1983 Delta 88 Oldsmobile engine 307 v 8 engine area squealing have taken off all belts so I know it not the alternator power steering or fan. It squeal when first crank up and sometimes It doesn't but usually always when it gets warmed up and sometimes it goes away after it warms up. Squealing sound get higher when reaved up. Had heard stories how sometimes being starter not disingaging and starter is about five years old and it does squeal when it just idiling and driving any help would be appreciated thank you.

 

Sounds unusual... Do you have a short video that you post just so we can hear it?

 

could be a component early bearing failure...alternator, ps

 

with the belts removed?
that kind of rules out PS and WP

Got oil in the engine?
Sounds like maybe a vacuum leak.

Use a pc of hose as a stethoscope when the noise is present, to locate the source. Listen in the oil fill, around the intake gaskets and fittings, etc.

 

Water pump?

 

Removed...not replaced...ok

 

Is it really a squeal, or more of a whistle? Whistle would indicate vacuum leak. A true squeal can't be good.

 

i can get a video of it 2moro and post it

 

heres a few vids see if you make anything out of them

 

ok here the vids on youtube couldnt get them loaded here http://www.youtube.com/watch?v=_nf_a...ature=youtu.be

 

That's the noise mine made when I spun the bearing

 

Ouch - that shriek was hard to listen to!
And it does this with all belts removed?

Does it come from the disty by any chance?

 

did it do it all the time are just some times if you spun a bearing and naw i dont think so just reaplaced about year bck but has been siting up

 

Look for things rubbing: bent flexplate, something against the balancer, that kind of thing.

If nothing, then, yeah, a spun bearing goes up the list a few notches.

Is there any way to localize it? Like, by listening through a pipe?

"Use a pc of hose as a stethoscope when the noise is present, to locate the source. Listen in the oil fill, around the intake gaskets and fittings, etc."

Sounds like a diesel
or a gas engine with a bad main bearing.
I foresee engine removal in your future.... and mine.

I saw a belt still turning, so maybe the AC is the source, esp. if its clutch is dying.

 

the knocking in the video is the engine mounts i hope so dont listin to that and yea i put the belts back on but it make the same sound with r without and its a gas 307 v8 and its been seting up but if it was the bearings why would the sound only happen sometimes? and i listin 2moro try key point but its so dang loud lol if it is the bearing could someone list a complete list of parts i need and if i have take the engine out im doing a rebuild but if i could just take the oil pan off and do this i do that for now any help whats so ever anything at all plz thanks

 

Ya, i seen a belt turning in the video,if its the same sounding without any belts ,i say lower end IE bearing seizing-ed.

 

Mine did that.....was rod bearings!

 

Do you have any oil pressure? Sounds like dry bearings to me. And it sounds ready for major failure.

 

i also saw the a/c comp turning...sound like thats at least one of your problems

 

send a vid if you can without the belt

 

im not gonna make a vid without its the same with r without its been doing it for bout 2 years now but has set up all but 3 months and cranking it here and there you know so i think im gonna change oil clean everything up and how can i see if i have oil pressure and after that dont work gonna pull it and body know of a good motor stand lol
