estima overheated few month back due to no coolant, was fine once refilled, no there's a little smoke bluish in colour not noticible when driving though, was told cylinder head was replaced 3000 miles ago by previous owner, car as been stood since refill in december would this explain blue smoke cheers

cheers for that i am going to have to drive it about 100 miles to get it home, any advice on best way to do this should i take it easy or give it a good long run? its my first ever estima or toyota so really don't have a clue

Blue smoke means burning oil. Now this is most likely to come from worn piston rings. It could also be due to worn valve guides, this would be more noticeable on startup.
When your car overheated there is a likelyhood that it could have slightly damaged the rings (guides are less likely to be affected IMO.)
Check that you're not losing lots of oil.
check at least weekly.
keep an eye on coolant and oil and your car should run nicely.
If it passes MOT (on emissions) and isn't using too much oil or creating a smoke screen I'd basically ignore it. Getting someone to remove the pistons to renew rings is likely to cost more than the car is worth.
