Did I just Seize my motor!?

[shorepig]

85’ westy automatic.

I just did a hill climb, in my auto westy in 2nd gear and forgot to put van back into “drive” before descending. I descended at about 100 km/hr. So yes, I over revved the engine and didn’t realize until the bottom of the hill when I heard the engine revving high and then there was a brief moment of a valve-y / pinging sound that lasted for a brief moment. At this moment I realized it was in 2nd and threw it in drive. Then engine stalled and I drifted to a stop. When I attempt to restart the engine doesn’t even turn over . I have 12v at my starter battery.
It just sounds like there is binding or the starter cannot turn.

What do the gurus of thesamba think has happened.

100km/hr (62mph) in 2nd....
I wonder how many RPM that is?
My gut feel is that it's (high but) not too high.
Some automatic trans feller will know better than I.

But the noise could have dropped a valve.
Which could stuck the engine...

Can you turn the engine by pulling on the drive belts?
Or with a wrench on the alternator pulley?

I haven’t tried yet but will when I get the van home. Just waiting for a tow truck. Re rpm’s I know I rev at 3800 rpm when cruising at 100 km/h on a flat rd.

kamz table shows vanagon with AT and 25.6" tires running at 3,221 at 60 mph. The gear ratio for 3rd is 1.00 and the ratio for 2nd is 1.5 so it would run at 4,831 at 60 mph in 2nd, well below redline of 5,400. At 70 mph you'd be flirting with redline depending on your setup.

Bigger tires let the engine turn slower.
25.6 / 26.9 = .95 (5% slower)

Using Jims & Kamz numbers…..
.95 x 4831 RPM = 4600 RPM,
~the hairy edge~ of acceptable, but not in the red.

I don’t think your engine problem was caused (specifically) by that 2nd gear event.

first off, see if you can rotate the engine, backwards a little.

l have an up and coming subaru conversion, because of a lock up, it turned out to be the rockers on cylinder #4.
it would go round to a stop, and then back the other way, until a stop, my initial thoughts were it was a bolt had come out of the torque converter, it turned out is was the valves has hit the piston.
it was the push my customer needed to go for a conversion.

Oil and coolant level OK when you were doing your downhill run? No indicator of the coolant temp gauge or red led pegged? Oil light and oil buzzer didn't go off?

More than likely valve is stuck open or dropped.

As others have mentioned try turning the motor by hand to see if there's a hard mechanical stop. Might need to get one of those inspection cameras to drop down in a spark plug hole to see if you've got a valve and piston that decided to have a romantic rendezvous.

quite possibly that while below redline a rocker could have still popped off a pushrod or sumsuch.
I do agree to pop the valve covers 1st..

Valve float and valve hit the piston. I don’t think throwing it into drive is related. The noise you heard that alerted you to the fact you had left it in second was the sound of a mechanical failure.

“Hill Climb” is that some sort of competition? Trying to understand the logic of manually downshifting an automatic going up hill. Granted I am a flat lander. Sounds internal to me.

There are hills here that I have to manually shift my automatic to second to keep momentum going uphill.

Downhill downshifting to second would be for engine braking purposes.

My native shift pattern from 2nd to 3rd doesn't even hit the "power band" RPMs.. I nearly always shift to 2 at a stop sign, and push to 3 when I hit 50 or so mph.

So it’s semi-automatic.
