renault clio 172
I recently fitted my new stainless exhaust and noticed a cloudy liquid dripping from the CAT/centre pipe joint. I took the car down the local garage and they said was nothing to worry about. A few days later I noticed a fairly nasty burning smell after running the car. The oil colour still looks normal but my coolant level had dropped, so I topped it up and monitored it for a few days .... no change. Now, a week later my level of coolant has dropped again and the burning smell come back. Any ideas?? I'm thinking head gasket :S
