So i was just driving going 40-60kph when out of nowhere i hear a loud BANG. pulled over immediately just to see the pulley literally rolling down the road beside me. The car still ran, lost power steering and alternator. grabbed the pulley and went home immediately. My guess was the bolt backed out but how.

Next morning i went to inspect the damage and found i tiny chip on where the woodruff key sits. Made a video and the scratch noise you hear is the timing belt guide cover loose. I just hope nothing internal was catastrophically damaged. i’m gonna check the timing soon. Is my crank still good? i’ve heard about people using JB weld to fix it.

You will need to pull the Timing covers off, Belt/etc.. and get a good view of the Crank's 'stub'/keyway, etc..
Impossible to tell anything from that picture, regarding the Crank.
The pulley, is certainly a paperweight now, get a new one.
And when you order one, order a new Key as well.

update: the key is actually broken halfway and the chip is just at the edge of the crank, how am i gonna pull that thing out?

Once the Timing covers, Belt, and timing pulley are removed:
You should be able to pull the remaining part of the key out of the Keyway (remember to pull 'Up', i.e. Perpendicularly away from the Crank stub).
The best tool I've found to use when doing this, is a good pair of cutting Dikes. Sounds crazy, but in most cases, you don't have a lot of material to grab ahold of, even with a Key that is not broken.
With that said, Good luck!
Also, you want to avoid touching the Keyway with your grabbing-tool of choice, for obvious reasons, you want to preserve the Keyway as much as possible.
A new Key and Pulley, Easy.
Replacing the Crank because Keyway is borked, NOT Easy.

If the keyway on the crank snout is jack up a little as it appears to be, you should check out DrTalon123's post on here of repairing something like this on car. He did it, and it held up under some very extreme conditions. So it is possible to not have to replace the crank even if it is janked up

Can I drive a little bit just to get the car to the shop as it stands or am i risking the engine?

is the key in there at all or am i just speculating, if it’s not then i can just put in a new one, fix a new balancer and be done with it

how you gonna charge the battery?

dont see a key.

order a new crank pulley bolt and a torque wrench

i need to drive it to the shop which is literally 100 meters away. as for the key i think it’s not in there at all.

what do u think, is it bad or will i be able to get away with that tiny chip at the edge of the crank

 

[slo_eg8]

order a new crank pulley, key, bolt, and torque wrench....... go ahead and drive it, worst that can happen is the timing belt keeper falls off and the timing belt slips....its just a few valves

bruh what’s funny is that when this happened i had to drive back home which is like a 20 min drive…

I had a broken keyway on a crank for a Subaru, way before I was ever comfortable taking an engine apart.
I did a thing you should NEVER do.


I purchased a new pulley and a new crank bolt. I then added JB Weld to the surface of the crank snout. I then pressed the pulley in, added JB Weld to the keyway (filling it), and then tightened the bolt to the recommended torque setting. I then let the JB Weld cure for a whole weekend.

This lasted for a whole year, when I did an overhaul. I planned the overhaul as soon as I "fixed" the pulley. Never gave me a problem.

Of course, don't do this.

Edit: Let's be clear. No one here is liable for your actions. No matter what, anything you do with your car involves risks. Somethings sometimes works. Somethings NEVER work. You have to be the adult and choose what is best for you.

 

[slo_eg8]

do whatever you want, you asked questions, got answers....not gonna hold your hand for the whole process. whatever happens is on you. do you boo boo

 

[Soul Engineering]

If it's only 100 meters...........Push it.

But driving without a balancer is asking for destruction. I've had a crank pulley come off before. I loctite all of mine now, but yeah. I'm in agreeance. Buy a keyway, a new balancer, a bolt with washer, some red loctite, and torque that balancer down to spec.
