Did this ever get resolved?
Hi, just seen your post, about the car stopping as soon as the temp goes above C. Black liquid coming out of Exhaust and drainned 5L of oil from Engine.
It sounds to me like a Cracked block or Head.
Please let me know if you fixed it? I got problems too with my micra, but if people are going to respond saying change HT leads plugs points to your problem. I want to know how helpful it was.
Thanks
Chris
