So i was driving home today from pt in the morning and i noticed my car making a funny noise....Finished driving it home and parked it but then when i went to go back outside and restart it... It started making a LOUD chirping noise, seems to be coming from the flywheel but it is so loud that it encases the whole engine bay and not sure where it is coming from. I then turned it off and had my roommate see if he could hear it and when i went to start it the starter did made that slow "i dont want to start for you" noise. When it finally started up it made the same "chirping" noise. Was closer in time together when it was in park or neutral also...

Any Ideas?

455 Ci/th400 combo

 

Cracked flexplate near the crank??

Does the trans fluid still look good?

 

starter gear not retracting and a bearing in the starter squawking?

 

Slow crank (like a real tight engine) and a loud chirp, sounds like a spun bearing.

I did not want to hear that one.... Just got done rebuilding the damn thing....

Looked fine to me same with the fluid

Time to pull the starter... always start with the cheapest problem right?

 

I seen this on two car's one a 70 gto judge and other a 351 Windsor that was a commercial air compressor . The gto squealed like hell and the widsor locked up thought we blew it up started to tear it down and found the problem
Good luck.

 

distributor gear bottoming out in the block...thats what happened when mine was chirping..needed a gasket to bring it up a bit.

Here is the video of it running.

The weird thing is I have been daily driving the car for almost a month now and today is the first time i heard the problem...

 

OUCh - that squalling hurt my ears in that vid!
If coming from the fron tof the engine, pull all the drive belts and run under a minute or two to rule out accessories.
Hope it is not the bearings!!!

 

yeah it hurts my ears and my heart and maybe my bank book ><. Which sucks cause now both of my cars are in no driving condition....

 

There was another guy with a sound similar to that and his ended up being bad bearingS. It was thought it might have been something with the water pump or the cam button on the timing cover, but it was rod bearings.

I hope yours is not so bad, but man that sounds AWFUL!

 

Ouch. I hope its not, but it sure sounds like it.

 

Sicky,

I sure hope your engine builder knew about Olds engines. That doesn't sound good to me.

 

That really sounds like a bearing to me. If you just had the motor rebuilt, your engine builder should fix itatno charge to you

look up my vid on YouTube titled "307 with blown motor" I had a knock, then spin a bearing, then I shot the vid. I would post it up for you, nut I'm on my cell phone right now posting this

good luck

 

Here you go Redog.

Well... The guy who rebuilt the engine was me and a buddy in my garage... So can't ask for a free fix on that. Just seems weird cause I almost put 1k on the motor and you would think it wolff have happened before that? But the guy who machined it def did. He does everyones motor in the club

 

Thee funny thing is I am not heating a knock. Just that damn squealing noise.

 

It may be the cellphone vid sound quality, but something sounds like it's knocking.

Are you seeing anything in the oil? Has it been changed since the rebuild and did you check to see if there was any metal in the filter?

Any align boring done? Crank turning? How did you set your bearing clearances?

Drop the flywheel cover and see if there's anything stupid going on in there as that's the easiest thing to check. A transmission bushing will raise hell like that too.

You DID put the galley plug with the hole in it where it could lube the timing chain, right? The other one at the back shouldn't affect anything as all it does is keep enough fresh oil flowing thru the galley to avoid sludging, but nothing is above suspicion.

Good luck, flyboy friend. I know you hate to hear all this.

 

Just to be sure i took off the belts to the alternator and still making that noise. Funny thing is when i rev it the noise almost seems to go away.... Is that another sign of a spun bearing? But i still dont hear any knocking.... Going to drop the starter next and see if its sticking i guess

 

Drop the into a clean pan. Once its in the pan, stick a finger in and give it a stir. You'll see it if its a bearing.

Yes changed the oil but i havent drained it to see yet due to troubleshooting the easy parts first

Du whu? Yes crank is turning cause the motor runs? and to the 3rd question i repeat du whu?

Going to check that right now and get back to you, but how do i check a transmission bushing?

As far as i know everything was done correctly. The guys i did this with have rebuilt many olds engines

Thanks for the input guys and i would just like to remind you i am not TOO mechanically inclined here but trying my best

 

drop what into a clean pan?

 

Yikes I thought my motor made funny noises, that sounds like a poodle got stuck under your car

 

Sorry brain works faster than the fingers. Drop the oil.

 

Not good to hear. I don't care how much you trust your machine shop. Always plastigage your bottom end. Everyone can have an off day. I've even had mis-boxed bearings .040 in a .030 box(1 out of 8 packages)

 

I THINK I FOUND IT!!!!! pics posted soon on what you guys think... But i think somehow my flywheel is rubbing against the transmission housing!!!!

 

clutch disk on backwards... springs are hitting the flywheel bolts

 

Do Automatics have a clutch disk also? And wouldnt they be doing that from right when i first started running it?

 

Loose flywheel bolts? loose torque converter bolts should clunk and rattle

 

Hopefully just a broken flexplate.

 

Seems like it is something with the distributor. The bolt that holds it down was loose, now just trying to pinpoint what it might be on it. talking to a buddy to see if i can fix it. might be right though 442Scotty

 

Can i get more explanation on this one please? Was talking to a guy and he said that made no sense to him so can i get more explanation on this one please?

 

I have my fingers crossed for an easy fix...

 

I purchased my distributor through DUI...They did an awesome job setting it up but it screeched as soon as it was installed...I took it out and found that the casting was too long causing it to bottom out in the block so I made up a nylon gasket to go between the unit and the intake which was edelbrock. It raised the unit up just enough and no more screeching. I could have ground the bottom of the gear I suppose to take some meat off and do it that way.

 

Doesnt seem to be the distributor. no excess wear in the distributor or funkiness. Also pulled up the valve cover jsut to see and nothing looked bad to me... We are thinking it might be the Cam or something with that, reason for this it almost sounds to be in interval and it also seems to be every other rotation it makes that noise...

 

i hear some knocking but it could be bad video quality try to but a cheap mechanics stethescope or loud screwdriver to isolate the sound in the bottom end you put the screwdriver to the block and an ear on one end it works beleive it or not hope its something simple

 

Did you pull the converter loose from the flywheel and push it into the trans and start it to see if the noise changes? That noise really sounds external from the video, and I would suspect the cause to be in that area.

 

will have to try that but the wierd thing is that it "stalls" as soon as i stop giving it gas now...

 

Ouch. That could mean its getting ready to lock up tight. Have you dumped the oil yet? If not, I would highly recommend doing that before you start it anymore. If it is a spun bearing, your only causing more damage by starting it. My .02

 

havent dropped the oil yet. will do that this week when i got the time
and only starting it on rare occasions. We might think it has to do with a cam bearing or something...
