Hey I finaly got a hold of a boost leak tester, to test out my new innercooler setup ( bushur deleux core setup) on my evo 8 and i found that i had about 5 boost leaks, one on the upper innercooler pipe, one on the lower innercooler pipe, one im my core, one on a vac line, and one comming out of my throttle body shaft. its a smaller leak, but it goes away when you apply some pressure to the pully )where the cable connects) twards the drivers side of the car. i was wondering if there were any rebuild kits to seal that shaft?>?>? It is a smaller leak and i fixed the rest, just i know they add up. trying to be thurough.

www.machv.com sells the new seals you need. They are $10. Its actually a very common leak. There is a big thread on it somewhere. They are relatively easy to install as well. Id worry even more about fixing those other leaks, especially the one in the FMIC core.

 

I've already talked to buschur about the leak, its brand new the said they'd fix it for free i just have to take my car down and mail it to them and wait. I'll fix the other leaks when i get a chance.

Weird. I got my Buschur Race FMIC core and it leaked too, had to send it back.. they did pay for the shipping though, so it didnt cost me anything, but thank god my car isnt my daily driver ya know.

 

curious where did you source your boost leak tester? I've been looking for a source on how to make one, unless you wanna help out tom since I live in brick now lol

 

Very easy to make. You can use stuff from Home Depot to make it, or if youre lazy, MachV.com sells them.

 

I barrowed one from a freind, im the process of making my own.

Make sure you do the boost leak test while holding the throttle open.

No car will EVER make full boost when the throttle is closed. So why check for boost leaks that way?

I suspect many people are replacing their TB seals based on a misleading test method...
