stock 596heads - and to make things worse - I called hughes and described the problem and was told "nothing i was saying raised red flags"?? So I keep going through the lash setup and noticed on the driver side two of the hold downs loose!! With nuts torqued to 16 lbs !! What the heck ! ! &@$*#&$!!!!!!
Easy fix but it happened to you too ? That not seen could have spelled disaster. One of the loose shaft mounts was over the oiling hole. I didn't bring it up on my last post because I didn't want to sound like I'm complaining about hughes and thought it was probably a isolated incident.
