Piston pin bad ?

Sent the rocker arms back to hughes last Friday and they already have shipped a new set back. Dave said he is not sure why I had the problem but took care of me regardless.

Great customer service !

He thinks I may have had the side clearances too tight . They recommend .015 total play per rocker arm pair between pedestals. That doesnt sound like enough to me ....I am sure I had at least that much. Would you think there would be more hot expansion than that with 2 rocker arms , spacers and shims ?
