147 2.0 TSpark, blue smoke on startup
I have a 147 2.0 TSpark, 86k miles, 52 plate. I had it seviced by my local garage a couple of weeks ago and it's been running great. I took it out for a spirited drive on Saturday night and when I started it up on Sunday afternoon there was a bit of blue smoke coming out the back of the exhaust. It cleared after about 30-40 secs. It hasn't done it since and my oil level is fine although I'm now paranoid the engine is going to go pop.
If it helps it's using Valvoline 10w40 Semi Synthetic. Also it has been used for mainly town driving and this was it's first proper run for a while.
I'm just wondering if anyone has had anything similar happen or has any ideas what could be wrong?
