I'm an idiot and did a whole bunch of somewhat spirited driving on a lake. Heard some nasty noises and while limping home, rods escaped. Thinking the oil in the pan was flung to the outside and the pickup sucked air. Since I was having such a fun time in the bright sun, if the low oil pressure light was on, I did not see it.
Swapping in my new engine had me thinking. In my job, we have shutdowns for everything, why not Subaru?
Idea: use the n/c to ground "low oil pressure" switch to interrupt one or both of the ignition and fuel components in an attempt to stop the engine before it makes a window. Not really here to argue if it would stop it fast enough to prevent damage. Just looking for opinions on what would be best to interrupt, fuel or spark or both.
Fuel = a potentially lean condition for a moment.
Spark, could see a washed cylinder.
Interrupting the key switch will kill both, which is my front runner. Any opinions on if that could potentially cause damage? I've never just "turned the car off" while driving under load.
I would have a momentary override switch for starting, as obviously there's no oil pressure before the engine starts turning. (Bonus antitheft?)
Spitball over, let the flaming and trolling begin! great to be back in the Subaru world again!
