Okay. I have an engine I got for cheap, It was dissasembled. I have sorted most of the stuff out and In one of the bins the dude I bought it from gave me was this crazy little piece. Its like a little metal tube with a very small seal on one end. Almost like its made to restrict oil to raise oil pressure to the head or something. However I can not for the life of me figure out where this part goes. I have been to mazda and they didnt know. so if anyone out there remembers what this thing is and where it goes please help me out on this. I've attached some pictures so you can see what I'm talking about.
