Hi guys and gals: Is it better to let my 928 idle, while the oil pressure is building up, after sitting all winter, or after 1 or 2 mins, should I just hop in the car, and drive it slowly, till the noise disappears?
Thanks.

Yeah, not a good idea to just idle with clackity lifters.

For 928s that sit over-winter, I always get the oil pressure 'started':

- unlatch EZK, LH
- run starter for 5-ish second interval, rest ~30 seconds
- lather rinse repeat until I see the oil pressure needle move
- re-latch EZK, LH

I have seen 928s that, after long storage periods, will idle for 2, 3, 4 seconds before the oil pressure needle moves. That's bad juju for main and rod bearings in the long term. It's easier with plugs out, but no matter what, a starter is easier to replace than bearings.

If you run your 928 every week you'll not have start-up oil pressure delay. But, after a month or so, you loose enough oil film in the 'guts of the engine' so that the pump has to 'suck' for a couple of seconds.

Thank you, gents. Hell, I should just have Luc do this, before I pick up the car....

Our GT doesn't respond well to idling just to warm up the engine. If you fire it up, drive it too....
