All of a sudden while driving I start hearing a ticking valve train (assumed) noise. Also the exhaust sound changed to (another assumed) sound of not firing on all cylinders.
Got it to my mechanic and in about 15 minutes he found the problem...a broken bolt that secures the rocker shaft on the driver side. (Aluminum heads, roller rockers). There were also some broken helicoil threads coming out with it. Apparently that is a standard procedure to utilize helicoils in this application into the aluminum heads...?
