on moorway with no oil or water in.? New oil and air filters, timing belt and air con pump fitted at service.Day after service noticed oil drips and air con not working properly. Booked in garage. Noticed a fault on air con but no time to fix it. Didn't look for oil leak. Rebooked for following week. End of week, driving home and WATER temp light came on and car over heated. Stopped, filled up with water and tried again. Five miles further, light came on again. I was on Motorway driving through roadworks (50 mph) so couldn't pull over till layby, approx three miles away. Two miles from layby OIL light came on. An independent garage inspected the engine and thinks the oil cooler wasn't flush with it's housing, The garage responsible says he can't do anything without getting the car back to them. This could cost me a considerable sum of money, plus I am worried that, once there, they could make it look like there was no leak at all. Please help.
