Oil on spark plugs

[AudiA8Quattro]

putting oil in the cyls won't tell you if the rings are ok or not

Why not? isn't that the haynes way to do it??

if you just put oil in the cyls  to see if it soacks down through you'll be waiting a long time.

Yeah i think i guessed that after my last post. Wires crossed, i was thinking compression test.
