The shiny metalic particles in the oil (particularly on your third oil change) is probably the bearings going away or the cam is being eaten. Either way, it's bad news for you, Chad.
Yes, a cam going flat will cause a lot of valve train noise.
If it were me, I would drop the pan and pull a couple rod caps and inspect the bearing surface to see if the bearings are being abraided. If they look good then move to the top end and inspect the cam and lifters for any wear (this can be a bit difficult since lobe wear can be hard to detect without measuring the lobes with a dial indicator) but you can get a feel for abnormal wear by the appearance of the lobe and the lifter foot. The lifter foot should be convex and have a slight roll on a completely flat surface.
There should be very little particulate metal after either an overhaul or cam replacement. And you certainly shouldn't be able to see the particles in the oil. The black appearance of the oil could just be the break-in lube being flushed out of the system. |
