Cold Engine Squeaking

[evansaero]

Trying to find the squeaking. If you watch the video it's the first part after start-up only when the car is cold. Like starting the car in the morning.

It goes away after the car warms up a little. 5 min drive or so and sound is gone.

I have taken off the belt and ran the engine. The noise is still there. It has been going on for the last couple months.

Today I replaced the spark plugs and the large-small o-rings on the tubes. Noise is still there.

Where else can I look or do

Try starting the engine with the oil cap removed.

I did that to. Still have the noise

Try unplugging your secondary air pump.

Try unplugging your secondary air pump.

I'll have to try that in the morning. The car has not been driven for about 6 hours and is still to warm to make the squeaking.

It only happens first thing in the morning. First start of the day and then will only come back after the car sits over night.

Thanks for the help

Started the car and had the squeaking. I unpluged the secondary air pump, tried the oil cap agian and I still have the noise.

I only two things that change the pitch or frequency is RPM's and pushing the Clutch in and out, but neither will make the squeaking no away.

Only after a good warm up will it go away and stay away until the next morning

have a look at the release bearing, perhaps the problem is situated in the clutch.

humm,Maybe-Is there a way to do that with out taking out the trans :huh:

I think I need to restate.

Cold car that has to sit over night.

Squeaking noise will increase with RPM's

If I let the car run for 10min and not drive it the noise is still there

If I sit and pump the clutch 20 times and run through the gears sitting in my driveway the squeaking is still there

If I drive around the block (not driving hard or load) the noise is gone with 3 min

The noise will not come back until the car sit over night.

So my guess is I must be the only p-car out there that has very had this problem :help:

Yes it is possible.Listen with a stethoscope, from the underside of the car, between the transmission and the engine bloc. succes.

And, why did you not give us that information to begin with? You can rule out the motor or anything else that has moving parts that do not rely on car movement or clutch operation. Is the noise louder or softer when the clutch is depressed? How about when the transmission is in neutral and the clutch is not depressed? Louder in gear or out?

Well, I have been trouble shooting and that is why some things had to be restated. I don't claim to be smart. It takes me awhile to think of doing things :oops: I myself thought it was the belt then the tenision rollers,and then the spark plug tube o-rings, then tried taking the belt off and running the engine. I have replaced everything and knew I needed to start looking elsewhere. I just thought it was the engine. Sorry about that but I do apprishate your help

Clutch out: Same as in video

Clutch IN: change in pitch (lower tone) to maybe softer

IN Gear: No Change

Out of Gear: No Change

I have a cold squeal as well. If it goes away while the oil cap is removed what is that an indication of?
