It's not unusual for these engines to haze a bit on initial start up until they warm up a bit

oil leaking into the cylinder will make blue smoke cause: Valve seals worn valve guides.

You can do it yourself with a spring compressor might as well put a good set of springs in it to! Cost to have a shop do it not sure but under 500. I hope! Alot of work to get to them!
