almost
clean, absolutly no carbon, but all of the others were pretty well
caked. Would this be a bad valve, broken rocker, dead injector ie...
clogged or electrical issue? Or am I just LLMF?

#6 is the hottest running cyl. Furthest from the air and coolant and
usually is clean. Carbon in the exhaust header and ports is fairly
normal. Usually the result of an old O2 sensor that's causing the
engine to run rich. A broken rocker you would hear from inside. :)
Time to get a drop-in. I went with Banks but it required a bit of
grinding to clearance the motor mount.
