[DeTomaso] Best valve spring compressor and keep the valves in place

[SOBill at aol.com]

Doug,
 
The valve spring compressor is Moroso # 62370 and is sold by Jegs  as # 
710-62370 for ~$82.
 
A similar compressor is sold by Summit as #SUM-906784 for  ~$42.
 
Google Moroso 62370 and you will find many sellers ...... maybe a  bargain 
can be found.
 
The articles always shown the valves being held closed by  compressed air 
with the piston at TDC. This isn't that simple, if the piston is  not at exact 
TDC, 100psi of air will likely make the crank rotate forward or  backward. This 
means you need to put the car in gear and use the e-brake to hold  the engine.
 
A way to eliminate this problem and also eliminate the  need for compressed 
air is to move the piston down a fair  ways before TDC and feed as much medium 
size nylon cord thru the spark  plug hole as you can get. Move the piston 
toward TDC. The nylon cord will  conform to the combustion chamber shape and hold 
the valves closed. You can now  use the spring tool to change the springs. 
After the springs have been changed,  move the piston back down a little and pull 
the nylon cord out. 
 
Have fun,
