Engine rattle in new Gladiator - better video

[Flash 2004]

Its unlikely the two are related, it apparently hydrolocked on a mixture of water and oil. The initial fail you see on video one was probably caused by the PCV system being overwhelmed by oil and feeding into the intake manifold creating enough pressure to cause a failure of the head gasket and the mix of steam and oil smoke seen in subsequent videos. When it cleared and I tried another climb was when it all went haywire. Important to note it had just had its 12,000km service 3 days and about 100km before this incident and was overfilled by about an inch on the dipstick. I have a video of that cold engine check showing the overfilled level but the service agent said it had the right quantity of oil in it, so I drove it.

I almost had this situation in my last truck when the engine was replaced and tech installed 6 litres to an already filled crankcase that had 6 litres in it. So I had to do a 1600 km road trip as soon as I picked it up and when I got back home and performed the oil change, 12 litres came out! What a mess, oil all through the intake tube and spilling into the upper intake plenum. Hadn’t yet hit the cylinders but was told it could have locked up real bad. Maybe we don’t call it hydrolock but oil spilling into the cylinders and locking up must have a name.

I was only highway driving mostly and 50 kms of forestry road and engine got hot enough for me to feel something wasn’t quite right and I had to call the service manager as I was travelling down the highway. I never saw any smoke and was definitely not doing any angles as you had your truck doing but ya, over filled by an inch… we see what that did for you.

No telling where my oil line was on the stick with 12 litres in there.

Not possible.
The PCV is up high on the engine. If you had twice as much oil in it as belongs, maybe - but you'd have to be going up almost 90 degrees to get that much oil up to the valve cover area.
It's literally not physically possible to pull that much oil though the PCV with a normal oil fill at even pretty extreme angles. It would take a climb so crazy........ I mean, standing almost on end. These things climb crazy angles all the time without issue.
No PCV failure would cause it. Not a full lock. Otherwise, we'd be seeing this left and right.
