I have about 25 hours of use on my Ford 3000 since I purchased it. I am noticing after working her hard I get some oil seeping out on the left side in between the head and the block. My question is how difficult of a project will this be? I have done plenty of external repairs, but no internal repairs. Looking thru my shop manual it looks like it will involve; removing the rocker arm cover, rocker arm assembly (3-4 bolts and the assembly will lift out whole?), unbolt the head and remove? What about pistons and such? Drop the oil pan and unbolt them from below?
