After in ran steady for ten mins in safety of neighbours rear drive, I thought i would chance it. However when i set off driving it was blowing thick white fumes and so went to garage instead.
They kinda confirmed it was oil in exhaust etc and had a look....
Damn, just checked the oil level and its user error! Put ermmmmm a little too much oil in.
Now pricing up full replace of exhaust n drain some oil......yep feeling foolish and a loss in pocket
Hopefully its being repaired this afternoon or if not first thing in morning. Now I get to go home n face the music from the mrs
