I recently bought this car(yesterday) and when i started it up this morning my girlfriend noticed some blue smoke(when it finally started) this to me indicates the valve stem seals are worn. Can someone tell me to do the oil seals will the head need to come off? or is it a easy job etc?. Also i have noticed when the car is idling and you quickly blip the throttle the car nearly dies, but if you go slow on the throttle it is fine - can someone help to diagnose the problem and help with a cure? Any help and i will be internally grateful
