Find a long downhill, run down it with the engine on the overrun (ie no throttle), when you open the throttle at the bottom check for blue smoke out of the exhaust (poss with a friend following).
On overrun the valve seals see a long period of inlet vacuum, if they are leaking then this long period encourages some oil past the seals which builds up and is burnt when you open the throttle and gives the puff of smoke...
