Inquiry (采购产品): 1.6 roller tip rocker arms I purchaced a full set of your Elgin Pro Stock roller tip rockers for my 1972 350 Corvette. I installed them with the recommended adjustment of "0" lash with all cylinders at TDC and they clatter very loud. I have tried all adjustments and still cant get the noise to go away. Even though they perform well at higher speeds, there is an intolerable amount of clattering and tapping at idle and low to mid-range speeds. I was just wondering for some suggestions to solve the problem and i am very unhappy with these roller tip rocker arms. My car has hydraulic lifters and I have adjusted them in many ways and the rocker arms seem to be pushing the push rod against the cylinder head. I have spent many hours working on these rocker arms and am dissapointed because i cant get them to be quiet. Please contact me with any suggestions or information to help me with the adjustments. **** Hidden Message ***** Rich Tocci 214-502-2060 972-462-0459 Coppell75019 USA Company: Beck Title: supernintendant Phone: 972-462-0459 E-mail: richtocci@beckgroup.com **** Hidden Message ***** richtocci@beckgroup.com
