Woodruff key disappeared into the abyss

[Awk34]

While pressing on a new crank damper, I heard a 'ping' and new it was that damn woodruff key. I pulled the damper back off and sure enough it was gone. I've searched all through there, pulled the seal off, tried digging around with picks and a magnet (although a large magnet on a straight stick, not the best tool for that) to no avail. I'm dreading the thought of having to disassembly the engine again just to get that damn key back. Do you guys know of another way? If it fell into the oil pan, should I just leave it there? Is it possible it fell into one of the oil pump holes? Please Help!

It's not going anywhere.  Leave it for the next guy.  It might end up on your drain plug magnet.

It's a relief to hear you say that. Do you have any tips on making sure the next one doesn't fall out when installing the damper? Is it a bad idea to glue it in place?

A dab of wheel bearing grease should keep it in place until you slide the damper on.

Is your oil slinger intact? If you pushed the woodruff key thru into the pan, it would probably destroy the circular metal oil slinger unless you were very lucky and the notch on the oil slinger was perfectly aligned to the key.

Make sure there are no burrs on the damper that might be grabbing the woodruff key as it slides on, lightly go over the edges with a fine file.

I wonder if the oil slinger is the "metal plate" that somebody was seeing in a recent thread about the woodruff key.  He was just trying to replace the seal and ended up with quite a mess.  His key was jammed in the keyway at an angle.

I've read that some engines didn't come with the slinger and many people just leave it out after working on the engine.

Here's the thread -

The Honsowetz modify book suggest leaving it out? Don't understand that but did it anyway on my 280. The 240 has one for sure after I researched a liitle better.

Interesting....I figured if the factory installed it, so would I. All of the engines I’ve taken apart have had them. Wonder why it’s called an oil slinger?  
 

Here’s one those little suckers! Probably keeps oil off the seal would be my guess.

I read it slings oil back onto the lower timing chain sprocket, if I remember right.

Lots of reasons or guesses here.

It's called an "oil thrower".
