Re: Oil Pan problem

From at least the late 30s on (and maybe even earlier) there were wooden strips in a trapezoidal shape inserted in channels on either side of the rear main cap. They were driven in for a tight wedge between the cap and block on most if not all of the engines. In the early 50s they went to a cork like composition strip which may have had issues because later on wood was available again. As far as I know the cork discs that were mounted in the depressions on the engine in question were only on the earlier engines and not sure of the function.

Many of the engines used a cork strip that was placed in a channel on the lower bellhousing cover as an additional seal. The cover is a separate piece from the block or oil pan and the strip is positioned after the pan.
