TM 10-3930-671-24 INSTALLING OIL PAN Before  assembling  the  oil  pan,  make  sure  the  contact surfaces are flat and clean of any gasket material or oil. A  form-in-place  gasket  material  is  used  for  sealing  the engine   oil   pan   to   the   crankcase.      The   form-in-place gasket  should  be  applied  to  the  oil  pan  and  filler  blocks as shown here. Tighten  the  screws  in  accordance  with  limits  prescribed in the torque char to avoid looseness or overstressing. NOTE 1.   Parts must be assembled within 20 minutes after applying gasket material. 2.   Caution  must  be  used  In  handling the gasket materials.  Read labels. When  engine  is  completely   assembled   and   filled   with proper oil (see Lubrication section), set tappets according to the following chart.
