Sounds like spun bearing please help!!
I have a 1998 Blazer I just bought off my brother. It has 104k miles in good shape never gave my brother any problems. Oil pressure has been good, runs great other than a misfire. I cleaned MAF, ran some seafom made it alittle better. Decided to changed cap and rotor and both looked worn. After replacing started right felt much better I was reving it to around 2500 rpm and then back to idle. After a few mins of running all the sudden I heard a small noise and then a sound like a really bad rod knock and lots of shaking in engine. Shut it off, started back up ran fine for a few seconds then really bad clunking sound in engine and shaking. All the wires are correct. Oil pressure still good. Any thoughts? I am praying it’s not a spun bearing.

can’t compression test running to rough afraid of spun bearing it may further damage engine might be doing a rebuild now. I have never had an engine go from running great to out of no where having a catastrophic failure. No oil pressure drop nothing. Would a broken flexplate bolt cause this kind of shaking?

It’s not th engine I had some time today started it up it didn’t make that sound then after a couple minutes started making it. It’s coming from the transmission. It’s making some kind of sound from the bell housing area that get worse if I rev it in park but not coming from engine. It’s loud enough at first that made me think it but engine is sounding fine. The sound from the trans is loud then stops and loud again.
