if you take the TB off clean the living daylights out of it.

new T's and vac lines, cause your gonna break a T, its just par for the course. the only T's ive found are the ones at advance auto, its a 2 pack with 2 small white T's for 2 bucks. works perfect.

if your valve covers are leaking, theres no better time then during a lim job to change them.
