Engine Crank Broke?!

If it breaks there, the engine can't move the car.

I have seen broken flywheels with the car still moveable.

Broken within a couple inches of where it bolts to the crank [flex area] of flywheel.

Also it made a lot of noise and sounded like the whole bottom end was falling out.
 
Their is no way to know what the transmission shop did with your car after the car got there.Mjght have been a line leaking fix that than a test drive and BOOM,just speculating.On my car I thought I had a header leak one day just driving a long 45mph got it home found it broke the crank.Hope all works out for you.
 
My guess is that Professor Plum did it in the parlor with the candlestick

But I have to sort of laugh at the chain of events.
They almost sound comedic.
Poor wife tries to do nice - takes car.
Now - I can't relate since, being non-married, no one drives my cars - and no one touches them - even with a micro fiber towel.
But we've eliminated the detail shop.
And we think we've eliminated the wife. - Well, not officially, since I think she is still quite alive - unless this really does turn into a broken crank. :D
So the car gets towed.
Towed - home - of course - right?
Nope - to "some transmission shop" - which is always the knee slapper.
I pray it is not - "Beep Beep MCO"?
Now Professor Plum at the Transmission shop - who of course knows all about "deese der Grand Montes" - drops the inspection cover and diagnoses you for a broken crank.
Me - I do believe I'd like my car in my garage so I could see for myself where all that reddish fluid is coming from.
It'll probably turn out to be a loose trans cooler line. And the trans shops guy's head was the one wobbling.

But ain't it always somethin'?

I only changed radio stations and I blew a head gasket?
Why did that happen?
And - is it related? :rolleyes:
 
If you broke the crank I would assume there would be a catastrophic shutdown in seconds. Now while I agree with everyone above, don't hate on Mr. Tranny guy for attempting to be the hero and diagnose a car he does not have the knowledge to truly know what is going on (probably still thinks its a V8).
I broke my crank just casually driving 50mph to the track, I heard a loud ticking noise, picked up large amounts of detonation on the SM and then it locked up. There is almost NO WAY! That car would be running with a broken crank. I would have to assume you have an issue between the rear cap and the bellhousing, causing the flywheel to "wobble" (which can also be deceiving, mine looks like it wobbles a tiny bit as well and everything is fine).
 
Believe it or not I had one that still ran with a broke crank. :eek: It was crazy. One of the rod journals was cracked on a angle. It was banging but still ran.

I've also pulled cranks that were cracked all over the place but not yet all the way through.

Stock cranks are time bombs and when they crack in half you can bet that they were already on there way.;)

I to have witnessed one runny with a broken crank wasnt smooth by any means it hammered pretty good.

With a broken crank if you try to start it the front accessories will not turn, easy to diagnose.
 
Lmao. "My crank just broke and its still running, no big deal right?" Can I still turn up the boost please???
 
A lot of years ago, I broke the stock crank in my car. Yes, it would start & run. Sounded like a diesel, but it would run. Pulled it apart, & found the crank broke in 2 pieces & a main cap broke. :( I was able to use the block again.
 
I'd get a second opinion too. Although it is rare, a crank can be in two pieces and the engine will still run. I had an escort motor where the crank was in two pieces but the two sides couldn't separate because they were held in contact by main bearings. It only made a small knocking sound and I miraculously caught it before catastrophic failure.

As for your lady, in the 1800s there were cases where cast iron bridge would hold long enough for a fully loaded train to cross, only to fail later in the day when the same train, now unloaded, went back over (Google Wootton Bridge Failure). The solution in the end was to build steel bridges. Sounds like she was just unlucky!
