my 3vze engine sound bad
Well, this morning i went to the store and my engine started making this horrible noise...it sounds like someone put marles inside the engine or tranny....so when i got home, i got under my 4runner and check everything to make sure nothing was loose. The noise comes and goes, it goes from nothing to very loud....and when i touch the oil pan, i fell a lot of vidration like if something inside is hitting it...any ideas on what should I start looking at?...ps, my 4runner is a 95 3vze 5 spd with 206k miles...and like 6 months ago, i change the clutch and forgot to change the pilot bearing. Thank you everyone.

Drain your oil through a screen. You might have left something loose in your clutch instal ( maybe pressure plate bolt). Same with your trans oil.

Well when does the noise go away and come back? Is it just random or RPM related? Cold or hot engine? Clutch in or out? Could be something as simple as an exhaust rattle, try hitting the exhaust and see if it makes the noise, pay attention to the cat as well as they can rattle if the cat is coming apart.

That does not sound good at all. It does seem to change a bit with RPMs?
Oil level and quality looks good?
Other fluids?
Spark plugs are all in one piece? None loose?
No overheating prior to the sound appearing?
You might try pinpointing the general area of the noise with a mechanics stethoscope. Given the potential for continued mechanical damage, I sure would not run the RPMs up and would also try running it for a minimum amount of time during the diagnosis process.

you can feel a vibration in the oil pan while it was running?
you sure it's not just cuz the motor is running? lol
sounds like Pilot bearing...or it COULD possibly be something in the oil pan getting sloshed around?

Does your pil pressure gauge work?? It looks very low in your video and if your engine has poor oil pressure things can not be getting proper lubrication and wreak havic...

yep seems to me that the oil pressure gauge is not moving at all,mine at 3k rpms pass
1/2 gauge,and its obvious that engine is not getting oiled.
who knows ,rod bearings,camsahft bearings,main bearings,broken piston rings but did that guy ever check the oil pump??????

I have one of those in my truck right now...
Toyota makes at least three "standard" bearings, so it is going to be hard to get the right one even if that is still possible.
Mine is so bad that even after putting in a new bearing and checking the clearance, it was still outside the factory recommended max clearance...
Just have the engine rebuilt or buy a new/reman shortblock...
