Got a question on King bearings ?
We did two blown Alky 540 BBC engines about 3 years ago.
Fired the first one up on the dyno, using Brad Penn 50wt.
Did a little warm up, ran the valves, check things out, checked the oil filter, things were good !
After the 3rd real pull, checked the filter again, found "shavings" in the filter. They were soft , aluminum colored.
Took the engine back to the shop, pulled the pan, looked things over. The rod bearings were coming apart in flakes ?
Like flaking apart in layers ?
Called King, they said there shouldn't be any problems , must have been a bad batch ????
We took everything apart, washed everything up, used Clevite this time this time, did the dyno, and it ran for the 3 years now ?
You guys got any ideas or had any trouble like this ?
( the 2nd engine we just started with the Clevite bearings after the first experience )
