    debris when changing engine oil?

    Have a stock 98 TA ls1 w/ 75k miles
    Pulled drain plug and found some needle bearings on the magnet.
    9 were stuck to the magnet, not sure if more drained out.
    Bearing dimensions 6.2 mm (0.254") long 1.65mm (0.65") diameter/very small
    No unusual engine noise before oil drain.
    Drive car very easy.
    Any help w/ this?

    Thanks in advance

    Question is what uses needle bearings. I wouldnt drive it till I found out and replaced it. Epic Failure could happen.

    rocker arms are covered by oiland by well the valve cover...the same place where you poor your oil in..plus with the small size of it..it will very easily circulate around the system..once it gets back into the oil pan...the magnet picks it up...dont worry about it..valvetrain is a mystery to many..me included..but now you know...you can take your valve covers off and see the rockers right there.

    98s are known for this..also the 07 or the 05 i cant remember..ls7 is known to do that...i would suggest getting the harland rockers to replace the rockers when you get a chance..but over all people have been driving with probs like that for relatively long time

    well i just figured that the tolerance would be so tight that it wouldn't be able to move around

    nope. oil windows and just tolerances all over the engine would allow for the needles to work their way down.

    If it were me I'd just replace whats broke and not fix what ain't broke.

    Plus he is going to have to relash the whole valve train vice one cylinder, hardly a time saver.

    If anything Id put in some 1.85 rockers.

    I wouldnt go with an accelerated rocker. You will see a gain yes, but not much. If you ever plan on going with a different cam, you will be limited without changing back.

    All Opinion of course.
