I ended up using 3 pour cans of B12 and a full case of "25% more" non-chlorinated brake cleaner. A pick set ,small bristle brushes and scotch brite pads are useful additions for nasty conditions .
I bought the car in July 05 with 49K - UIM/LIM was done at 51K. 500 miles a month average - I can probably go awhile before repeating the task *knock on wood* . A catch can will help minimize the goo from reforming . Maintaining the EGR and PCV system goes hand in hand with this . Not that I condone emissions equipment removal - The EGR along with vapors from the purge tank are Huge culprits to this build up . As always --- YMMV
