Cam Cap Oil Flow
I have a pro-shop rebuilt head in a '77 Spider. Upon assembly and running the car there is a significant amount of what I would call 'squeeking' coming, I believe, from the cam cap area, in spite of being lubed up nicely preassembly. I have removed one of the cam caps to repair a stripped thread that holds the cam cover stud and in the process was introduced to the geometry of the system, with the cam caps being held in place by two undersized studs with short tubes running up the interface between the head and the cam cap to hold the caps in place. I am supposing the undersized studs allow oil to flow up the holes in the head to the top of the cam cap bolt, but where to from there?
My question is... how are the cam caps oiled in this arrangement? My short tubes were quite firmly in place in the head, is this OK? Is there a modification one can make to the cap to improve the oilflow? (drill tiny holes from the inside of the cap to the stud holes?) I want to stop the squeeking!!!
PS - I think the shop did a reasonable job, and in the process of dissassembling and re-assembling the head stamped the cam caps with numbers to identify them, so I presume they are all in the correct location.
I appologize if this is covered in a previous post, but I can't find it if it is.
