[V8] ISV final fix

[toml99 at todomundo.com]

Awsome Dave, nice when it's something cheap and simple and glad it's  
running fantastically.  Did you cut the filter open?....When I  
drained the tank on the parts car, I was amazed at all the stuff in  
the tank...Not sure if it was some kind of coating peeling off, but  
it was full of black flaky material....I didn't bother cutting that  
filter open, but am sure it was full of that black stuff.....Cutting  
them open is always a satisfying experience for me, because it's  
never clean.....My Duramax filter interval is 15K  or so, and I'm  
always amazed at what's in there in that short of time....Tom
