Hi everyone i'm new in this Forum i just bought an evo 4 a couple months ago, i'm from central America btw.
I felt that the car lost some power and did a boost leak and found a leak on the throttle body, can I do something to fix it or do I have to replace the throttle body.

The car is basically stock and here are some pics, hope U can help me





Before the bubbles made by the leak<br/>

 

I'm guessing it's leaking at the throttle body shaft seals yes they can be replaced it's not to bad of a job Google works throttle body seals or you can get the mil spec ones

 

And this seals are the sames for every Evo? Are the going to fit my E4 ?

 

I just replaced my seals with the milspec tb seals on my Evo 4 TB. So yeah, the seals are universal. There are a few little disassembly differences from the 7-9 TB but for the most part it's the same. Don't forget threadlocker on the butterfly valve screws and to properly set preload on the throttle.
