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.
