Staying tuned. One thing. Promise me that the next time you hear a loud bang under your hood, especially just after working on it, that you'll stop and inspect. :slap:

I actually did that. My brother was standing in front of the car on startup with the hood still open. He said it sounded like a loud metal clank. so i tried to replicate it after i inspected what i thought it was. I thought i heard it from the transmission area since i just put in the new clutch.
but yea gonna be an expensive lesson learned.

Teardown of engine but got stuck. While trying to remove timing cover a piece of sprocket fell out. I cannot for the life of me remove the timing chain cover. Something is stopping it from being removed. All bolts are off.

The sprocket has the half moon on it.

Anyone ever run into this issue? Or knows what i could do to remove the cover?

Did you pull the crank pulley spacer out?

Maybe try putting the crank pulley bolt back in and hold it while trying to work the cover loose.

I did try that. It wont budget. I grabbed it with channel locks. Its ruined now but i just want the timing cover to come off

Hold the bolt in? By hand? Or thread it in.

I was thinking thread it in and hold it clockwise with a wrench. If the pulley spacer is stuck in the cover it is probably bound on the oil pump which may or may not be in pieces at this point.

Yo youre the best! No sure if it was because of that directly but i turn the crank to where it felt smoother/looser to then and unthreaded the bolt left it on with the ratchet on it and it came off!

But yea it looks like my key way/woodruff key came pff with the crank shaft sprocket

Wish the circumstances where better. Glad you got it off though and thanks for sharing the pics.

I wonder how much runout the end of the crank has. Did the jolt just bust the key and sprocket or if the crank is actually bent.

Thanks for the help! I already accepted i broke the motor from stupidity. Not even the normal stupidity (driving like a hoon)

Runout? As in how long the front shaft is? It looks kinda long to me. Im assuming the jolt broke the keyway and a few teeth on the sprocket. I can turn the crankshaft all the way now so maybe its not bent? Its junk now always since turning it a few times, i heard a thud from the LH bank cylinder head i feel like since its pretty a little out of time its doing that.

Runout is essentially checking how much wobble is in a shaft.

It sounds like it’s not salvageable though. Such a bummer.

I wouldn't write it off quite yet. That hole is in the drive spocket. Looks promising, actually. I wouldn't be afraid of going at those burrs with a little bastard file.

say whaaaat?

So the hole might just be on this? (PN:13021AA240)

Don't you my hopes up! But so far I'm hoping there's no tiny metal/bearing bits. I didn't want to spend more money on stuff i already had like an oil cooler, timing chain cover. My wish is for the heads to be perfect. D=:happyanim:

Yeah. That's it. That's where the chunk of the sprocket came from. Could still go either way.
