Camshaft cover defect causing rocker-arm breakage (P1302)?
Badnis on exiges.com—in a thread documenting rocker-arm breakage and P1302 codes—suggested that the high-lift intake cams may be getting improper distribution of motor oil from the overhead oil feeds in the camshaft cover. He backed that up with a photo of a test conducted in his shop where fluid was circulated through the camshaft cover system, which appeared to show less-than-desirable flows.
Well, I thought this was plausible, and—along with my buddy Nick (ZTEC)—felt it would be worth trying to repeat Badnis’ experiment. We first tried to avoid any mess by trying a quick CSI-type setup (sorry, no lasers!) to see if there might be anything to this. The first shot is Badnis’, from exiges.com, the next two are our dry tests. The results warranted further investigation.
