ragnbull Report post Posted September 14, 2009 Over the past 3 years I have broken 2 rotors on the distributor. Its been the upper arm both times. Has anyone else had this problem? Someone told me that it might be a out of balanced dist. Does this sound right? Is this a common problem with these rotors?

ragnbull Report post Posted September 14, 2009 The last 2 times I've used the ones you buy from Napa. I have a feeling that could be my problem. Quote Share this post Link to post Share on other sites More sharing options...
13MM Report post Posted September 14, 2009 Same here NAPA one. Maybe this was one reason jags engines had bad rap? Quote Share this post Link to post Share on other sites More sharing options...

DKDiablo Report post Posted July 11, 2010 I had the Napa rotor break as well, I keep spare rotor and cap in the Diablo at all times now. Which cylinder bank did you lose when this happend? My 1993 Diablo lost the left bank last weekend, and I had to leave it far from home... looking forward to get the chance to go thorugh the car soon... I have the rotor under suspision... I found this from the Jaguar cars: http://www.jag-lovers.org/xj-s/book/Marelli_pix.html Seems as a common problem. Quote Share this post Link to post Share on other sites More sharing options...

huntnphool Report post Posted September 21, 2010 No idea if they are different manufacturers but I have had good luck with the rotor from Autozone, been using it for over a year with no issues. Quote Share this post Link to post Share on other sites More sharing options...
