the inter cooler takes in unused fuel cools it and puts it back into the engine . so its black and oily it will be mucky around the crack. have a look with the engine running . you said you could feel air around the cam belt? around that area push and pull hoses and pipes etc . see if you can locate the problem that way. if you do . cean it off well . i did and used 2" wide tape to seal it up . if this helps rate me thanks joe

You have to locate the cable between the heater core box and dash control knob most likely it is hung up someplace in between if you can straighten it out it will give you more cable length also look to see there may be a loose spring that need to be reattached.
wear safety glasses and get a good light you will need screw drivers needle nose pliers snap ties to hold cable in place

Sounds like you have a clogged PCV valve thats the valve that lets the gases that get into the crankcase be rerouted back into the intake. It's silver about two inches and is usually in a rubber fitting in the valve cover and will have a hose on the other end. it's no tools installation just pull the hose off pull it out and replace with a new one. thats the first thing i'd do - 10 mins and 10 bucks should do it

White smoke would be an idication of coolant in the combustion chamber. Check coolant level,check oil to see if it is a milky color.May be a leaking head gasket or possible oil cooler leaking. Let me know if this helpful
