Hello, welcome. My name is Mike, I will do my very best toassist you with your question.
Is the vehicle loosing coolant?
no i checked this too, and the temp guage is ok.
The fumes are coming from the right hand side of the engine at the back.
I did crawl under the car to see if i can see anything and nothing is dripping.
I did wonder if it was the exhaust pipe as I recently had a new back box fitted?
Yes with nothing leaking to cause the smoking,this would indicate that the exhaust system is over the allowed temperature and is causing the smoking.The exhaust system should be checked as a first step for the temperature and the proper flow.
Do you know of freelance subaru mechanics?
or an organisation that provides this service other than a subaru dealer?
I meant the freelance subaru mechanic to look at the car overall but from what you have said they don't exisist.
What would be the second step if it was not the exhaust system?
Thank you very much
Sorry , do you know roughly how much it would cost to replace the head gasket?
