1G FIAV/ISC

[bagii]

I had something interesting happen today. I pulled off my throttle body and was cleaning out my fiav/isc. I noticed that the o-ring for the little motor was completely detiorated and could be the source of a vacuum leak that i've been chasing for awhile now. so, obviously i didn't have that same o-ring close by so i used some rtv/gasket maker to seal it up. I reinstalled everything and went for test drive. everything seemed fine until BOOM! something blew loose like an IC pipe or something. the whole drive back something sounded like it was sucking hard and idle was up at 3000. I got back and popped the hood and found that the little isc motor had blown off the TB. the 2 bolts holding it on were still on the TB. it had broken the aluminum ears off of the ISC motor. I didn't overtighten them when I initially put it on. Has anyone seen this before? It was pretty nuts.

WTF Holy shit sounds worse then my problem with my damn TB! ISC blowing out of TB.... man that is something new.oh yea NUTS!

I know, pretty nuts. I'm kinda hoping for some insight. Should I put another ISC on there only to have it blow out again; or should I just put a block-off plate on? decisions . . . decisions . . .

holy shit! thats awesome . how much boost were u running?

 

[steve]

The only time I've ever broken the mounting ears off an ISC is when I put the o-ring on the outside of the body and tried to bolt it in. Just trying to compress the o-ring was enough to bust the casting.

dude that is weird stuff. never heard of that b4

 

[bagii]

No, it was not boosting high. its the factory turbo setup. anybody have one of these laying around or maybe the block-off plate?

Looks like you just over tightened the bolts and just busted under load! Yea i have one just came off working car PM me an offer man
