Granted, we're talking about added complexity, but it > sounds justified in this case. You can buy such a device, and plumb it into your car. It stores a quart or so of oil under pressure, which you can release before starting the car. These can also be rigged to release if the oil pressure drops, say if you are doing a sustained high-g corner and the oil goes away from the pickup. In addition to added complexity, it's added expense, added weight, and added stuff to find room for under the hood. Seems like the easy way to take care of the first problem is to use an electric oil pump, and switch it on a few seconds before starting the engine. (If you're worried about an electric fuel pump failing, hook up something to kill the ignition/fuel pump if the oil pressure is low for 'n' seconds) But this isn't really needed, as engines tend to outlast the body. (Even if you don't live in the salt belt, er, snow belt, there's all those bozos running into you) Snoopy (ECS Ronin #901) tektronix!tekecs!doghouse.TEK!snoopy
