I have an a41.8T 97, love the car, but through deprivation of oil doing about 70-80 mph, oil light came on, I ignored it as it's not the 1st time, but 50 miles later, seized, what's the likely out come, no bits or oil seepage, cracks blue smoke, nothing just loud tapping from engine then I knocked it ultra gear it stalled and coasted to side of road, new engine or rebuild?
