boost leak in TB

[apckofllamas]

i have replaced the shaft seals twice now and it still leaks horribly, i have taken it apart multiple times and used dielectric grease to lube it up. i cant seem to get it to seal. it leaks from the TPS sensor, if anyone else has ran into this problem what was your solution? thanks

a buddy of mine had the same issue. but after trying to seal it over and over again, he finally took it apart and set it on a work bench. with a good light he noticed a slight crack in the tps sensor instelf and replaced it. put the tb back on with high temo rtv and car ran like brand new.

ill take it back off and look over every square millimeter for some kind of slight crack, ill post back with results.

i looked over my tps didnt really see any cracks and switched it with another one i had and still the same problem. i rtv sealed it back on and there is still a massive leak. it feels like it is coming from the sensor when it goes into the tb, im not sure where to turn next.

do you have another tb or a buddy with one to swap with. i would just make a pressure tester and get a couple for the pipe that comes off the tb. clamp it on, get a bottle of soapy water, put pressure in the system and go to town spraying. you will find exactly where its happening and should be obvious why

i have an extra one and i did swap them with the same results, im waiting on the new shaft seals and om gonna have one of my buddies put it together because apparently im doing something wrong
