The last couple of times i've started my car up, i get what looks like blue smoke coming from my exhaust, i've had a look under the bonnet but cant see any leaks anywhere, and the oil etc is all fine. Am i worrying over nothing or could there be somthing wrong with the car!!

Most of the labour charge is taking the head off, I hear you can do it yourself by coiling clean rope into the cylinder via the spark plug hole, which the valves then rest against while they are disconnected from the rest of the valve train. That saves a lot of effort I would have though. I've never done this but it's the way I'd try and do it.

Is this only when starting the car after it has been stood cold for several hours? That's what mine does and I'm near 100% sure it's worn valve stem oil seals.

 

Contary to what folks say about about not removing the cylinder head to change the stem seals, Chris Wilson says you are probably better to remove the head to do this job.
