okay boy's I'm putting no 2 motor in my explorer, when I pulled the motor I saw the intake gasket has been leaking antifreze, well by learning the hard way I know I need to replace the head gaskets also,(when we replaced the intake gasket on motor no 1 the heads gasket started to leak on cyc. no 4)so I will have the whole top of the motor off.

so is there any GOODIES I should put in this motor at this point?
it has only 108000 miles on it the first motor made it to 238000 and still runs just weak.

 

if this is the OHV you can get rid of the spring between the rockers and replace it with a alunium tube to keep them in place

open up the port on the exhaust side
