If i haven't started the car for a few days i get a momentary tappet type rattle.
Is it a problem does anyone think or do they all do that sir? V12 vantage 2009.

Hydraulic tappets Dave so may need a bit of oil pressure to take up the slack. Haven't actually heard it on mine but starting it in the garage is a bit of a wall rattler! Do you leave yours a few weeks between driving?

Dont normally leave for more than a week but do notice then. Sounds exactly like hydraulic tappets waiting for a little oil.
In for a service in a couple of weeks so will get it looked at.

Catch up at the Bond evening i hope.

I spin the engine for a short while without starting whenever I take the DB9 out to allow oil to circulate without the full stress of ignition (accelerator pedal to the floor and press start).

Can't say I hear tappet rattle but it is in a garage and I am in the car so the sound of the engine start echoing around maybe muffles it.
