[DeTomaso] oil-burning question - rope trick

[SOBill at aol.com]

The valve springs can be removed and the oil seals can be installed  with the 
heads on the car.
 
 
The type of valve spring compressor used to do this 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.
 
Articles covering this procedure always show 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 simplify the 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 or 
seals. After the springs or seals  have been changed, move the piston back down a 
little and pull the nylon cord  out. 
 
Have fun,
