Nice! I'm learning a lot! This will be most helpfull, as I'm planning to put an LT1 in my wagon.
THIS^^^^^^Though some might think that coolant kills optisparks and it's worth tapping and routing this hole away from the distributor (and I've done that in the past), I doubt it. I think the real optispark weak point is busted vent harnesses, and the seal around the 4-pin harness failing and allowing oil in. I see oil inside optisparks far more than coolant.
OOOOOOOF!!!! That sucks! Glad you got it out!
i'm very curious to see how this works! I actually live in Phoenix AZ, and to be honest I've never noticed an MPG drop in the summer. But I'm sure I've just never noticed it, and since summer is approaching soon ill try and keep track of it this time.I'm actually thinking of spraying the bottom of my gas tank silver to reject asphalt heat; if you watch your fuel economy, it goes down as the gasoline in the tank heats up. I remember our family road trip through the American Southwest in June how blisteringly hot the pavement was. The fuel pump in my minivan whined so loudly out there, and in the 60,000 miles since, it's never been as loud as it was in New Mexico and Arizona.
