Well the past two oil changes have netted four camshaft drive sprocket teeth. I have pulled the cover both times and all of the teeth on my cams are present and accounted for. PO had cam chain tensioner failure so these teeth have been rattling around in my engine for at least 17k miles! When I had my timing belt failure the shop removed the pan and replaced the rod bearings. They said they removed several teeth at that time as well. Please Dr Porsche let this be the last of them.




Those babys could do serious trouble in the wrong place.

Are you saying that the camshaft sproket teeth went inside your oil system and collected in the oil pan???

jonnybgood

There are large unpressurized gravity return passages for oil to return to the pan after lubricating the camshafts and lifters. No, that is exactly what I do not want to happen!

edit:My car is the double overhead camshaft engine with a cam chain to drive the intake camshaft.

If I didnt know that there had been a past failure like that....

Well id prolly start sobbing like a little girl

Yeah that can never be a good thing...better to find it stuck to the magnet than have it show itself in other places where you don't want it though.

oh man, that doesn't look good. i've got my engine torn down now, and you would be amazed at the places those little tiny metal bits can collect. i've thoroughly washed everything and still i find little tiny metallic flakes.

good thing is....yours are big enough that once they fall into the pan, they probably won't be picked up through the oil pickup tube

Not a worry. There is a nice metal screen on the oil pickup to prevent stuff like that from getting into the oiling system. They'll just slosh around in the oil until the magnet on the oil plug catches them.

Don't worry about it.

Thanks Dal and Jo.

That was what I was worried about is the oil pick up sucking them up into the pump. I haven't seen one of these blocks up close except in pictures so I don't know the system.

Still hope that magnet gets them all at some point. I suppose the more vigorously I drive the more likely I will pick them all up!
