Smitty,
I had a Corsa with the center mount Holley. The power valve failed when the engine backfired once. It dumped a bunch of raw fuel into the manifold and all of a sudden. The horrible death clatter began. I think the count was 4 valve seats fell out all at once. Needless to say the engine was scrambled. Ever since I use a power valve block off when I use a Holley carb. Even gas can super cool seats enough to drop out. Water injection can work fine as long as it's just a mist. But if too much is dumped in all at once all bets are off.

> Smitty says;   As I was writing about my ongoing trials with Spike I was thinking about a related issue.  When I wrote to one of my friends about loosning a valve seat he suggested that I might look to the water injection for a reason for that to happen.  The shock of moisture laden air cooling the seat and making it fall out.  Don’t know if I can relate to that or not. Warren let me hear your opinion along with that of others who have water injection experience.
