Good luck!

Mine no longer leaks there, but I still have other problems.

If you are not exprienced in car repair or modding car do not try to replace the seals in the tb. Just call buschur and buy one of their ported tbs. If you dont do the seals correctly you will be up a creek. Example if it sticks at wot. Big problems. Please double check your MBC lines to make sure it is hooked up right. Pressure source should be on the bottom and the line that goes to the wastegate on the side.

 

fixed the boost leak. now during hot weather im boosting at 18-19 and back up to 21 at night. thanks for the help

 

its an easy repair. no need for an experienced person to do it or to buy a whole new one. and when someone like me who has hardly any car repair experience is saying it then its really easy.

 

^so... what'd you do to fix it..?

 

^Sounds like he replaced the throttlebody seals.
