garyneedsz Posted November 22, 2009 Share Posted November 22, 2009 hello all. my 77 280 has been giving me problems ever since i swapped in a zx dizzy (e12-80). the car idles perfectly but there is this strange noise. i used a stethescope to pin point the noise. it is coming from the oil pump/oil shaft/ or the dizzy itself. Where it makes the most noise is when i point it at the timing cover right above the oil pump. i used the 280 shaft and pump. is there anyone who can give me advice to what is causing this noise? thanks Quote Link to comment Share on other sites More sharing options...

Cheesecakepiebar Posted November 23, 2009 Share Posted November 23, 2009 "strange noise" doesn't help much in diagnosing problems. Is there any way you can post a video of the noise on youtube? Quote Link to comment Share on other sites More sharing options...
hoov100 Posted November 23, 2009 Share Posted November 23, 2009 Did you put a little grease on the gear for the dizzy shaft? Quote Link to comment Share on other sites More sharing options...
garyneedsz Posted November 25, 2009 Author Share Posted November 25, 2009 thanks hoov. popped out the shaft, put some valvoline grease on it, n no more noise. Quote Link to comment Share on other sites More sharing options...
garyneedsz Posted November 30, 2009 Author Share Posted November 30, 2009 hrrm. the noise is still persistent even with the grease. should i swap the oil pump to a zx just in case? the stethescope is pointing the noise to directly above the oil pump Quote Link to comment Share on other sites More sharing options...

garyneedsz Posted December 2, 2009 Author Share Posted December 2, 2009 In respects to this diagram, what piece would it be? http://atlanticz.ca/zclub/techtips/distributorrebuild/distributor%2079-81zx.gif i also forgot to mention that i switched from 5w-30 to 10w-40 before the dizzy swap. i am unsure of how many miles were on the block before i ran it. could this be the issue as well?

garyneedsz Posted February 17, 2010 Author Share Posted February 17, 2010 It'll be your dizzy bearing for sure. what is the "dizzy bearing" exactly? part number? drawing? diagram? thanks Quote Link to comment Share on other sites More sharing options...
hoov100 Posted February 17, 2010 Share Posted February 17, 2010 what is the "dizzy bearing" exactly? part number? drawing? diagram? thanks the sealed bearings inside your dizzy. that little shaft that connects the dizzy shaft to the rotor in the dizzy is supported by a sealed bearing.

Jeff260z Posted February 18, 2010 Share Posted February 18, 2010 Did you inspect the breaker plate assembly before you installed the dizzy? The breaker plate bearing holders tend to deteriorate and crack. May cause the noise you are hearing... Quote Link to comment Share on other sites More sharing options...
