Edit: The car is a mk4 golf 1.8t AUM
Hi all, after a recent coolant change/top up my car has been emitting a slight burning/hot/candle smell. Today the smell got increasingly worse as I was idling outside my house and I opened the bonnet to see what could have been a light mist of steam. Further to this my oil filler cap has a light coating of moyo on it. Now I guess the head gasket has gone/is going? This may be due to a slight overfill of coolant which I aim to correct tomorrow.
Do you all reckon its the head gasket? If so how much can I expect to pay in repairs? I might have caught it early as the engine still runs perfectly.
If anybody wants to earn a bit of money and lives near Bath let me know. I can't afford to have a garage do it (I'm only a shift manager in Pizza Hut)
Thanks!
