87 non-turbo needs suggestions
 

I have an 87 supra and recently been getting a loud howling sound from engine. I can not figure out what the problem is,,, it howels when idling and when sitting in park. Thought it may be ac pulley, tightened it first then removed ac belt but that did nothing. any suggestions?

Take a video of the car idling and upload it so we can hear this sound.

I will post a video soon
