well thought id give you guys an update, the car is fine (touch wood - (let the stupid comments begin about that phrase) i did a full coolant flush last week, ran the car with some rad flush in then drained it all, ran the hose pipe though the engine, took the radiator off and pressure washed the core and got LOADS of gunk out. changed the thermo and re-sealed the housing. so im assuming that the rad must of been partly blocked (as it was second hand when i got it) which was fine for road use but soon as it got on track over heated. which is good news but means i dont have a JAE ticket as wasnt expecting to have the car. fixed the handbrake, it was the cables so the exhaust guys must of heated them and fucked them whilst heating my exhaust, so need to go down and have words as a slight exhaust tweek ended up costing me new handbrake cables and to rear calipers. and its mot time tomorrow so fingers crossed for that. so now just gota wait for some1 to sell there jae ticket to me!
