apparent tappet noise on start up ?

[Craig Mack]

Hi all

My VY SS has just started making a apparent tappet noise for a second or so after start up but disappears shortly after starting , this has started appear just after I had a service and for the first time I did not use Militec metal conditioner in the oil change ,, The strangest thing happened first as when i went drive it the next day after the service , I got a hundred meters from home and the management system told me i had no oil , I pulled over , Checked the dip stick and it showed no oil , , I Walked home and got oil and added it ( 1 Ltr ) till it showed on he dip stick . taking it back to the mechanic the next day, he drained it with a measure taken and it should one Litre over fill .
And now I have this tappet noise on start up that disappears just as quick ,, Oil level is Ok Any thoughts please !! . Craig mack

what grade/type oil did they use and how many k'ms are on the clock, where you on a hill when you measured the oil and the warning went off?
