Thread: Squealing noise from engine!! Need Help!!

Ok I think we are getting really close!! I bought an o-ring at lunch and installed it, then ran it for about 25 min and shut it off. It didn't make a sound and I took off the vent cap and these was no negative pressure inside the engine. After I got home at 5, I ran it for 45 min and there was no more squealing!! Only thing now is that when I rev it up the rpms drop really low and then it dies for some reason. Thanks for all the help I really appreciate it!!

And all of this is while the car is sitting in the driveway, I haven't driven it in about a week.

Oh and I did disconnect and reconnect the battery in an attempt the disable the check engine light before I ran it for 45 min at 5 o clock.
