I changed the
oil in my car last weekend before putting it away for the winter (sigh...) But when I inspected the drain plug, there was a shard of metal attached to it.
It is .035" thick and about 3/8" long. I put it against our gauges here at work and it would appear to have an inside radius of about 5/16". It will stick to a magnet (I have a magnetic drain plug).
I've been concerned recently after reading some of the forums regarding
oil temp... I installed a
oil radiator a couple years ago and have never seen the oil get above 130 degrees. So I'm really concerned about sludge, (I will disconnect the radiator over the winter).
I have a couple images in my gallery and will try to get them into my post.

Should I be tearing down the motor??? Help!!!
Thanks,
Dan
