Title: help with greddy ext wastegate..
Post by: karl_tate on December 21, 2008, 03:07:10 PM
i have taken my external wastegate apart today and found that im running the yellow spring, which i think is the 11psi one.

i was getting a little bit of creep before but now i have found that the diaphragm has a few little holes and marks where it has worn.

just wondered where i could get one, and if i need a new one?? could this of been causing my boost creep some times??

cheers

holes in the diaphram are not good, your lucky you only had creep.  Did it cause your engine to pop?  

Definately change it, i\'m not sure where you get another one from though

no was not the cause. it held fine most days.
 
are we talking about the same one, not the black one, (i really dont know much about wastegates) its the orangey colour one inside when you take the spring out.
 
i did think about taking a photo, will get one uploaded.

the black one?   normally a rubbery thing sandwiched between the lid and the body of the w/g under the spring
