Re: Distributor Cap

I had the same problem with my cap and rotor after ruling out the housing and shaft runout. Found the problem was the rotor itself the fit that goes over the shaft was oversize the rotor would rock on the shaft and hit the posts on the cap. After checking several old used rotors on the shaft found the NEW rotor hole was larger and allowed to much movement. Guess we all assume the new parts we purchase are of the same quality standards as the orignal name brand OEM parts. Looked on Ebay found a orignal Delco still sealed in paper and metal box.
