Default Low oil pressure and HORRID sound - Video

So I think my oil pump went out on me, I noticed a steady tick that went with the exhaust note.

Video from last night, don't laugh, I have a speech impediment



any thoughts?

Sorry to break the news but your engine is toast! Mine sounds like yours at idle but doesn't knock that hard when give it gas. I am pretty sure mine is a spun rod. I'm prob going with a lq9 budget build.

*side note: I have never witnessed that many trouble lights on at once!!!!

I wouldn't start that engine again. Next time you do, you might waste your block. Time for a teardown.

Sounds like a spun rod bearing to me. Can't believe it's not running poorly though, when mine spun it didn't want to run hardly at all. Although I had about 3 spun bearing and 2 of those were stacked.

You can do a cheap rebuild it's just a lot of labor.

Holy mother of god, I cringed when you revved it. That motor is definitely done. I'm not guru and couldn't pinpoint the noise like these guys, but a spun rod definitely sounds logical. That baby is beating up that crank!

Bearing for sure. Simple rebuild with light machine work is all that is needed.

Got to 1:03 thinking hmmm, doesn't seem too bad, but when you rev'd it was definitely mega-bad. Sounds like rod(s), new motor time or rebuild.

Bearing issue 100%. Rod bearing most likely. And a simple rebuild is a maybe. Depends on how bad it is beating the crank journal up. Good luck. Start it only to move it and try not to rev it anymore.

And pull the valvecovers and check for a broken spring or rocker arm.

I'm not saying it's not bottom end problems, but start at least on the top end. Everyone's diagnosing the car based off an internet video. I had a broken valvespring that sounded like that, but again, I listened to the video on a laptop.

It takes 2 minutes to pull a valvecover.

And for the record, I AM SANTA CLAUSE *****'******.
