Currently I have FMS 1.6 pedestal rollers rockers. I just recently went in and tried to adjust my rockers because I was starting to develop a slight ticking, thought maybe one of the rockers came out of spec. I noticed that some of the rockers were getting grooved where the roller tip was rubbing on the inside of the rocker. Kinda looks like the rockers were shifting from side to side for some reason. I heard somewhere that roller rockers only have about a 40k miles life span, is this true?

Anyway, so now I'm looking into different rockers, and was considering Crane 1.7's. Would this be an OK decision, with my E-cam and other such mods in my sig? Would I notice any difference at all?

Thanks, Craig

with 1.7rr's and that e-cam you will be right at the 220@.050 limit for valve to piston clearance...so you might want to check that out...

Not sure, but it sound like your rockers are side loading a bit. Do you have guide plates on the pushrods? I think Isky makes a set of adjustable guide plates that may help cure your problem.

Nope, no guide plates.
