I'm having a very odd problem one a newly rebuild engine . I have about 2-3 per side rocker arm plastic retainers that are showing lots of rapid wear on one side of the retainer(1/16"-1/8"). I noticed the problem 2 weeks ago when I went to replaced the valve cover gaskets . I replaced the worn retainers . Today I pulled the valve covers off again and found it was happening again . I am using Jason Crammers rocker shaft supports . Could the supports be putting some kind of "side load" on the rocker arm thus causing the retainer to wear faster? This has me stumped . please any help is VERY welcomed .
