I just got my new (rebuilt) 306 going and i hear a squeaking noise which sounds like it is right under the intake. I took off the drive belt, valve covers and ran the motor, squeak is still there. pushing in the clutch does not help either. If I stand directly over the front of car i hear the squeak, kinda in the lifter valley. I cannot pin point this noise. I am wondering if possible that the push rods are rubbing the guide plates?? maybe i should back the throw out bearing all the way off the clutch?? Any input appreicated.. Thanks!!

Yes,
any pressure on the clutch does not make a difference. It almost sounds like a bad alt. or water pump, but i tried no belt.. Can a throw out bearing make noise all the time pressed or not????

it usually will go away when pressure is put on it. did you grease the throwout bearing before you put it on?

I figured it out.. I remover the lower intake and found when i turn the motor over i hear the squeak. It was the lifter rubbing on the u shaped hold down.. I am going to buy new lifters as the ones i had were used. I also noticed that the plunger part some of the lifters was compressed by the pushrod . Is this normal? or are some of the lifters collapsed? thanks for the input...

Click to expand...

6LBS? Big cams cause low vacuum. Doubt you have a HUGE cam though. Maybe check timing and for leaks?
