• Adjusting Valves? New Valves...New Head by chrisrandle1 on 20 Aug, 2008 03:33
• Hello;
  
  I am installing new valves into a new head and was wondering how you adjust the valves.  I thought I remembered reading somewhere that you grind the top of the valves.  If so what is the installed height?  Step by step would be nice, but any information that would help me finish this part of the project would be greatly appreciated.
  
  Thanks
  -Chris

• Shims in the lifter buckets.  I am not quite there yet, so i dont know the specs.

• The shims are only for Mechanical heads? That eco is hydro isnt it?
  
  I though the hydraulic heads didnt have an adjustment. I dont own one and have never worked on one so I dont know.

• See page 28 of the Bentley manual
     In the ENGINE Section.
  
     The installeded height of the valve stem
     is calculated relative to the gasket
     surface (valve cover) of the cylinder
     head and the valve seats.  
  
     Maximum: 1.5mm
     Minimum:  0.5mm
  
     At least, I think I've got that right.
     I hope that's what you're looking for.
  
     If it's a "new" cylinder head and "new"
     valves the valve stem height should
     likely be within those specs.
