Upside down engine

If a car is rolled and sits upside down for a while - what are the implications for the engine (if any)?

Also - upside down - is there any possibility of water and oil mixing?

Well this is a K20a engine, and the instant it lost oil pressure it'd cut out.

So should be intact.

why would a car be upside down for extended periods, you buying an engine that way left upside down in a field for a few hours or something? Surely no-one would store an engine upside down?

No, tis an argument presently occuring in another dimension (grid reference www.itr-dc5.com).

EDIT: Just read your reply, should be ok if it cut out, being upside down not running should do nothing.

That's my take on it too.

I would be worried about fluids mixing, the fuel cuttoff should activate once the car is tipping so will kill the engine, the fact slight lubrication will be lost isn't an issue since the time without a full oil supply will be so short.

You mean you wouldn't be worried.

Yes, intertia switch kills the engine and also oil pressure has to be maintained on these engines. If pressure spikes outside accepted parameters - rpm is instantly limited, if pressure loss continues - no ignition.
