Thanks everybody for the good advice. As I mentioned the budget is $50. This is because we were given a residual value of $250 for the car, so we can spend $250 fixing the problems we have. Although it's invisible to the judges we don;t feel inclined to cheat.

So we got the head fixed at NAPA. I think the bill was about $80. We bought an engine rebuild kit because the rings are shot, another $175, and our budget is now shot!!!

Plan it to clean out the radiator as good as possible. I have a good 944 radiator here and may try it. BTW Lemons rules say stricltly no coolant or water wetter.

I'll let y'all know how we make out - race is mid-Sept.

Thanks for your advice!
