I just completed installing the oil pan on my 235 with the engine in the truck. The neighbor kids within a three block radius are now fluent in all cuss words, and all of the combinations of said cuss words, and how they are to be arranged in order to create grammatically correct sentences. I believe that I let the adhesive "skin up" too long and had difficulties keeping the end seals from peeling off at the ends. The pan does not have much wiggle room front to back due to the front motor mount , adding to all of the fun.
HRL is exactly correct about the arrangement of the gaskets and in what order they need to be installed, whether on a stand or on your back under the truck.
