| Distributor Noise I think. |
Subject: Distributor Noise I think. by marv02 on 2012/2/27 3:47:28 I been trying to find a tapping sound the motor has about 7000 miles on it CC Ultra Magnum pro Steel full roller arms. The rocker arms do make some noise but this not where the noise is coming from. I replaced the roller lifters with GM LS7 lifters, Put new push rods in it just in case checked push rod lengths there good and as long I had it apart. Tried many times to readjusting the valves preload. The distributor has a Composite gear on it for the Roller cam. Used the screwdriver to ear trying to find where the noise is coming from just can’t find it you can hear well thought the rear of the plenum area. At first I was thinking it was a intake valve slamming close but they say the LT4-hotcam should not make this noise because you can hear it in the rear plenum area. I was thinking it could be a bad bearing in the Distributor it’s pretty loud during cold start up after warms up it is still there but not bad but it is still there. Just makes me nervous knowing it is not right it has made this noise from day one when fired up this motor. I don’t have a spare Distributor to find out this is it I want to buy a new distributor but if I have to fork out the money might as well buy a nice one MSD Malory DUI which one to buy the car rev to 5500 RPM’s it is a street car. I would like the smaller distributor cap makes things easier to get to and work on would be a big plus. |
