Most likely spots are: oil cooler seals, flywheel seal, pushrod seals. None of 
these are easy to get to. You have to pull the engine to replace the flywheel 
seal and then pull the heads to replace the pushrod tubes and seals. The oil 
cooler seals can be replaced in the car, but it is quite a job to get in there.

I'm amazed that you've seen this picture. I think that only one of my books 
shows it and I don't know a tool # for it. Most people just bolt these on and 
adjust them so they point nicely to the filler neck on the body. I made the 
gauge, but I'm not convinced that it is important. Russ, what do you think?

I often find that the flange on the bottom of that tube is bent such that it can't 
seal well. Fortunately, if you have a good vice it is rather easy to straighten 
out flat again. You have to take it out to do this however. Be careful of the 
gasket, it may be hard/impossible to find a replacement.
