I have done some diggin on the head gasket, i believe it is blown on the timing chain side, that is why there is excessive pressure in the bottom end when i pull the clutch oil fill plug, and when i get on it it pushes coolant out, the fan is turning on and off fine and works good, was just curios if i removed the thermostat if it would effect the efi system to much, probly this weekend i will be doin the head gasket and get the head surface checked, the guy i got it from had his brother put new crank and piston and cyl on it when i got it i noticed that is got hot and no coolant so i filled it and it pushed out all over the place on the track but it can idle for 45 min and no coolant leak or pushed out just excessive pressure in the bottom like to much blow by
