Keep us informed if you would.
I always like to know outcomes and causes.

Of course. praying for bad gas.

Still waiting to hear back from the dealership. I have a claim open with racetrac, so everything is set if they determine gas caused the damage to the engine.

I’m not going to lie i’m very nervous, but while i wait to hear back from them i was wondering if you guys had any thoughts on what the cause could be.

Basically, what do you think could have caused two cylinders (one and two) to die instantly and have zero compression?

My theory is, maybe low grade fuel or water caused a rapid change in the engine timing, detonation, possibly a cracked head or chipped or bent valve, or water spraying onto the hot valves causing a a valve to chip or warp.
I keep leaning towards bad gas simply because my tank was empty (gas light on) and it broke while leaving the station.
whatever the cause i know it was catastrophic, and there was no indication at all of issues prior to filling my tank.

Pretty tough to say without a visual inspection of the internals.
Water could do it. It (steam) can cause some very high pressures.
Broken Cam. Could do it.
Something that would kill those two Cylinders yet allow the engine to turn over and still run.
One can only guess at this point.

It's interesting and I am also curious as to what happened.

They said they took a fuel sample and it looked okay. They wanted to drain the fuel tank and replace the plugs (for $822, which is almost my whole paycheck) and since i’d already changed them i asked to just drain the tank instead. hopefully they’ll find something in there.

I’ll post an update whenever i know something new

So if you have 2 cylinders with O compression why are they wanting to replace plugs
