That much oil in the intake it not normal and you should check your PCV system. Clean it out and see how long it takes to come back, then unhook the PCV and plug the TB nipple and leave it unhooked for the same amount of time it took for the oil to come back the first time. When you inspect it again if there is no oil then you found your problem.

Timing cover leaks are hard to track down. Take a can of carb/brake cleaner and spray the area down to clean it well, then check it every chance you get to see where the fresh oil is coming from. More than likely it's one of the three seals and should be easy to fix once you figure out which one. Looking at your picture my guess would be your crank seal.

 

****UPDATE ABOVE **** Thanks

 

oh yea and any tips on replacing the seal?
