hey guys need your help. i got a 2001 chevy blazer 4x4 model. heres the problem, when im in first and second gear i hear a rattling noise coming from the enigne anyway i figure it out its coming from the dizzy (distributor) it only happens when i rev the car to 2000-3000 rpm . When i was in neutral and rev the car i feel a vibration from the dizzy. do you know what cause this?? will i need to replace a new one. I live here in australia and getting parts its not easy.
please help me out

 

You'll want to pull the distributor and check the shaft for play as well as the lower gear for wear. Sounds like the upper bushing has gone bad.

If you need to replace it, follow the EDI Engine Timing thread in the Tech Article (DIY) section closely.

 

Thanks for that will check it out and let you know how it goes. Btw is it still drivable?? What are the chances if I keep driving?

 

Could leave you stranded if something decides to go really wrong inside. It'll work until it doesn't want to anymore.

 

Ok Thanks will Sus it out and let you know
