[DeTomaso] What caused the Dawg's engine failure at SilverState???

Tue May 30 00:51:10 EDT 2006

Crazy Dave,

Do you really change your RINGS, water pump, and Clutch/PP every year?

Are you coming to SS in September?  I hope so.....

Learn from this, When you race, some things must be changed often.  
Oil - Every race, 
Fan Belts - Every year,  
Hoses - every Year,  
Coolant (if you run it) - 
Twice a year,  
Trans oil - Every 5 raes, 
Air filter - Every Race,  
Rings - At least yearly,  
Water pump and Thermostat - Every year,  
Clutch/PP - E every year,  etc.  

Remember, racing is expensive if it is to be reliable.

hatch 'twice' to look at the belt and adjust tension although tension
was
set perfectly....both times it looked okay. I haven't lost a belt in 20
years.  I had Drenske look at it and another wrench in another  shop who
set timing and rejetted carb just before SS to also check tension and
check
the belt.....it looked good....everyone said it looked good and tension
was
good and life was good.  So the moral of the story is do NOT listen to
anyone when your belt starts talking to you. What it was really
squeeking was;
