My truck is dead

Greg,
After reading your last post... change your oil.

Greg,
After reading your last post... change your oil.

It is on my ever growing list! At the top of it... Like first thing in the morning. I am going to save it, just in case...

it was a short time, but panicking i was mashing the throttle to keep rpms up enough to move the truck safely off the road. So wide open throttle for good 15 minutes. Several failed attempts to restart. I am sure there was enough fuel to raise level high enough to be whipped up by crank.
As far as disappearing excess fuel... I think the 3 hours sitting(allowing separation) then being started and test driven, then left idling took care of the extra quart or so of fuel.. Which first tech reported slight high but in safe range.. Then it was left idling again, test driven (total of 50 miles) and fluid levels reported as normal.

Failure analysis is a major component of my job; I always have to look at likely, plausible, possible, unlikely and impossible.
If you dump that kind of quantities of fuel in to the combustion chambers and some of the cylinders are still firing with a mixture this impossibly rich, over 99% of the unburned fuel will go out in to the exhaust, not past the rings in to the crank case.
If the raw fuel can get past the rings, you don’t have any left!

So that is why it sounded like a chevy vega with glass packs running on 3 cylinders...

But since the engine was cold and not warmed up, the piston to block clearances are a lot looser and will allow fluid to pass through. That is why you have piston clatter during a cold start..

That is not how it works; piston rings have an overlap arrangement, especially the multi component oil ring.
The expansion of the rings and the cylinders is almost equal, the ring gape stays almost the same cold or hot. This is not an all-aluminum engine.

Must have burned up extra fuel ******* the tow truck... Lol

We will see tomorrow when I dump the oil...

Dumb question. Will passing lots of unburned fuel out the exhaust destroy the cats? O2 sensors?

over 99% of the unburned fuel will go out in to the exhaust

Foamy oil will displace more volume. If you were a quart high and the oil was foamy, I highly doubt that "quart" was all fuel.
