Make sure it's a fracture and not a casting line. The castings can look broken, and moreso when they've been under the hood and have gotten all nasty.
As for the seafoam to really do it's magic, you need to run about 1/2 a can through the intake. I usually just pour half a can into a dixie cup, and put about 4oz of water to mix. crank the car and dip the vacuum hose in the cup. You have to let it take in a little at a time or it will choke itself out and you'll have to crank the car again. If you take your time, it should about 20 minutes and tons of nasty crap will blow out of the exhaust. There won't be a living mosquito for miles.
I use water mix so it "steams" the crap off the valves and pistons while burning as well, it's never failed me.
Once you've done that, then perform the regular tuneup, cuz the plugs will be damn near shot.

I wouldn’t advise sticking the vacuum tube in any kind of liquid. You can very quickly/easily http://en.wikipedia.org/wiki/Hydrolock the motor if too much fluid is sucked in too quickly. I use a funnel and slooooowwwwwllly pour the liquid into the vacuum line instead. That way you can better regulate the amount of liquid going into the engine.
Another tip is to stick something on the gas pedal to keep the motor around 2k RPM’s to help avoid stalling out while pouring the seafoam in the vacuum line. I prefer the vacuum line that goes from the upper intake to the brake booster.

Ok. Update time. Upstream o2 sensor bank 1 was real bad. Range was only from around 12 to 110 or so. Had both upstream sensors replaced. Installed CAI this morning. The shop told me give it a day of driving before I notice improvement with new sensors. They were right. MUCH better! Gonna fill gas tank up to track mileage and see where we are at. Gotta put new muffler on today too. Just going stock single for now, until I get shorty headers and true duals. Was thinking X pipes. Michigan doesn't have emission inspections, so my options are pretty open. Have not done Seafoam treatment yet, cuz I need the time to change out wires and plugs too. So far so good!!!
