On start up i saw a cloud of smoke form about 10 metres in diameter, had a blue grey tinge, after the initial smoke subsided, there was a continous pour of smoke that was still an abnormal amount. The smoke mostly cleared after warming up, but a little amount was still consistenely there. I drove it around the block and smoke was not visible behind me. Thanks for the info, i will definately be doing a compression test before i go and change seals.

Thanks heaps
