Engine Raattling...low power - Toyota Nation Forum : Toyota Car and Truck Forums

InTeReX · 07-16-2004, 12:53 PM

i started my car today and heard it rattling in the engine bay...after awhile at idle it stopped...but as soon as i pushed the throttle back down it started rattling. When i drove it down the driveway it had very little power at all..

anybody got any ideas???

and another thing...My dad had borrowed my car for about 2 months when he was down in florida on business. He claims he changed the oil, but i just got finished changing it and it was dirty as hell....GAH!....

do you think this could have anything to do with it?

Is the rattling coming from the top or bottom of the engine?

For your sake I hope its not the bottom, otherwise your looking at spun bearings.

If its from the top it could be a sticky lifter, worn valve shim, etc..

Does the rattling get louder the more you push on the gas?

i had the same problem. my was a bearing. whatever you do don't drive on it. it cost me a new engine

^ Yup. If its a spun bearing, it'll only get worst.

InTeReX · 07-17-2004, 01:22 AM

it doesn't get louder, it just gets faster as the rpms increase.
and it sounds to be coming from the top.

???

things that lead to spun bearings are such as....???

Maybe you just got a misfire, since you said you lost power. Check wires, plugs, etc.

terrynham · 07-17-2004, 07:14 AM

ive got a similar problem......whether or not it is the same as yours...i dont know

my sounds more like if you put a tiny little rock in a empty coke can and shake it around really fast

, thats the noise i hear

......but i only hear it at about 2000rpm

If you have a engine stethoscope you can pinpoint where the noise is coming from. Or just take off the vavle cover and have alook.

A sticky lifter or worn shim usually makes a ticking sound. Most ppl think its valve tick, but its not.

Spun bearings make a clunking sound.

Low oil level, going to long on oil changes, or the engine reving at high rpms for long periods of time.

i'm leaning towards spun bearings, if my dad is just lying to me and didn't change the oil while he was in florida.

cost of repair of spun bearings? estimated?

not really sure though...cause its not a clunking sound...its more of the rock in can be shaken kinda sound.....i'll take off the valve cover and have a looksy and check all my wires and whatnot...

thanks guys

This is pretty much the sound I get. It's like slapping a stick across a fence.
