Title: JPM Rocker Arms problems Post by: Mkracing on July 14, 2014, 17:44:07 pm Hey Guys, hope you can help me out of this one.
I have an 2387 cc street engine, with MS230 heads, and the 5 bolt JPM rocker arms. The engine as being rebuilt, with new cylinders, and new JPM raptor cam. However the problems is, that the rockerarms breaks the pieces, that holds the rocker arms?? I/we can not figure out what the problem is. This is the 4 times it breakes, and it is different ones. It seems that, the metal is to hard, and cracks!?? Any help will be appreciate... both on this topic or on PM Morten Title: Re: JPM Rocker Arms problems Post by: Mkracing on July 14, 2014, 17:47:48 pm IMAG0072.jpg
