    I have a 90 K5 with a 350 and tbi. It is not pulling any vacuum on the pcv valve or very little and some oil leaks are showing up. I disconnected the hose and on the tbi to the pcv and used a drill bit (not a drill) to try to clean the port out with very little results..any suggestions? Thanks

    figured it out. took the tbi off and used cans of carb cleaner. cleaned the whole thing and looks good. now it will suck a golf ball through a garden hose. angelina jolie eat your heart out.
