A couple of months ago, I wrote in about a strange = rattling noise from the engine...which I thought was exhaust or maybe just a = dirty engine. I replaced just about all the exhaust system and the noise = still existed. Then I thought I'd try some CD-2 oil detergent. In = a short time, the noise disappeared....or so I thought. The noise = reappeared again last month. So, last Monday, I took the time (once again) to investigate. The "noise" seemed to be coming from the new = German muffler. So, I removed it and = checked....odd....nothing loose. so I reinstalled to keep tracing. I finally tracked it down to the = head on cyl #1. Compression tests all check OK. Then I removed the = valve cover and started the motor and the noise got louder. It = was coming directly from the rocker arms. I removed the rocker arm assy. only to find all of the adjusters tips flattened out. = Also the clip that holds the spring and flat washer was "eating" into = the flat washer and the rocker arm has a little play. I twisted the washer so that the clips rides in a different = position....then attempted to re-install the rocker arm assy. I had = a hell of a time getting the pushrods so seat properly and I = noticed a little damage on intake pushrod end from the lifter side. I'm = thing that the PO may have not installed the pushrods correctly in the = first place and that all this crap is the = "aftermath".
