   I don't think the 2nd gen turbo pan is different Jerry.

   --------------------------------------------------------------
   I found some more dwgs.
   This oil pan will fit a Long EZ if you build a MM that looks like this.
   The width is adjusted to clear the pan bolts. Use socket head screws
   and it can be made wider with more capacity. The flange will also
   be stiffer.  Right now it is about 8 quarts which should delay the
   oil heating on takeoff.

   I think Jerry welds them up from .125" thick 6061T6.


   Dave H & John D, This is what I do all day long :)

Paul, et al,

Thanks everybody for your help.

The engine is a 1987 13B,  It is a turbo block, _but wil be NA._  I
don't know if that will change the MM design or not.

Jerry, I did receive an oil pan and gasket from Hayes.  But I can't say that
it is a turbo oil pan per se.  I will be happy to send the oil pan to you.
