Can anyone tell me what this dowel is for? I thought it was for the plenum but nope.... bit worried because I found it laying on the top of my engine by the lifters, only one.. and there are none in my VR head gasket set. Thanks

 

Looks like valve cover gasket or one of the 2 intake plenum dowels

 

2x on the valve cover gasket dowel

 

that's it, thanks. None went down into the motor thank G
