Mike and Chris,
Did the car ever get badly overheated? Does it have aluminunum heads? A whole cylinder full in 30 minutes is a big leak and should be pretty obvious when you get the head off.
Jeff has a good point, though. You still have more cylinders than Arcenio, and John, too, for that matter, so what's the prob? Just pull that plug and tell him all the extra noise is a new supercharger induction system. Maybe you'll scare him off...
Or...here's an idea: No, I don't want to buy a house but I'd be willing to trade you my car for the house. My car
has beaten Arcenio's.
Then you could just show up at Byron, collect your trophy and go...well...somewhere and you wouldn't have to fool around with your motor.
Anyway, if you're going to rip into it this weekend and want some help, give me a call or email.
Lowell
