Found part of the problem (pic) :D

I'm, not posting this to start an argument, but, in order for metal shavings from the cam lobe to get to the bearings, they would first have to fall into the oil pan, be sucked into the pickup pass through the oil pump.......which is all very possible.

Then, they would make their way to the oil filter and have to go through that before going to the bearings. Getting TO the oil filter is very possible for metal shavings that have fallen into the pan. Getting PAST the filter is I suppose possible, but not very probable. At all.

Wiping a cam lobe can produce particles small enough to pass through the filter and do damage. A filter is not a 100% catch-all for particles in the oil, especially the cheaper crap you get at the big name parts stores.

He can roll the dice and maybe be ok without pulling it and cleaning it, but I really doubt it. Given what his future plans are, in my opinion he should just go ahead and replace it with the 360 now. Running that 318 without a thorough cleaning and checking may ruin it.

Just my .02
