Sorry for the long story...
Couple of weeks ago, I was driving on the highway, when the engine suddenly started making a real ugly metallic knock. Stopped, listened and decided it came from the passenger's side head. It knocked very loud, but not constantly, and it ran very rough, without smoke though. It sounded like a miss. It was so ugly, I towed it home.
I first checked the valvetrain; took off the valve covers and turned the engine over a couple of times by starter. Everything seemed fine.
Injectors checked with a pop tester, they all did their thing, wich can be expected from rebuild injectors with only a couple of hundred miles on them.
So I decided to fire it up. Started instantly, but ran quite rough and now made a new sound at idle: The squeeking sound you get when you're machining steel without enough lubrication. :eek:
When I took out the dipstick there where metal chips at the end of it.... :mad:
So I drained the pan and took these out with the help of a magnetic pen:

Looks familiar to anyone??
Any ideas about the origin of the chips?
Dropping the oilpan will probalby give me more bad news. Or shouldn't I bother, and just take out the entire engine?
Thanks for your thoughts!
