I had a valve job performed on my 1999 Eclipse Spyder 2.4L. After installing the head I noticed the camshaft positon sensor housing is missing. I called the machine shop and of course they can't find it and won't own up to losing it. Does anyone have a parts break down so i can see what the part looks like and what its called so I can order a new one? Is there a good source for ordering a part like this? Thanks for any help.
