A buddy of mine performed a routine oil change on his 98 k1500 5.7 w/117k miles. He reports metal on the magnet for the first time. Tiny pieces of iron all standing at attention. The oil went into a closed tub uninspected.
No other symptoms..knocking etc. Oil pressure at startup about 40....lowers to 25 at hot idle.
Based on the your experience, any thoughts on the source? no wise ass remarks like, from the engine etc.
Thanks.
