The Ford Barn

Several months ago I posted all the drama trying to fix a rear main oil leak on my 33 model B sedan. Problem still not resolved, now on m 4th attempt to fix it.

This post is to ask for information on clearances. I understand a very narrow clearance is required between the crankshaft and the bearing. Can somebody provide the following information for the model B engine:

1) Clearance between crankshaft and bearing
2) Front-end crankshaft clearance
3) Is there any other clearance measurement I need to asses?
4) A simple procedure to measure the clearances (I only have regular hand tools)

Thanks barners. There is a day when my engine will work! Got to keep an optimistic attitude

Doc,

There are many youtube videos on using 'Plastigage' to check the bearing clearances.

Thanks petehoovie. I watched them and I think can do it. Do you know the toque specifications for the caps?
