Well just got done with and engine build and went to go prime the pump. I have the dizzy just placed in the hole to cover it and when I went to remove it it pulled the pump drive up with it and then I heard the dang clip falling somewhere into the darkness of the engine. I removed the timing cover thinking I could maybe get lucky and find it just sitting there, but no luck so far. I shoved a magnet all around in there but still no luck. Is that clip steel or a aluminum? I know its not plastic, since I installed it. I am about to remove the pan to find the dang thing. Anyone else have this problem before? Are the chances pretty good that the clip is just sitting at the bottom, and will never cause a problem? With a new eng build I am kind a leary about leaving it in there, but then again not to wild about taking it apart again. Any help would be appreciated.
